From 56bbd19ff4efe2b1a05a10ecaa0f27ff39616e29 Mon Sep 17 00:00:00 2001 From: Jack Ye Date: Tue, 15 Sep 2026 02:10:49 -0700 Subject: [PATCH 01/74] test(python): cover namespace operations without pylance (#4174) The "Test without pylance or pandas" CI job only ran `test_table.py`, so the regression fixed in #3606 had no guard: sync namespace operations used to route through the Python `lance_namespace` client, whose `dir` implementation ships in the optional `pylance` extra, so `lancedb.connect(path).list_namespaces()` failed with `No module named 'lance'` while the async API worked. Adds `python/python/tests/test_namespace_no_pylance.py` and runs it in that job. Its `without_pylance` fixture blocks `lance` imports, so the guard also fires in environments that do have `pylance` installed. Coverage: the original reproducer, nested namespace lifecycle, namespaced and root table lifecycle, the async path, and the one API that legitimately still needs `pylance` (`namespace_client()`). Verified the guard actually catches the regression: against `lancedb==0.33.0`, three of these tests fail with the original error; against a fixed build all pass.

charset=UTF-8 Content-Transfer-Encoding: 8bit Update the Rust workspace Lance dependencies and Java lance-core from v12.0.0-beta.18 to [v13.0.0-beta.1](https://github.com/lance-format/lance/releases/tag/v13.0.0-beta.1), and refresh Cargo.lock; no compatibility fixes were required. Validation passed: `cargo clippy --quiet --workspace --tests --all-features -- -D warnings`, `cargo fmt --all --quiet`, and `git diff --check`. Also fixes the flaky Node test `when optimizing a dataset › cleanups old versions` that failed the NPM Publish Linux test jobs on this PR. The test captured `new Date()` (millisecond precision) in the same millisecond as the last commit, while Lance compares version timestamps at nanosecond precision, so that version was not pruned. The test now waits for the clock to tick to the next millisecond before taking the cutoff. This is a pre-existing flake on `main` since #4160, unrelated to the Lance upgrade. --------- Co-authored-by: Yang Cen Co-authored-by: Claude Fable 5.1 --- Cargo.lock | 85

serde_with v3.23.0

Changed

  • Update syn and darling dependencies to use syn v3 (#992)
  • Update dev-dependencies to newer versions (#993)
  • Update base64 to a newer version. This should not have any API change, but some error messages might change. (#993)
  • serde_as can now parse cfg_attr(true, ...) and cfg_attr(false, ...) (#995) true/false are new literals as of Rust 1.88 but need to be parsed explicitly with the syn types. This is used when emitting schemars annotations.

The utility is applied after default/configured header construction and dynamic header merging, so it also covers retry requests. Invalid dynamic-header values are no longer echoed, and regression coverage verifies that credentials are redacted while ordinary diagnostic headers remain visible.

Addresses the token-cache part of [Colin's review](https://github.com/lancedb/lancedb/pull/4173#issuecomment-5674048100). Adds an explicit, opt-in persistent OAuth token cache shared by Rust, Python, and Node clients, plus `login` / `status` / `logout` session APIs, so short-lived processes (CLIs, scripts, notebooks) reuse one session instead of restarting a browser or device flow on every start. - **Opt-in and minimal**: existing callers stay memory-only and lazy. Only refresh tokens are persisted (never access tokens, never client secrets), so there are no local token-expiry decisions to get wrong when clocks move. Each process start performs one silent refresh grant. - **Hardened file backend**: private directory (`0700`), per-record files (`0600`), owner validation, symlink rejection, and atomic `rename` replacement. Corrupt, truncated, unknown-version, or permission-invalid records fail with actionable errors naming the file. Native keyring backends were evaluated (keyring crate routes Linux through D-Bus/zbus: heavy deps, headless/CI flakiness) and are deferred; the file store is the explicit opt-in, not a downgrade from a keyring. - **Cache key**: SHA-256 of the canonical identity (issuer, client ID, sorted/de-duplicated scopes, flow, public/confidential), so no secret appears in a filename and distinct identities never collide. Versioned record schema (`version: 1`). One record per identity: last login wins, documented. - **Cross-process rotation locking**: per-key `fs4` file lock (`flock` / `LockFileEx`) around the refresh critical section — acquire, reread the durable record, refresh exactly once, atomically store the rotated refresh token, release. The OS releases locks on process death, so crashes cannot strand stale locks. Only confirmed `invalid_grant`/`invalid_token` deletes a record and reauthenticates; transport, 5xx, 429, and parse failures retain it. - **Session APIs**: `OAuthSession::login/status/logout` in Rust, `lancedb.remote.OAuthSession` (async) in Python, `OAuthSession` class in Node. `status` returns non-secret metadata only. `logout` removes only the local credential — provider revocation (RFC 7009) is a deliberate follow-up, and local logout never terminates browser SSO. Azure managed identity is rejected for persistence (machine identity stays in memory); client credentials have nothing refreshable to persist and stay memory-only. - No CLI binary exists in this repo, so this ships library APIs plus doc examples in all three languages. Tests: Rust unit + mock-IdP integration (cache-key canonicalization/separation, record versioning/corruption/truncation/symlink/owner/perms, lock serialization + release, two concurrent providers proving no `invalid_grant` and correct rotation, transient-failure retention, `invalid_grant` delete + reauthenticate, login/status/logout lifecycle, client-credentials no-op, IMDS rejection, secret redaction); Python lifecycle + a true two-subprocess cross-process reuse test (second process refreshes once, never hits the device endpoint); Node lifecycle + device-flow login test. Local builds were skipped in development; CI validates all bindings. --------- Co-authored-by: Xuanwo --- Cargo.lock | 84 + docs/src/js/classes/OAuthSession.md | 105 +

Persistent OAuth token cache and session lifecycle APIs. +//! +//! By default, OAuth sessions are kept in process memory only (see +//! [`OAuthHeaderProvider`](crate::remote::OAuthHeaderProvider)). Short-lived +//! processes such as CLI tools, notebooks, or scripts would otherwise have to +//! run a full interactive browser or device flow on every start. Configuring +//! [`TokenCacheOptions`] on an [`OAuthConfig`](crate::remote::OAuthConfig) opts +//! in to an explicit, hardened, on-disk cache that stores only the refresh +//! token plus non-secret metadata, so a second process can silently refresh +//! instead of re-prompting. +//! +//! Security properties: +//! +//! - Opt-in only; callers that do not configure a cache stay memory-only. +//! - Only refresh tokens are persisted. Access tokens never touch disk, so +//! there are no local expiry decisions to get wrong when clocks move. +//! - No client secret is ever stored. +//! - The cache directory is private (`0700`) and each record is `0600`, +//! owner-checked, and symlink-rejected on Unix; records are replaced +//! atomically via `rename` so a crash can never leave a torn file. +//! - Cache filenames are SHA-256 hashes of the canonical issuer, client, +//! scope, flow, and client-auth identity. No secret appears in a filename. +//! - Refresh-token rotation is serialized across processes with a per-key +//! advisory file lock (`flock` on Unix, `LockFileEx` on Windows). The +//! operating system releases these locks when a process dies, so a crash +//! cannot leave a stale lock behind. +//! +//!

A file is now identified by where its store resolves it, so the source's own root and a clone's registered reference to that root sign the same while different bases stay distinct; compaction products are matched the same way. Sidecars live in one `_computed/` at the table root shared by main and its branches; a shallow clone reads through the base it was cloned from and keeps a copy. Pruning collects references across every branch, and the staleness walk treats the versions a branch does not hold as unknown. Stamps written before this change no longer match, so the first refresh after upgrading recomputes once; a deep clone, which copies no sidecar, still starts over. --- rust/lancedb/src/table/freshness.rs | 414 +++++++++++++++++++++++----- rust/lancedb/src/table/refresh.rs | 71 ++++- 2 files changed, 413 insertions(+), 72 deletions(-) diff --git a/rust/lancedb/src/table/freshness.rs b/rust/lancedb/src/table/freshness.rs index e7a1841e6..b2c933cd8 100644 --- a/rust/lancedb/src/table/freshness.rs +++ b/rust/lancedb/src/table/freshness.rs @@ -17,16 +17,17 @@ //! only the reference.

From f12996557f866e0ec8e4fc887e2f3298f3a169a7 Mon Sep 17 00:00:00 2001 From: Jack Ye Date: Tue, 15 Sep 2026 12:13:39 -0700 Subject: [PATCH 07/74] feat(remote): support materialized view APIs (#4180) ## Summary Align the experimental materialized-view HTTP transport with the equivalent Table API shape and add remote materialized-view support across Rust, Python, and TypeScript. This is an intentional breaking change to the experimental materialized-view surface. Materialized-view creation performs an initial refresh by default. The create endpoint returns `202 Accepted` with `{ "job_id": "..." }`; blocking SDK creation waits for that job before returning a populated view. `with_no_data` / `withNoData` explicitly creates only the definition and empty backing table. ## Route comparison | Operation | Materialized-view API | Equivalent Table API | | --- | --- | --- | | Create | `POST /v1/materialized_view/{id}/create` | `POST /v1/table/{id}/create` | | Describe/open | `POST /v1/materialized_view/{id}/describe` | `POST /v1/table/{id}/describe` | | List | `GET /v1/namespace/{id}/materialized_view/list` | `GET /v1/namespace/{id}/table/list` | | Refresh | `POST /v1/materialized_view/{id}/refresh` | asynchronous Table mutation pattern | | Drop | `POST /v1/materialized_view/{id}/drop` | `POST /v1/table/{id}/drop` | Create, describe, refresh, and drop identify the target in the singular item path instead of duplicating it in the request body. Create and drop require `202 Accepted` with a valid job ID. List is a namespace-scoped GET with opaque pagination tokens. The Rust list API now returns view names, matching Table listing and the existing Python and TypeScript APIs. ## Python API changes | Operation | Synchronous API | Asynchronous API | Table/job pattern | | --- | --- | --- | --- | | Create and wait | `DBConnection.create_materialized_view(...)` | `await AsyncConnection.create_materialized_view(...)` | Returns a materialized-view handle after its initial-population job finishes | | Submit create | `DBConnection.create_materialized_view_async(...) -> Job[None]` | `await AsyncConnection.create_materialized_view_async(...) -> AsyncJob[None]` | Matches job-returning Table mutations such as `create_index_async` | | Open | `DBConnection.open_materialized_view(...)` | `await AsyncConnection.open_materialized_view(...)` | Opens the backing Table plus its definition | | List | `DBConnection.list_materialized_views()` | `await AsyncConnection.list_materialized_views()` | Returns names like Table listing | | Refresh and wait | `MaterializedView.refresh(...)` | `await AsyncMaterializedView.refresh(...)` | Returns the typed refresh result after the job finishes | | Submit refresh | `MaterializedView.refresh_async(...) -> Job[RefreshMaterializedViewResult]` | `await AsyncMaterializedView.refresh_async(...) -> AsyncJob[RefreshMaterializedViewResult]` | Matches `Table.refresh_column_async`; remote job handles expose the server job ID | | Drop | `DBConnection.drop_materialized_view(...)` | `await AsyncConnection.drop_materialized_view(...)` | Matches blocking `drop_table` | | Submit drop | `DBConnection.drop_materialized_view_async(...) -> Job[None]` | `await AsyncConnection.drop_materialized_view_async(...) -> AsyncJob[None]` | Matches `drop_table_async`; remote handles expose the server cleanup job ID | The materialized-view handle exposes its backing Table through `.table`, so normal Table query, search, and index APIs apply. Definition lookup and refresh are backend-aware rather than depending on local schema metadata. TypeScript exposes the equivalent blocking/job drop pair as `dropMaterializedView` and `dropMaterializedViewAsync`. --- docs/src/js/classes/Connection.md | 60 ++- docs/src/js/classes/MaterializedView.md | 2 +- nodejs/__test__/materialized_view.test.ts | 26 +- nodejs/__test__/remote.test.ts | 18 +- nodejs/lancedb/connection.ts | 53 ++- nodejs/lancedb/materialized_view.ts | 22 +- nodejs/lancedb/table.ts | 9 +- nodejs/src/connection.rs | 34 +- nodejs/src/table.rs | 13 + python/python/lancedb/_lancedb.pyi | 22 + python/python/lancedb/db.py | 176 ++++++- python/python/lancedb/materialized_view.py | 56 ++- python/python/lancedb/namespace.py | 101 +++- python/python/lancedb/remote/db.py | 72 ++- .../python/tests/test_materialized_views.py | 264 +++++++++- python/src/connection.rs | 70 ++- python/src/error.rs | 1 + python/src/table.rs | 45 ++ rust/lancedb/src/database.rs | 71 ++- rust/lancedb/src/materialized_view.rs | 449 +++++++++++++----- rust/lancedb/src/materialized_view/refresh.rs | 20 + rust/lancedb/src/remote/db.rs | 221 +++++++++ rust/lancedb/src/remote/table.rs | 224 ++++++++- rust/lancedb/src/table.rs | 23 + 24 files changed, 1820 insertions(+), 232 deletions(-) diff --git a/docs/src/js/classes/Connection.md b/docs/src/js/classes/Connection.md index 18c1deb3b..d46d414d3 100644 --- a/docs/src/js/classes/Connection.md +++ b/docs/src/js/classes/Connection.md @@ -180,13 +180,13 @@ abstract createMaterializedView( Define a materialized view named `name` over the table `source`. -The view is created empty, with the query recorded in its schema -metadata; `view.refresh()` computes the rows.

The cause is the shared Tokio runtime backing every async call: it's never told to shut down at normal process exit, only reset (and deliberately leaked) on `fork()`. Its worker threads keep running, uncoordinated with the interpreter, until the process actually ends, and if one is mid-task exactly as `Py_Finalize` starts tearing down interpreter state, it can panic on state that's already gone. That panic happens on a background thread with no PyO3-wrapped call frame to catch it, so Rust aborts the whole process instead of just failing that one call. This PR gives the runtime a coordinated, bounded shutdown by registering a Python `atexit` callback that runs while the interpreter is still fully valid. Getting the exit lifecycle right took a few rounds of review. Earlier versions freed the runtime as soon as `Arc::strong_count` looked low, but that's the wrong signal — it reflects who currently holds a reference, not who's logically still in flight. That mistake showed up three ways: a caller could dereference memory already freed out from under it; an install already in progress could finish invisibly after `shutdown()` had already decided there was nothing to do; and a spawned task could end up as the final owner of the `Runtime`, so completing it dropped the runtime from inside one of its own worker threads, which Tokio itself forbids and panics on (this reproduced unprompted in this branch's own test suite). Fixing all three meant replacing reference-count-based tracking with an explicit counter of in-flight top-level calls that `shutdown()` waits on directly. This was accomplished with the following changes: - The runtime lives in an `ArcSwapOption`, where `Tagged` pairs the `Runtime` with the fork generation it was built in. - An `OUTSTANDING` counter, incremented before a top-level `spawn`/`spawn_blocking`/`block_on` call does anything else and decremented only once it has truly finished (via an `OutstandingGuard` token that carries no reference to the runtime), is what `shutdown()` waits on — not `Arc::strong_count` or whether the slot looks empty. This closes the install-race and makes it impossible for a task's own completion to be the runtime's final drop. - Once `shutdown()`'s bound elapses, it stops waiting and attempts retirement anyway, rather than returning with the runtime and its workers left fully alive. - `spawn`/`spawn_blocking` use `Handle::try_current()` to pin any nested spawn (`future_into_py` spawns a task that itself spawns a second one for the real work) to whichever runtime is already executing it, so a reclaim landing between the two calls can't split one logical operation across two different runtime instances. - The fork-child handler now only bumps a bare `GENERATION` counter — no `ArcSwapOption` call of any kind from that context, since `swap`/`compare_and_swap` do real reader-reconciliation work (thread-local state, potentially an allocation) that isn't safe in a forked child. `get_runtime()` compares its installed runtime's generation against the live counter from ordinary context and rebuilds on a mismatch. - Registered `shutdown_runtime` as a Python `atexit` callback in the `_lancedb` module init, running with the GIL released (`Python::detach`) since the bounded wait could otherwise deadlock against any in-flight task that itself needs the GIL. ### Testing - Unit tests in `runtime.rs` cover: shutdown with no runtime created, shutdown after use and lazy rebuild afterward, calling shutdown twice in a row, a concurrent stress test racing many threads against shutdown, a nested-spawn test reproducing `future_into_py`'s own spawn-within-a-spawn shape under concurrent shutdown, a test confirming a top-level task in flight survives a concurrent shutdown reclaim, and a test forcing the install-vs-shutdown race directly. - Built the wheel and ran a concurrent reproducer (many threads hammering the client while `atexit` fires) over 100 times with no hangs or crashes, plus a 30-second-join variant and repeated runs of a short-lived process confirming clean exits with no added latency. --------- Co-authored-by: Claude Sonnet 5 --- Cargo.lock | 1 + python/Cargo.toml | 1 + python/src/lib.rs | 26 ++- python/src/runtime.rs | 490 +++++++++++++++++++++++++++++++++++++++--- 4 files changed, 485 insertions(+), 33 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index 090e2c654..0f30926f5 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -5597,6 +5597,7 @@ dependencies = [ name = "lancedb-python" version = "0.39.0-beta.8" dependencies = [ + "arc-swap", "arrow", "async-trait", "bytes", diff --git a/python/Cargo.toml b/python/Cargo.toml index d7ec8cd61..314664e14 100644 --- a/python/Cargo.toml +++ b/python/Cargo.toml @@ -15,6 +15,7 @@ name = "_lancedb" crate-type = ["cdylib"] [dependencies] +arc-swap = "1.9" arrow = { workspace = true, features = ["pyarrow"] } async-trait.workspace = true bytes.workspace = true diff --git a/python/src/lib.rs b/python/src/lib.rs index f83776e7b..0bd7d5d6d 100644 --- a/python/src/lib.rs +++ b/python/src/lib.rs @@ -8,8 +8,8 @@ use expr::{PyExpr, expr_col, expr_func, expr_lit}; use index::IndexConfig; use permutation::{PyAsyncPermutationBuilder, PyPermutationReader}; use pyo3::{ - Bound, PyResult, Python, pymodule, - types::{PyModule, PyModuleMethods}, + Bound, PyResult, Python, pyfunction, pymodule, + types::{PyAnyMethods, PyModule, PyModuleMethods}, wrap_pyfunction, }; use query::{FTSQuery, HybridQuery, Query, VectorQuery}; @@ -38,8 +38,24 @@ pub mod sql; pub mod table; pub mod util; +/// Shut down the shared Tokio runtime (see `runtime::shutdown`). +/// +/// Registered below as a Python `atexit` callback rather than called +/// directly: `atexit` runs while the interpreter is still fully valid, +/// which is the coordinated, bounded exit the runtime otherwise never gets. +/// +/// Runs the actual wait with the GIL released (`Python::detach`): shutdown +/// blocks the calling thread waiting on the runtime's own worker threads, +/// and if any in-flight task needs the GIL to finish (e.g. one that calls +/// back into Python), holding it here while waiting on that same task would +/// deadlock rather than time out. +#[pyfunction] +fn shutdown_runtime(py: Python<'_>) { + py.detach(|| runtime::shutdown(std::time::Duration::from_secs(5))); +} + #[pymodule] -pub fn _lancedb(_py: Python, m: &Bound<'_, PyModule>) -> PyResult<()> { +pub fn _lancedb(py: Python, m: &Bound<'_, PyModule>) -> PyResult<()> { let env = Env::new() .filter_or("LANCEDB_LOG", "warn") .write_style("LANCEDB_LOG_STYLE"); @@ -98,5 +114,9 @@ pub fn _lancedb(_py: Python, m: &Bound<'_, PyModule>) -> PyResult<()> { m.add_function(wrap_pyfunction!(expr_lit, m)?)?; m.add_function(wrap_pyfunction!(expr_func, m)?)?; m.add("__version__", env!("CARGO_PKG_VERSION"))?; + // Give the shared runtime a coordinated, bounded shutdown at normal + // process exit -- see `shutdown_runtime` and `runtime::shutdown` for why. + py.import("atexit")?

This bites row-at-a-time inserts hardest: a one-row batch with no value for an optional column is trivially all-null, so most such writes failed. pyarrow infers `null` as the column's type, and the write path had no handling for it — casting to the table's type dropped the field metadata that identifies the column as `lance.json`, so lance rejected the batch (`` `val` should have type json but type was large_binary ``). A null-typed input column now becomes typed nulls matching the table's field exactly, metadata included. **Unlabelled JSON text was stored raw.** JSON supplied as plain strings (what pyarrow infers for a column of `str`) was cast to the column's `LargeBinary` storage type and relabelled `lance.json`, putting unparsed text where JSONB was expected. Reads returned the text unnormalized and `json_extract` failed with `InvalidJsonb`. Lance-core does the JSONB encoding, but only for input labelled `arrow.json`, so string input is now labelled rather than cast — at the top level and inside structs. Both fixes are in the shared Rust write path, so they apply to any binding, including hand-built Arrow tables that never pass through Python's list-of-dicts type inference. `_align_field` gets the same JSON-string fix for the legacy Python `_sanitize_data` path, which `on_bad_vectors` and embedding functions still route through. The blob v2 half of the issue landed separately in #4065, which added a `DataType::Null` arm to blob coercion. This PR keeps that implementation and adds end-to-end add-path coverage for it. The tests from #4066 are included here and pass, so that PR's Python-layer inference changes are no longer needed to close the issue.

charset=UTF-8 Content-Transfer-Encoding: 8bit ## Issue Fixes #4063 ## Background The Node.js SDK currently requires callers to know the Arrow extension metadata needed to represent JSON fields. This makes a common LanceDB schema type unnecessarily verbose and easy to get wrong. ## Changes - Add `makeJsonField(name, nullable = true)` to create a UTF-8 Arrow field with the `arrow.json` extension metadata. - Re-export the helper from the public Node.js entry point. - Add coverage for the default nullable behavior, explicit non-nullable fields, and the extension metadata. - Add the generated TypeDoc function page and public globals entry, including a usage example. ## Implementation The helper uses the existing Apache Arrow `Field` type and sets `ARROW:extension:name` to `arrow.json`, matching the metadata convention already used by LanceDB. ## Compatibility This is an additive Node.js API. Existing schema construction and Arrow behavior are unchanged. ## Verification - `pnpm test -- arrow.test.ts --runInBand` — 236 tests passed. - `pnpm exec biome ci lancedb/arrow.ts lancedb/index.ts __test__/arrow.test.ts` — passed. - `git diff --check` — passed. ## Not run / known limitations - `pnpm build` and `pnpm run docs` were attempted after expanding the checkout. Both are blocked locally by the native binding build/type declarations: Cargo did not complete, and TypeDoc reported the missing generated `nodejs/lancedb/native` module. The docs files were generated from the updated TypeScript comments; full build and docs validation are left to CI. --- docs/src/js/functions/makeJsonField.md | 36 ++++++++++++++++++++++++++ docs/src/js/globals.md | 1 + nodejs/__test__/arrow.test.ts | 16 ++++++++++++ nodejs/lancedb/arrow.ts | 24 +++++++++++++++++ nodejs/lancedb/index.ts | 1 + 5 files changed, 78 insertions(+) create mode 100644 docs/src/js/functions/makeJsonField.md diff --git a/docs/src/js/functions/makeJsonField.md b/docs/src/js/functions/makeJsonField.md new file mode 100644 index 000000000..bfa6fd6d7 --- /dev/null +++ b/docs/src/js/functions/makeJsonField.md @@ -0,0 +1,36 @@ +[**@lancedb/lancedb**](../README.md) • **Docs** + +*** + +[@lancedb/lancedb](../globals.md) / makeJsonField + +# Function: makeJsonField() + +```ts +function makeJsonField(name, nullable): Field +``` + +Create an Arrow field backed by LanceDB's JSON extension type. + +## Parameters + +* **name**: `string` + The field name. + +* **nullable**: `boolean` = `true` + Whether the field accepts null values. + +## Returns + +`Field` + +## Example + +```ts +import { connect, makeJsonField } from "@lancedb/lancedb"; +import { Schema } from "apache-arrow"; + +const schema = new Schema([makeJsonField("metadata")]); +const db = await connect("/path/to/database"); +await db.createTable("items", [{ metadata: '{"source":"api"}' }], { schema }); +``` diff --git a/docs/src/js/globals.md b/docs/src/js/globals.md index 422c6c428..7e8344054 100644 --- a/docs/src/js/globals.md +++ b/docs/src/js/globals.md @@ -170,6 +170,7 @@ -

Rust and Python expose the object ID, location, canonical decimal version, metadata, and availability separately from the OCI image digest.

Normalize FTS columns to the public path after parsing the server response, using the same field-ID-based conversion as native tables. Keep the physical paths on the wire: existing clients need them to resolve the Arrow schema.

As a result, the native login flow launches a real browser; the [failing macOS main job](https://github.com/lancedb/lancedb/actions/runs/35067074667/job/104699667840) ends by terminating an orphaned Safari process. Set the no-op browser helper while loading Jest configuration, before creating sandboxes and workers, so both local and CI tests inherit it. Check the inherited process environment before OAuth login to catch regressions without opening a browser. Windows uses a no-op command fixture. Test deadlines and worker counts are unchanged. A negative control restoring the sandbox-only assignment fails in the new pre-login check. The full macOS test suite passes with the standard test launcher; the Windows helper has not been executed locally. The [first hosted macOS run](https://github.com/lancedb/lancedb/actions/runs/35071525843/job/104713928139) passes all 843 tests (5 skipped), with no Safari process in the job log. Further normal runs are needed to establish sustained stability. --- nodejs/__test__/fixtures/oauth_browser.cmd | 3 +++ nodejs/__test__/oauth.test.ts | 13 ++++++++++--- nodejs/jest.config.js | 9 +++++++++ 3 files changed, 22 insertions(+), 3 deletions(-) create mode 100644 nodejs/__test__/fixtures/oauth_browser.cmd diff --git a/nodejs/__test__/fixtures/oauth_browser.cmd b/nodejs/__test__/fixtures/oauth_browser.cmd new file mode 100644 index 000000000..8e97db307 --- /dev/null +++ b/nodejs/__test__/fixtures/oauth_browser.cmd @@ -0,0 +1,3 @@ +@rem SPDX-License-Identifier: Apache-2.0 +@rem SPDX-FileCopyrightText: Copyright The LanceDB Authors +@exit /b 0 diff --git a/nodejs/__test__/oauth.test.ts b/nodejs/__test__/oauth.test.ts index 0a04bb2aa..627da786f 100644 --- a/nodejs/__test__/oauth.test.ts +++ b/nodejs/__test__/oauth.test.ts @@ -3,6 +3,7 @@ import * as fs from "fs"; import * as http from "http"; +import { execFileSync } from "node:child_process"; import * as os from "os"; import * as path from "path"; import { OAuthConfig, OAuthFlowType, OAuthSession } from "../lancedb/oauth"; @@ -23,9 +24,15 @@ function deviceConfig(issuerUrl: string, cacheDir: string): OAuthConfig { describe("OAuthSession", () => { beforeAll(() => { - // Point the Rust browser helper at a no-op so device-flow logins never - // open a real browser window during tests. - process.env.LANCEDB_OAUTH_BROWSER = "/usr/bin/true"; + // Child processes inherit the real environment, just as Rust reads it. + // Fail before login if the browser override only exists in Jest's sandbox. + const browser = execFileSync( + process.execPath, + ["-p", "process.env.LANCEDB_OAUTH_BROWSER ??

Rebase to `main` once #4173 and #4179 merge. ## What moved to the `oauth2` crate (5.0, no default features) - Authorization URL generation and CSRF state (`authorize_url`, `CsrfToken`) - PKCE S256 challenge/verifier generation and code exchange - Client-credentials, authorization-code, refresh-token, and device-code grant request construction - Device authorization request and the device token polling loop (`authorization_pending`, `slow_down` +5s, expiry deadline, denial, network backoff capped at 10s) - Standard success/error response parsing (`RequestTokenError`) - Token-endpoint client authentication and standards-compliant parameter encoding (RFC 6749 2.3.1 Basic encoding) LanceDB keeps ownership of OIDC discovery (compared `openidconnect`: no measurable win for our 3-field metadata + strict validation, at real dependency cost), HTTPS-or-loopback endpoint enforcement, the loopback callback server, browser/stderr prompts, token caching and refresh orchestration, and the dedicated hardened Azure IMDS source, which is unchanged. ## Client authentication methods New `ClientAuthMethod` enum (`none` | `client_secret_basic` | `client_secret_post`), exposed in Rust, Python, and Node. Unset resolves to `client_secret_basic` when a secret is present (RFC 6749 2.3.1 recommendation and the normal Okta confidential-app default, so a default Okta app works without weakening its configuration) and to `none` for public clients (PKCE/device). Explicit `none` with a secret, or basic/post without one, is rejected. The method applies to client credentials, code exchange, refresh, and device requests. Deliberate behavior change: confidential clients previously always sent the secret in the POST body; they now default to Basic (Keycloak accepts both). No `audience`/`resource` parameters were added: the supported target is an Okta custom authorization server with the API audience configured server-side, so client-provided audience parameters are unnecessary; `add_extra_param` support exists if a concrete provider contract ever needs them. ## Device polling behavior changes (deliberate, tested) - The first token poll now happens immediately rather than after one interval (RFC 8628 allows both). - Transient failures (HTTP 429, 5xx, `temporarily_unavailable`, network errors) now retry with exponential backoff capped at 10s instead of retrying at the fixed interval; polling never spins faster than once per second even if a server reports a zero interval. ## Security and compatibility - Issuer and discovered endpoints (and device verification URIs) still require HTTPS except explicit loopback HTTP, enforced before any crate URL type is built - Token HTTP client keeps the hardened redirect policy that refuses insecure redirect targets; regression test added - Errors never embed raw response bodies (avoids leaking tokens through parse failures); all credential types stay redacted in Debug - Transient conditions (429/5xx/`temporarily_unavailable`) remain retryable in device polling and hard errors elsewhere; refresh keeps rotation and reauthentication semantics - Existing public APIs stay source-compatible except the added `OAuthConfig.client_auth_method` field ## Tests Rust: client-auth methods across code exchange/refresh/client-credentials/device (none/basic/post), auth-method resolution and validation, transient device retries, denial/expiry, redirect rejection, malformed-response leak check, PKCE URL assertions, redaction. Python and Node: enum values, conversion, unknown-method errors, config defaults. Manual Okta validation recipe (no automated Okta credentials): create a custom authorization server with an API audience, one confidential web app (Basic) for authorization-code, one native app (PKCE, no secret), one native device app; point `issuer_url` at the custom server, set `client_auth_method` only for the POST-required case; verify token acquisition, refresh after expiry, and `x-lancedb-credential-type: oidc` against a LanceDB deployment. Never commit tenant URLs or secrets.

Replaced the closure with a `match` that propagates the validation error; behavior with an explicit `location` is unchanged (the name is not validated on that path, as before). Added tests asserting `InvalidTableName` for `create_table` and `open_table` over a set of rejected names — both panic without the fix. Full `cargo test -p lancedb --lib --features remote`: 1214 passed; clippy/fmt clean; `cargo check --workspace --all-targets` clean.

A remote catalog represents the server's root namespace, and each database is one child namespace. Create/connect return ordinary LanceDB connections, so existing table APIs work unchanged. ## Rust API `Catalog` is an object-safe async trait with `create_database`, `connect_database`, `list_databases`, and `drop_database`. Backend create/connect methods return `Arc`; the public `CatalogConnection` wraps them as `Connection` values and shares its embedding registry with those connections. `RemoteCatalog` implements the trait; `connect_catalog` is the convenience builder, available with the `remote` feature. ```rust use lancedb::catalog::{ CreateDatabaseRequest, DropDatabaseRequest, ListDatabasesRequest, }; let catalog = lancedb::connect_catalog("https://my-server.example") .api_key("my-api-key") .execute() .await?; let db = catalog.create_database( CreateDatabaseRequest::new("analytics").exist_ok(true), ).await?; let connected = catalog.connect_database("analytics").await?; let page = catalog.list_databases( ListDatabasesRequest::default().limit(20), ).await?; // page.databases: Vec; page.page_token: Option catalog.drop_database( DropDatabaseRequest::new("analytics").ignore_missing(true), ).await?; ``` Create/drop also accept a plain name for default behavior, e.g. `catalog.create_database("analytics").await?`. Existing names fail creation unless `exist_ok` is enabled; missing names fail drop unless `ignore_missing` is enabled. Drop always requires an empty database. ## Python API ```python import lancedb catalog = lancedb.connect_catalog( "https://my-server.example", api_key="my-api-key" ) db = catalog.create_database("analytics", exist_ok=True) connected = catalog.connect_database("analytics") page = catalog.list_databases(limit=20) # page.databases: list[str]; page.page_token: Optional[str] if page.page_token is not None: next_page = catalog.list_databases(limit=20, page_token=page.page_token) catalog.drop_database("analytics", ignore_missing=True) ``` `connect_catalog` returns `Catalog`; create/connect return the existing `DBConnection` API. The async equivalent is `catalog = await lancedb.connect_catalog_async(...)`, returning `AsyncCatalog`; await each of the same four methods, with create/connect returning `AsyncConnection`. ## TypeScript API ```typescript import { connectCatalog } from "@lancedb/lancedb"; const catalog = await connectCatalog("https://my-server.example", { apiKey: "my-api-key", }); const db = await catalog.createDatabase("analytics", { existOk: true }); const connected = await catalog.connectDatabase("analytics"); const page = await catalog.listDatabases({ limit: 20 }); // page.databases: string[]; page.pageToken?: string if (page.pageToken !== undefined) { const nextPage = await catalog.listDatabases({ limit: 20, pageToken: page.pageToken, }); } await catalog.dropDatabase("analytics", { ignoreMissing: true }); ``` Create/connect return the existing `Connection` API. All four methods are asynchronous. ## REST mapping All paths below are relative to the catalog endpoint. `{name}` is the logical database name encoded as one URL path component. The default namespace delimiter is `$`, so the root identifier is encoded as `%24`. | Catalog operation | Existing REST route | Request | | --- | --- | --- | | `create_database(name)` | `POST /v1/namespace/{name}/create` | `{"mode":"Create"}`; `exist_ok=true` sends `{"mode":"ExistOk"}` | | `connect_database(name)` | `POST /v1/namespace/{name}/describe` | `{}`; verifies existence before returning a scoped connection | | `list_databases(...)` | `GET /v1/namespace/%24/list` | Optional `limit` and `page_token` query parameters | | `drop_database(name)` | `POST /v1/namespace/{name}/drop` | `{"mode":"Fail","behavior":"Restrict"}`; `ignore_missing=true` changes mode to `"Skip"` | For example, database `team/search` uses `/v1/namespace/team%2Fsearch/create`. A paginated root listing can use `/v1/namespace/%24/list?limit=20&page_token=a%2Fb`. The list response retains the existing namespace wire shape, `{"namespaces":["analytics"],"page_token":"next"}`; the SDK exposes `namespaces` as `databases` and preserves the opaque continuation token. An absent or empty token ends pagination. Page limits must be between 1 and 2147483647. Create/drop accept a namespace JSON response or HTTP 204. Catalog management requests omit both `x-lancedb-database` and `x-lancedb-database-prefix`, including values supplied through static or dynamic headers. Returned database connections set `x-lancedb-database` to the exact logical name and keep independent scope. API keys, OAuth or dynamic authentication, client settings, table read consistency settings, and an optional SQL endpoint override carry over to those connections. OAuth cannot be combined with an API key or a custom header provider. For SQL through an HTTPS catalog, configure the existing SQL endpoint contract with Rust `.sql_host_override("grpc+tls://sql.example.com:10026")` or Python `sql_host_override="grpc+tls://sql.example.com:10026"`. TypeScript catalog options expose the same setting as `sqlHostOverride`. It is inherited by created/connected databases, retained by Python connection serialization, and initialized lazily when SQL is executed. Create HTTP 409 maps to `DatabaseAlreadyExists`; connect/drop HTTP 404 maps to `DatabaseNotFound`, except that `ignore_missing` suppresses a missing-database drop. Other server errors propagate. The server enforces restricted deletion; the client never requests cascading deletion. Database names preserve literal slashes as part of one name. They must be nonempty ASCII, with no control characters, surrounding whitespace, or configured namespace delimiter, and cannot be `.` or `..`. Endpoints must be HTTP(S) URLs without embedded credentials, query parameters, or fragments. ## Scope This PR adds the client API and reuses existing namespace endpoints. Local catalogs, `__catalog` storage, location generation/sanitization, and `__manifest` lifecycle support remain deferred; the Lance dependency is unchanged. The PR also runs macOS Node tests serially to avoid existing resource-contention timeouts reproduced across recent main runs. --------- Co-authored-by: Xuanwo --- .github/workflows/nodejs.yml | 2 +- docs/src/js/classes/Catalog.md | 107 ++++ docs/src/js/functions/connectCatalog.md | 32 + docs/src/js/globals.md | 4 + docs/src/js/interfaces/CatalogOptions.md | 81 +++ .../js/interfaces/ListDatabasesResponse.md | 23 + docs/src/python/python.md | 15 + nodejs/__test__/catalog.test.ts | 142 +++++ nodejs/lancedb/catalog.ts | 103 +++ nodejs/lancedb/index.ts | 7 + nodejs/src/catalog.rs | 123 ++++ nodejs/src/lib.rs | 1 + python/python/lancedb/__init__.py | 13 + python/python/lancedb/_lancedb.pyi | 24 + python/python/lancedb/catalog.py | 196 ++++++ python/python/lancedb/remote/db.py | 41 ++ python/python/tests/test_catalog.py | 140 ++++ python/src/catalog.rs | 125 ++++ python/src/error.rs | 2 + python/src/lib.rs | 3 + rust/lancedb/src/catalog.rs | 259 ++++++++ rust/lancedb/src/lib.rs | 7 + rust/lancedb/src/remote.rs | 3 + rust/lancedb/src/remote/catalog.rs | 598 ++++++++++++++++++ rust/lancedb/src/remote/client.rs | 16 +- rust/lancedb/src/remote/db.rs | 78 ++- rust/lancedb/src/remote/sql_test.rs | 62 +- 27 files changed, 2200 insertions(+), 7 deletions(-) create mode 100644 docs/src/js/classes/Catalog.md create mode 100644 docs/src/js/functions/connectCatalog.md create mode 100644 docs/src/js/interfaces/CatalogOptions.md create mode 100644 docs/src/js/interfaces/ListDatabasesResponse.md create mode 100644 nodejs/__test__/catalog.test.ts create mode 100644 nodejs/lancedb/catalog.ts create mode 100644 nodejs/src/catalog.rs create mode 100644 python/python/lancedb/catalog.py create mode 100644 python/python/tests/test_catalog.py create mode 100644 python/src/catalog.rs create mode 100644 rust/lancedb/src/catalog.rs create mode 100644 rust/lancedb/src/remote/catalog.rs diff --git a/.github/workflows/nodejs.yml b/.github/workflows/nodejs.yml index 55c050a7d..98acccf02 100644 --- a/.github/workflows/nodejs.yml +++ b/.github/workflows/nodejs.yml @@ -207,4 +207,4 @@ jobs: pnpm tsc - name: Test run: | - pnpm test + pnpm test --runInBand diff --git a/docs/src/js/classes/Catalog.md b/docs/src/js/classes/Catalog.md new file mode 100644 index 000000000..deac5e3ce --- /dev/null +++ b/docs/src/js/classes/Catalog.md @@ -0,0 +1,107 @@ +[**@lancedb/lancedb**](../README.md) • **Docs** + +*** + +[@lancedb/lancedb](../globals.md) / Catalog + +# Class: Catalog + +A remote catalog manages databases through the server's root namespace. + +## Accessors + +### uri + +```ts +get uri(): string +``` + +The root namespace endpoint. + +#### Returns + +`string` + +## Methods + +### connectDatabase() + +```ts +connectDatabase(name): Promise +``` + +Connect to an existing database by its logical name. + +#### Parameters + +* **name**: `string` + +#### Returns + +`Promise`<[`Connection`](Connection.md)> + +*** + +### createDatabase() + +```ts +createDatabase(name, options): Promise +``` + +Create a database, or open an existing database when existOk is true. + +#### Parameters + +* **name**: `string` + +* **options** = `{}` + +* **options.existOk?**: `boolean` + +#### Returns + +`Promise`<[`Connection`](Connection.md)> + +*** + +### dropDatabase() + +```ts +dropDatabase(name, options): Promise +``` + +Drop an empty database.

From a4f66afc6998c9cb557609c36848f91e3631399b Mon Sep 17 00:00:00 2001 From: Bruno Ramirez Date: Wed, 16 Sep 2026 12:54:22 -0600 Subject: [PATCH 23/74] feat(rust): add zonemap index builder (#4199) Lance supports ZoneMap scalar indexes, but the LanceDB Rust API did not expose a first-class way to request one through `Table::create_index`. Users had builders for the other scalar index families, while ZoneMap was missing from the public `Index` model and remote create-index serialization. This PR adds ZoneMap as a supported scalar index option in LanceDB. This was accomplished with the following changes: - Added `ZoneMapIndexBuilder` in `rust/lancedb/src/index/scalar.rs`. - Added `Index::ZoneMap` and `IndexType::ZoneMap`, including display/from-string aliases for `ZONEMAP` and `ZONE_MAP`. - Mapped local index creation to `ScalarIndexParams::for_builtin(BuiltinIndexType::ZoneMap)` and Lance `IndexType::ZoneMap` in `rust/lancedb/src/table/create_index.rs`. - Serialized remote create-index requests as `index_type: "ZONEMAP"` in `rust/lancedb/src/remote/table.rs`. - Added coverage for both local ZoneMap index creation and remote request serialization. Example: ```rust table .create_index(&["my_column"], Index::ZoneMap(Default::default())) .execute() .await?; ``` ### Testing Added `test_create_zonemap_index` for local index creation and extended the remote request body test matrix for `ZONEMAP`. --- rust/lancedb/src/index.rs | 15 ++++++- rust/lancedb/src/index/scalar.rs | 22 ++++++++++ rust/lancedb/src/remote/table.rs | 2 + rust/lancedb/src/table/create_index.rs | 57 +++++++++++++++++++++++++- 4 files changed, 94 insertions(+), 2 deletions(-) diff --git a/rust/lancedb/src/index.rs b/rust/lancedb/src/index.rs index c693dc056..0611f95b1 100644 --- a/rust/lancedb/src/index.rs +++ b/rust/lancedb/src/index.rs @@ -13,7 +13,10 @@ use crate::index::vector::IvfRqIndexBuilder; use crate::{DistanceType, Error, Result, job::Job, table::BaseTable}; use self::{ - scalar::{BTreeIndexBuilder, BitmapIndexBuilder, FmIndexBuilder, LabelListIndexBuilder}, + scalar::{ + BTreeIndexBuilder, BitmapIndexBuilder, FmIndexBuilder, LabelListIndexBuilder, + ZoneMapIndexBuilder, + }, vector::{ IvfHnswFlatIndexBuilder, IvfHnswPqIndexBuilder, IvfHnswSqIndexBuilder, IvfPqIndexBuilder, IvfSqIndexBuilder, @@ -54,6 +57,12 @@ pub enum Index { /// substrings of the raw bytes, unlike the tokenized [`Index::FTS`] index.

This PR gives ZoneMap its own validation helper so it can accept the broader scalar set while keeping the rest of the create-index path unchanged. --- rust/lancedb/src/table/create_index.rs | 73 +++++++++++++++++++++++++- rust/lancedb/src/utils/mod.rs | 8 +++ 2 files changed, 79 insertions(+), 2 deletions(-) diff --git a/rust/lancedb/src/table/create_index.rs b/rust/lancedb/src/table/create_index.rs index 2cc66b8cd..a5fb59b0b 100644 --- a/rust/lancedb/src/table/create_index.rs +++ b/rust/lancedb/src/table/create_index.rs @@ -30,7 +30,7 @@ use crate::index::vector::{VectorIndex, suggested_num_sub_vectors}; use crate::utils::{ resolve_lance_fts_field_path, supported_bitmap_data_type, supported_btree_data_type, supported_fm_data_type, supported_fts_data_type, supported_label_list_data_type, - supported_vector_data_type, + supported_vector_data_type, supported_zonemap_data_type, }; use super::NativeTable; @@ -260,7 +260,7 @@ impl NativeTable { ))) } Index::ZoneMap(_) => { - Self::validate_index_type(field, "ZoneMap", supported_btree_data_type)?; + Self::validate_index_type(field, "ZoneMap", supported_zonemap_data_type)?; Ok(Box::new(ScalarIndexParams::for_builtin( BuiltinIndexType::ZoneMap, ))) @@ -1252,6 +1252,75 @@ mod tests { assert_eq!(stats.distance_type, None); } + #[tokio::test] + async fn test_create_zonemap_index_on_wider_scalar_types() { + let conn = connect("memory://").execute().await.unwrap(); + let schema = Arc::new(Schema::new(vec![ + Field::new("large_text", DataType::LargeUtf8, true), + Field::new("binary", DataType::Binary, true), + Field::new("large_binary", DataType::LargeBinary, true), + ])); + let batch = RecordBatch::try_new( + schema, + vec![ + Arc::new(LargeStringArray::from(vec![ + Some("alpha"), + None, + Some("omega"), + ])) as ArrayRef, + Arc::new(BinaryArray::from(vec![ + Some(b"aa".as_slice()), + None, + Some(b"zz".as_slice()), + ])) as ArrayRef, + Arc::new(LargeBinaryArray::from(vec![ + Some(b"left".as_slice()), + None, + Some(b"right".as_slice()), + ])) as ArrayRef, + ], + ) + .unwrap(); + let table = conn + .create_table("zonemap_wider_scalar_table", batch) + .execute() + .await + .unwrap(); + + for column in ["large_text", "binary", "large_binary"] { + table + .create_index(&[column], Index::ZoneMap(ZoneMapIndexBuilder::default())) + .execute() + .await + .unwrap(); + let index_name = format!("{column}_idx"); + table + .wait_for_index(&[&index_name], Duration::from_millis(10)) + .await + .unwrap(); + } + + let index_configs = table.list_indices().await.unwrap(); + assert_eq!(index_configs.len(), 3); + for index in index_configs { + assert_eq!(index.index_type, crate::index::IndexType::ZoneMap); + } + + let null_count = table + .query() + .only_if("large_text IS NULL") + .execute() + .await + .unwrap() + .try_collect::>() + .await + .unwrap() + .iter() + .map(|b| b.num_rows()) + .sum::(); + assert_eq!(null_count, 1); + } + #[tokio::test] async fn test_create_index_nested_field_paths() { let tmp_dir = tempdir().unwrap(); diff --git a/rust/lancedb/src/utils/mod.rs b/rust/lancedb/src/utils/mod.rs index 1bfd2d042..a66e758f7 100644 --- a/rust/lancedb/src/utils/mod.rs +++ b/rust/lancedb/src/utils/mod.rs @@ -406,6 +406,14 @@ pub fn supported_btree_data_type(dtype: &DataType) -> bool { ) } +pub fn supported_zonemap_data_type(dtype: &DataType) -> bool { + supported_btree_data_type(dtype) + || matches!( + dtype, + DataType::LargeUtf8 | DataType::Binary | DataType::LargeBinary + ) +} + pub fn supported_bitmap_data_type(dtype: &DataType) -> bool { dtype.is_integer() || matches!( From 3309c71a6ebc674f34e178aaf7e00070007d766a Mon Sep 17 00:00:00 2001 From: Lance Release Date: Wed, 16 Sep 2026 20:15:06 +0000 Subject: [PATCH 26/74] =?UTF-8?q?Bump=20version:=200.40.0-beta.0=20?= =?UTF-8?q?=E2=86=92=200.40.0-beta.1?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit --- .bumpversion.toml | 2 +- Cargo.lock | 6 +++--- docs/src/java/java.md | 2 +- java/lancedb-core/pom.xml | 2 +- java/pom.xml | 2 +- nodejs/Cargo.toml | 2 +- nodejs/npm/darwin-arm64/package.json | 2 +- nodejs/npm/linux-arm64-gnu/package.json | 2 +- nodejs/npm/linux-arm64-musl/package.json | 2 +- nodejs/npm/linux-x64-gnu/package.json | 2 +- nodejs/npm/linux-x64-musl/package.json | 2 +- nodejs/npm/win32-arm64-msvc/package.json | 2 +- nodejs/npm/win32-x64-msvc/package.json | 2 +- nodejs/package.json | 2 +- python/Cargo.toml | 2 +- rust/lancedb/Cargo.toml | 2 +- 16 files changed, 18 insertions(+), 18 deletions(-) diff --git a/.bumpversion.toml b/.bumpversion.toml index 8a9eb735d..c28f65ec1 100644 --- a/.bumpversion.toml +++ b/.bumpversion.toml @@ -1,5 +1,5 @@ [tool.bumpversion] -current_version = "0.40.0-beta.0" +current_version = "0.40.0-beta.1" parse = """(?x) (?P0|[1-9]\\d*)\\.

named Secrets, bindings, and namespace addressing (#4150) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds the client half of database-scoped named Secrets: a Secret is a name and an opaque value stored by the service, and a Function binds one to the environment variable its library already reads. Secrets are addressed by a namespace path plus a name. The UDF body is unchanged and stays portable — it reads `OPENAI_API_KEY` the way it always did, and the binding is what puts a value there: ```python db.create_secret("openai-prod", os.environ["OPENAI_API_KEY"]) function = db.create_function( analyze_caption, secrets=[ EnvVarSecret(secret_name="openai-prod", env_variable="OPENAI_API_KEY") ], ) function.secret_bindings # the Secret's name, never its value ``` - `create_secret` / `alter_secret` / `list_secrets` / `describe_secret` / `drop_secret` on sync, async and remote connections, with the pyo3 binding and the Rust client behind them. Each takes `namespace_path` keyword-only, defaulting to the root. - **There is no read API, by construction rather than by policy** — no code path returns a stored credential, and `describe_secret` answers with metadata only. - `EnvVarSecret` is a pure local constructor: it contacts no server, so it cannot fail on a Secret that does not exist. It exists so that a bare string in that position — which would be a credential — is a `TypeError` rather than a plausible-looking mistake that reads identically in a diff. - `create_function(..., secrets=[...])` carries the bindings as `secret_bindings`: a list of `SecretBinding` tagged by `kind`, so a later delivery mode is a variant rather than a sibling field. The value never travels — it is resolved by the service when the Function runs, which is what lets a rotation reach columns already pinned to an older FunctionVersion. - A binding names its Secret as a `SecretReference` of `{name, namespace_path}` rather than one joined string, so no delimiter has to be excluded from every name and segment forever, and `ClientConfig.id_delimiter` cannot contradict an identity built on a fixed separator. - A root namespace is omitted from the request body rather than sent empty, so a root request is byte-identical to one from a client that predates namespaces. Tests pin it. This is the client surface the design's §4 describes; the service side lives in sophon. **Previously split across two PRs.** Namespace addressing was #4151, stacked on this one; it is folded in here so the Secret identity contract — name, namespace path, and the binding that carries both — is reviewable as one piece rather than as a shape introduced and then replaced. ## Identifier safety, merged from #4189 **#4189 is merged into this branch**, so the client half of Secrets and the guards on the identity it puts in the URL are one PR. What it added: - Components are checked where the identifier is built, before a request is constructed. `create_secret("../jobs", value)` no longer resolves to `/v1/jobs/create` and delivers a credential-bearing body to a route with none of this one's body suppression. - Each component is percent-encoded and joined by the delimiter, so nothing inside a component can end the path segment or add one. - A component may not be empty, a relative segment (`.`, `..`, and their `%2e` spellings), or the delimiter itself — the three ways a component erases a boundary the split has to recover. `["prod", ""]` joined to `prod$`, which reads back as `["prod"]`. - `$` is the only accepted `id_delimiter`, refused at client construction. `ClientConfig.id_delimiter` remains, since the identifier grammar comes from the Lance REST catalog standard, but a value that would produce identifiers no service splits the caller's way is now an error where it was written. - One `build_object_identifier` and one character set serve tables, namespaces, Secrets, Functions and materialized views. Components are checked for *addressability*, not a character set: the name's own grammar stays each object's own, so a catalog database keeps the `/` that `RemoteCatalog::validate_name` allows. ## Known shortcoming `secret_bindings` is omitted from a registration body when empty, so a client that binds nothing sends what a client without bindings sends. When a client does bind a Secret and the service does not know the field, the field is ignored: registration succeeds, the returned version carries no bindings, and the Function fails at execution with the variable unset, far from the call that asked for it. `ServerVersion` is how this codebase refuses a feature the service is too old for, and it gates five features already. It does not gate this one: it is held per table, and registering a Function is a database-level call. Noted at the field in `remote/db.rs`; wiring the gate is follow-up work. **Tests:** lancedb lib 1340 passed, `first_class_function_slice1` 9, `first_class_function_slice2` 3, plus Python tests across both slices. Rebased onto `main` after #4176 (OCI Function identity), #4191 (`.`/`..` table names) and #4195 (remote catalogs). 🤖 Generated with [Claude Code](https://claude.com/claude-code) https://claude.ai/code/session_01UfmeJ533rQDnPBkMtjerV6 --------- Co-authored-by: Claude Opus 5 (1M context) --- docs/src/js/interfaces/ClientConfig.md | 4 + docs/src/python/python.md | 4 + nodejs/__test__/catalog.test.ts | 2 +- nodejs/src/remote.rs | 3 + python/python/lancedb/__init__.py | 2 + python/python/lancedb/_lancedb.pyi | 15 + python/python/lancedb/db.py | 223 +++++- python/python/lancedb/functions.py | 112 ++- python/python/lancedb/remote/__init__.py | 5 +- python/python/lancedb/remote/db.py | 50 +- python/python/lancedb/secrets.py | 226 ++++++ python/python/tests/test_catalog.py | 2 +- .../tests/test_first_class_function_slice1.py | 48 ++ .../tests/test_first_class_function_slice2.py | 414 ++++++++++- python/src/connection.rs | 79 ++ rust/lancedb/src/connection.rs | 85 +++ rust/lancedb/src/database.rs | 45 ++ rust/lancedb/src/function.rs | 102 ++- rust/lancedb/src/lib.rs | 1 + rust/lancedb/src/remote/catalog.rs | 2 +- rust/lancedb/src/remote/client.rs | 194 ++++- rust/lancedb/src/remote/db.rs | 702 ++++++++++++++++-- rust/lancedb/src/secrets.rs | 181 +++++ rust/lancedb/src/utils/mod.rs | 137 ++-- .../tests/first_class_function_slice1.rs | 100 +++ .../tests/first_class_function_slice2.rs | 57 ++ .../v1/remote_function_job.json | 11 +- ...secret_registration_request.canonical.json | 1 + ..._function_secret_registration_request.json | 52 ++ .../v1/remote_function_version.canonical.json | 2 +- 30 files changed, 2671 insertions(+), 190 deletions(-) create mode 100644 python/python/lancedb/secrets.py create mode 100644 rust/lancedb/src/secrets.rs create mode 100644 rust/lancedb/tests/fixtures/first_class_functions/v1/remote_function_secret_registration_request.canonical.json create mode 100644 rust/lancedb/tests/fixtures/first_class_functions/v1/remote_function_secret_registration_request.json diff --git a/docs/src/js/interfaces/ClientConfig.md b/docs/src/js/interfaces/ClientConfig.md index 94cee5b5e..2b4984b8d 100644 --- a/docs/src/js/interfaces/ClientConfig.md +++ b/docs/src/js/interfaces/ClientConfig.md @@ -22,6 +22,10 @@ optional extraHeaders: Record; optional idDelimiter: string; ``` +The delimiter joining a namespace path and a name into one object +identifier. `"$"` is the only supported value, and leaving this unset is +how to get it; anything else is rejected when the connection is created. + *** ### retryConfig?

From c72931b30fa8cd6f27e2c061187a00cc21011670 Mon Sep 17 00:00:00 2001 From: Xuanwo Date: Thu, 17 Sep 2026 15:52:34 +0800 Subject: [PATCH 30/74] feat(python): add TypeSafe reranker (#4209) Adds `TypeSafeReranker`, which reranks vector, FTS, and hybrid results with the [TypeSafe System One API](https://docs.typesafe.ai/introduction). Each result is scored independently: TypeSafe reads `{"query", "document"}` and answers a yes/no (noul) question, and the probability of yes becomes `_relevance_score`. Unlike listwise LLM rerankers, the score is an absolute probability, so it is comparable across queries and can be thresholded. The question's `instructions` and `true`/`false` `criteria` are configurable, since domain-specific criteria are what make this kind of scoring work well ([TypeSafe's re-ranking cookbook](https://docs.typesafe.ai/cookbooks/rerank_typesafe)). The API takes one state per request, so the reranker sends one request per result on a thread pool bounded by `max_concurrency`. It deliberately does not use the background event loop: rerankers are called synchronously from inside the async query APIs, where `LOOP.run` would deadlock. TypeSafe scores for the same pair vary slightly between calls, so results with close scores can swap places when a search is repeated. The shared reranker test helper now takes `deterministic=False` for this case: it still checks result sizes and descending scores, but not that two identical searches return the same order. The SDK is imported only when the client is created and questions are sent as plain dicts, so the new tests run in CI with a fake client and without `typesafe-sdk` installed. The live-API test is skipped without `TYPESAFE_API_KEY`. Ranking quality has not been compared with other API rerankers. --- python/pyproject.toml | 1 + python/python/lancedb/rerankers/__init__.py | 2 + python/python/lancedb/rerankers/typesafe.py | 159 ++++++++++++++++++++ python/python/tests/test_rerankers.py | 107 ++++++++++++- 4 files changed, 266 insertions(+), 3 deletions(-) create mode 100644 python/python/lancedb/rerankers/typesafe.py diff --git a/python/pyproject.toml b/python/pyproject.toml index dc5ea603d..de84367a8 100644 --- a/python/pyproject.toml +++ b/python/pyproject.toml @@ -126,6 +126,7 @@ include = [ "python/lancedb/rerankers/util.py", "python/lancedb/rerankers/__init__.py", "python/lancedb/rerankers/voyageai.py", + "python/lancedb/rerankers/typesafe.py", "python/lancedb/rerankers/jinaai.py", "python/lancedb/rerankers/openai.py", "python/lancedb/rerankers/cross_encoder.py", diff --git a/python/python/lancedb/rerankers/__init__.py b/python/python/lancedb/rerankers/__init__.py index aef2d331e..bd906f831 100644 --- a/python/python/lancedb/rerankers/__init__.py +++ b/python/python/lancedb/rerankers/__init__.py @@ -11,6 +11,7 @@ from .jinaai import JinaReranker from .rrf import RRFReranker from .mrr import MRRReranker from .answerdotai import AnswerdotaiRerankers +from .typesafe import TypeSafeReranker from .voyageai import VoyageAIReranker from .watsonx import WatsonxReranker @@ -27,6 +28,7 @@ __all__ = [ "JinaReranker", "RRFReranker", "AnswerdotaiRerankers", + "TypeSafeReranker", "VoyageAIReranker", "MRRReranker", "WatsonxReranker", diff --git a/python/python/lancedb/rerankers/typesafe.py b/python/python/lancedb/rerankers/typesafe.py new file mode 100644 index 000000000..2da9b673c --- /dev/null +++ b/python/python/lancedb/rerankers/typesafe.py @@ -0,0 +1,159 @@ +# SPDX-License-Identifier: Apache-2.0 +# SPDX-FileCopyrightText: Copyright The LanceDB Authors + + +from concurrent.futures import ThreadPoolExecutor +from functools import cached_property +from typing import Any, Dict, Mapping, Optional + +import pyarrow as pa + +from ..util import attempt_import_or_raise +from .base import Reranker + +DEFAULT_INSTRUCTIONS = ( + "Does the document contain information that answers or directly addresses " + "the query?" +) +DEFAULT_CRITERIA = { + "true": "The document answers the query or states facts the query asks about.", + "false": "The document is off-topic, or only shares keywords or a general " + "subject with the query without addressing it.", +} +# The key TypeSafe returns the answer under.

A user who hit per-row failures still had to open a SQL session. `Table::function_errors` calls the route. The listing is table-addressed with optional job and column filters, the same addressing the SQL surface uses, so the two cannot disagree about what a table's errors are. The two non-record signals come back as their own fields rather than as rows: capped-fragment summaries, and whether the listing stopped at its limit. Local tables refuse rather than answer with an empty list. Python and Node expose the same call, with the same optional filters. --- Cargo.lock | 4 +- docs/src/js/classes/Table.md | 35 +++++ docs/src/js/globals.md | 4 + .../js/interfaces/FunctionErrorFragment.md | 42 ++++++ docs/src/js/interfaces/FunctionErrorRecord.md | 92 +++++++++++++ docs/src/js/interfaces/FunctionErrors.md | 39 ++++++ .../js/interfaces/FunctionErrorsOptions.md | 39 ++++++ docs/src/python/python.md | 6 + nodejs/__test__/remote.test.ts | 60 ++++++++ nodejs/__test__/table.test.ts | 8 ++ nodejs/lancedb/index.ts | 4 + nodejs/lancedb/table.ts | 31 +++++ nodejs/src/table.rs | 117 ++++++++++++++++ python/python/lancedb/__init__.py | 3 + python/python/lancedb/_lancedb.pyi | 29 ++++ python/python/lancedb/remote/table.py | 10 ++ python/python/lancedb/table.py | 97 +++++++++++++ python/python/tests/test_remote_db.py | 65 +++++++++ python/python/tests/test_table.py | 7 + python/src/lib.rs | 8 +- python/src/table.rs | 130 ++++++++++++++++++ rust/lancedb/src/function.rs | 95 +++++++++++++ rust/lancedb/src/remote/table.rs | 111 +++++++++++++++ rust/lancedb/src/table.rs | 67 +++++++++ 24 files changed, 1099 insertions(+), 4 deletions(-) create mode 100644 docs/src/js/interfaces/FunctionErrorFragment.md create mode 100644 docs/src/js/interfaces/FunctionErrorRecord.md create mode 100644 docs/src/js/interfaces/FunctionErrors.md create mode 100644 docs/src/js/interfaces/FunctionErrorsOptions.md diff --git a/Cargo.lock b/Cargo.lock index 0d6a28878..1d1861a59 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -5368,8 +5368,8 @@ dependencies = [ [[package]] name = "lance-geo" -version = "13.0.0-beta.3" -source = "git+https://github.com/lance-format/lance.git?tag=v13.0.0-beta.3#565808c992c3d2adf1909b9753b50a28b6bd8a19" +version = "13.0.0-beta.4" +source = "git+https://github.com/lance-format/lance.git?tag=v13.0.0-beta.4#fea665e0d96d73acd1be330ce850973ff00b7126" dependencies = [ "datafusion", "geo-traits", diff --git a/docs/src/js/classes/Table.md b/docs/src/js/classes/Table.md index dfa0a9819..a8c382c27 100644 --- a/docs/src/js/classes/Table.md +++ b/docs/src/js/classes/Table.md @@ -578,6 +578,41 @@ so this is safe to call repeatedly. *** +### functionErrors() + +```ts +abstract functionErrors(options?): Promise +``` + +The per-row errors Function refreshes recorded on this table. + +A refresh running under a skip policy records each row it skipped with +the input that failed and the error.

The hazard is narrower: a binding stores the exact Arrow fields of its inputs, outputs and assignment column, so editing one of those strands it and the table stops accepting rows. Any other column was never at risk. The guard now compares the columns a request names, a rename's target included, against the set every binding depends on, and refuses only on an intersection. Local and remote tables apply the same rule. The blanket guard stays on update and merge insert, which cannot say what they touch. --- rust/lancedb/src/remote/table.rs | 80 ++++++- rust/lancedb/src/table/computed_columns.rs | 143 +++++++++++- rust/lancedb/src/table/schema_evolution.rs | 250 +++++++++++++++++++-- 3 files changed, 446 insertions(+), 27 deletions(-) diff --git a/rust/lancedb/src/remote/table.rs b/rust/lancedb/src/remote/table.rs index 4280c7437..79bf2e354 100644 --- a/rust/lancedb/src/remote/table.rs +++ b/rust/lancedb/src/remote/table.rs @@ -3314,9 +3314,10 @@ impl BaseTable for RemoteTable { _read_columns: Option>, ) -> Result { self.check_mutable().await?; - crate::table::computed_columns::ensure_no_function_bindings_for_mutation( + crate::table::computed_columns::ensure_not_function_bound( self.schema().await?.as_ref(), "schema evolution", + crate::table::schema_evolution::new_column_names(&transforms), )?; match transforms { NewColumnTransform::SqlExpressions(expressions) => { @@ -3369,9 +3370,10 @@ impl BaseTable for RemoteTable { async fn add_computed_columns(&self, columns: &[(String, String)]) -> Result { self.check_mutable().await?; - crate::table::computed_columns::ensure_no_function_bindings_for_mutation( + crate::table::computed_columns::ensure_not_function_bound( self.schema().await?.as_ref(), "schema evolution", + columns.iter().map(|(name, _)| name), )?; // The server plans the declaration against its table schema, including // Blob v2 semantics inherited by a direct field projection. @@ -7982,8 +7984,9 @@ mod tests { assert_eq!(result.version, 8); } - #[tokio::test] - async fn test_add_function_column_allows_an_existing_binding() { + /// The fixture binding's table: `title` and `body` bound as inputs, its + /// two outputs declared, plus an unbound `spare`. + fn fixture_bound_schema() -> Schema { let binding = crate::function::FunctionBinding::from_json(include_str!( "../../tests/fixtures/first_class_functions/v1/remote_function_binding.json" )) @@ -8010,13 +8013,78 @@ mod tests { ), ) })); - let schema = Schema::new_with_metadata( + fields.push(Field::new("spare", DataType::Int32, true)); + Schema::new_with_metadata( fields, HashMap::from([( crate::table::computed_columns::FUNCTION_BINDINGS_META_KEY.to_string(), binding_metadata, )]), - ); + ) + } + + /// Only a column the binding uses is refused, and it is refused before + /// any request goes out; the rest reach the server as usual. + #[tokio::test] + async fn test_add_columns_scopes_to_the_columns_a_binding_uses() { + let table = Table::new_with_handler("my_table", |request| match request.url().path() { + "/v1/table/my_table/describe/" => http::Response::builder() + .status(200) + .body(describe_response(&fixture_bound_schema())) + .unwrap(), + "/v1/table/my_table/add_columns/" => http::Response::builder() + .status(200) + .body(r#"{"version":10}"#.to_string()) + .unwrap(), + path => panic!("Unexpected path: {path}"), + }); + table + .add_columns() + .computed("doubled", "spare * 2") + .execute() + .await + .unwrap(); + table + .add_columns() + .transform(NewColumnTransform::SqlExpressions(vec![( + "eager".into(), + "spare + 1".into(), + )])) + .execute() + .await + .unwrap(); + + let table = Table::new_with_handler("my_table", |request| match request.url().path() { + "/v1/table/my_table/describe/" => http::Response::builder() + .status(200) + .body(describe_response(&fixture_bound_schema())) + .unwrap(), + path => panic!("mutation request must not be sent: {path}"), + }); + for name in ["title", "search_text"] { + let err = table + .add_columns() + .computed(name, "1") + .execute() + .await + .unwrap_err(); + assert!(matches!(err, Error::InvalidInput { .. }), "{err:?}"); + let err = table + .add_columns() + .transform(NewColumnTransform::SqlExpressions(vec![( + name.into(), + "1".into(), + )])) + .execute() + .await + .unwrap_err(); + assert!(matches!(err, Error::InvalidInput { .. }), "{err:?}"); + } + } + + #[tokio::test] + async fn test_add_function_column_allows_an_existing_binding() { + let schema = fixture_bound_schema(); let table = Table::new_with_handler("my_table", move |request| match request.url().path() { "/v1/table/my_table/describe/" => http::Response::builder() diff --git a/rust/lancedb/src/table/computed_columns.rs b/rust/lancedb/src/table/computed_columns.rs index f87d42426..23a870b42 100644 --- a/rust/lancedb/src/table/computed_columns.rs +++ b/rust/lancedb/src/table/computed_columns.rs @@ -391,6 +391,9 @@ pub(crate) fn ensure_supported_function_metadata(schema: &ArrowSchema) -> Result Ok(()) } +/// Refuse `operation` outright on a table with a Function binding.

No local builds or tests were run. --- rust/lancedb/src/materialized_view.rs | 3 +- rust/lancedb/src/remote/db.rs | 79 +++++++++++++++++++++------ 2 files changed, 65 insertions(+), 17 deletions(-) diff --git a/rust/lancedb/src/materialized_view.rs b/rust/lancedb/src/materialized_view.rs index 94fcb5dda..39b243d49 100644 --- a/rust/lancedb/src/materialized_view.rs +++ b/rust/lancedb/src/materialized_view.rs @@ -1545,7 +1545,8 @@ impl Connection { /// /// This validates that the named resource is a materialized view rather /// than an ordinary table.

Passing `parsed.path` directly to Pillow therefore tries to open a literal `%20` path and fails. ## Testing - Added a regression test that opens an image whose local filename contains a space. - Verified the focused URI conversion behavior against the changed method. - Ruff check, formatting check, and `compileall` on both changed files.

That names shapes instead of describing a relation. A materialized view is now a relation defined by a query, stored as one canonical SQL string under a format number: ```sql SELECT columns FROM [ns.]table [, function(args) AS alias | , UNNEST(column) AS alias] [WHERE predicate] [LIMIT n] ``` Any other clause is refused at parse time. Older readers report the view as unrefreshable, the pre-format layouts still read, and a legacy view is rewritten on its next refresh that commits, rebuilt only where its raw text meant something else under lance's parser. A Function in FROM position yields one row per element it returns, as a table function does in any dialect. The server stages its list output in a hidden table and records that binding beside the query, which stays as the user wrote it; refresh scans the staging and unnests the column, the same operator as UNNEST over a list column the table already holds. Row ids repeat per element, so eviction and incremental append are unchanged.

Function binding when its output columns are dropped (#4231) Dropping a column a Function binding writes was refused outright, which left a bad declaration unrecoverable: the binding is immutable, there is no rebind, and so the column could never be filled again. A drop that names every output of a binding now retires it instead. A binding lives in three places -- the envelope in schema metadata, a `computed_column.*` marker on each output field, and the columns themselves -- and readers cross-check the first two, so removing one and leaving the others is a table that refuses every write. The retirement therefore commits in two steps, each landing a state that stands on its own: one `UpdateConfig` rewrites the envelope and clears the markers together, leaving the outputs as ordinary columns holding their last values, and the drop follows. Interrupted between them, the columns are still there to be dropped again. Folding the metadata into the drop's own `Project` was the obvious alternative and does not work: the transaction proto records `Project` as fields alone, so the edit would survive only in the writer's memory. Naming one output of a multi-output binding is refused and names the missing siblings, since one refresh writes them in one commit. A multi-output binding's hidden `__function_assignment_*` column goes with it. Inputs stay protected while a surviving binding reads them, and drop in the request that retires the last one. --- rust/lancedb/src/table/computed_columns.rs | 190 ++++++++- rust/lancedb/src/table/schema_evolution.rs | 447 +++++++++++++++++++-- 2 files changed, 596 insertions(+), 41 deletions(-) diff --git a/rust/lancedb/src/table/computed_columns.rs b/rust/lancedb/src/table/computed_columns.rs index 23a870b42..679928cd3 100644 --- a/rust/lancedb/src/table/computed_columns.rs +++ b/rust/lancedb/src/table/computed_columns.rs @@ -418,23 +418,18 @@ pub(crate) fn ensure_not_function_bound>( touched: impl IntoIterator, ) -> Result<()> { ensure_supported_function_metadata(schema)?; - let mut protected = BTreeSet::new(); - for binding in function_bindings(schema)? { - for input in binding.inputs() { - protected.insert(field_root(&input.field_path)?); - } - protected.extend( - binding - .outputs() - .iter() - .map(|output| output.output_name.clone()), - ); - protected.extend( - binding - .assignment() - .map(|assignment| assignment.output_name.clone()), - ); - } + ensure_not_bound_by(&function_bindings(schema)?, operation, touched) +} + +/// [`ensure_not_function_bound`] against an explicit set of bindings, for a +/// caller that is retiring some of the schema's own in the same operation and +/// must be checked against what survives it. +pub(crate) fn ensure_not_bound_by>( + bindings: &[FunctionBinding], + operation: &str, + touched: impl IntoIterator, +) -> Result<()> { + let protected = protected_roots(bindings)?; if protected.is_empty() { return Ok(()); } @@ -452,6 +447,129 @@ pub(crate) fn ensure_not_function_bound>( Ok(()) } +/// Every column `bindings` depend on, inputs taken at their root. +fn protected_roots(bindings: &[FunctionBinding]) -> Result> { + let mut protected = BTreeSet::new(); + for binding in bindings { + for input in binding.inputs() { + protected.insert(field_root(&input.field_path)?); + } + protected.extend( + binding + .outputs() + .iter() + .map(|output| output.output_name.clone()), + ); + protected.extend( + binding + .assignment() + .map(|assignment| assignment.output_name.clone()), + ); + } + Ok(protected) +} + +/// What a drop must do besides removing columns, so that the Function +/// bindings it covers are retired rather than stranded. +#[derive(Debug, Default)] +pub struct FunctionUnbinding { + /// The bindings the drop leaves in place.

Previously this raised an error. This achieves parity with local client. Server-side implementation is already complete. `RemoteTable::add_columns` matched only `SqlExpressions` and refused everything else, so `add_columns(pa.Field | List[pa.Field] | pa.Schema)` reached a remote table as `NotSupported`. Every layer above was already in place: the Python and Node surfaces accept a schema, both bindings build `NewColumnTransform::AllNulls` from it, and the Function-binding guard already reads that variant's column names. Only the arm that turns it into a request was missing. Send the schema as an Arrow IPC schema message under `application/vnd.apache.arrow.stream`, which is what the server takes. It is also the only encoding that round-trips a field whole: the JSON type representations either hide decimal precision in a length field or drop a timestamp's unit and timezone. With no JSON envelope the branch rides the query string, as it does for the other binary-bodied endpoints. The response handling is now shared by both arms rather than living inside the SQL one, so the new path gets the same schema-cache invalidation, write-version tracking, and old-server empty-body fallback. Also widen the sync `RemoteTable.add_columns` annotation to match `Table.add_columns`. It delegates to the async table, so a schema already worked at runtime; only the signature and its docs disagreed.

Restore the repository's release profile (`fat` LTO, 1 codegen unit) by removing the Windows-only `thin`/16 overrides introduced in #3716. Keep `rust-lld` as the linker. This recovers wheel-size headroom at the cost of the longer fat-LTO build. The already-published 0.39.0 Windows wheel was recovered separately by recompressing the original artifact; this change addresses the build configuration for future releases. Fixes #4239. ### Windows size comparison Built the same v0.38.0 source (`8c68e0c619f2b1febe92e51a29d72c968d24a5c9`) twice on one AWS `m7i.4xlarge` Windows Server 2025 machine, changing only the LTO/codegen-unit overrides: | Artifact | thin LTO / 16 units | fat LTO / 1 unit | | --- | ---: | ---: | | Installable Windows wheel | 104,129,447 bytes (99.31 MiB) | 73,875,399 bytes (70.45 MiB) | | Uncompressed native module | 309,969,408 bytes (295.61 MiB) | 206,609,408 bytes (197.04 MiB) | The thin/16 configuration increased wheel size by **40.95%** and native-module size by **50.03%** relative to fat/1. The compressed native module accounts for all but 3 bytes of the wheel increase. Both builds used Rust 1.97.0, maturin 1.12.4, Python 3.13.5, MSVC 14.44.35207, Windows SDK 10.0.26100.0, rust-lld, static CRT, default features, and `maturin build --release --strip --locked --verbose`. They ran sequentially with separate empty target directories and identical locked third-party dependencies. The tag's stale workspace package versions were normalized once before both builds. This controlled pair used VS2022 Build Tools; the historical GitHub runner used VS2026. Both wheels passed ZIP/RECORD integrity checks and installed successfully. Native smoke checks covered import, database creation, row count, nearest-vector query, and reopening the database. This establishes the combined configuration effect; it does not isolate LTO mode from codegen-unit count or establish a runtime-performance difference. The figures above are the v0.38.0 reproduction, **not measurements of this PR head**. The existing PyPI Publish pull-request workflow rebuilds the current revision without publishing; its result is pending. Workflow validation passed with `actionlint -shellcheck=`. Full actionlint reports the same three pre-existing ShellCheck diagnostics in the unchanged repository-selection step as on `main`. --- .github/workflows/pypi-publish.yml | 8 ++------ 1 file changed, 2 insertions(+), 6 deletions(-) diff --git a/.github/workflows/pypi-publish.yml b/.github/workflows/pypi-publish.yml index b80c1b019..5f45ba68c 100644 --- a/.github/workflows/pypi-publish.yml +++ b/.github/workflows/pypi-publish.yml @@ -129,12 +129,8 @@ jobs: # link.exe is single-threaded and the long pole on Windows builds.

It needs `lance-namespace-impls/rest`, not the REST *server* adapter. `RestAdapter` is only used by `cfg(test)` integration tests that stand up an in-process server. Enabling `rest-adapter` on the production `remote` feature pulled that server stack, including Axum 0.7, into default Python wheels. This keeps `rest` on `remote` and moves `rest-adapter` to a `lance-namespace-impls` dev-dependency so those tests still compile and run. Cargo resolver=2 does not leak the extra feature into `lancedb-python`. ## Measurement Paired `maturin build --release --strip --target aarch64-apple-darwin --features fp16kernels` wheels. Source was `3be29228` plus this Cargo.toml change, which is this PR's tree (`878b2ae5` on `3be29228`). Same toolchain, profile, and packaging flags; only `rest-adapter` moved. | Artifact | Before | After | Delta | | --- | ---: | ---: | ---: | | Compressed wheel | 64,685,664 | 63,824,281 | −861,383 (−1.33%) | | `_lancedb.abi3.so` uncompressed | 148,255,440 | 146,275,936 | −1,979,504 (−1.34%) | This is macOS arm64, not Windows.

A view query now takes `GROUP BY expr, ...` with aggregate projections, planned and executed by DataFusion over the lance scan. A group spans fragments, so a grouped view is recomputed in full whenever its source changes; each row's provenance is its group's smallest source row id.

From 814de30c5a16416382f4affdc3b2ae8ade46369f Mon Sep 17 00:00:00 2001 From: Jack Ye Date: Tue, 22 Sep 2026 09:54:23 -0700 Subject: [PATCH 50/74] feat: return a cleanup job from drop_function (#4237) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Dropping a Function can leave its content to a server-side cleanup job, so the name drop and the content deletion become separate events a caller may want to wait on. `drop_function_async` returns the unbind result alongside a `Job` for the cleanup, the same shape `drop_table_async` and `drop_materialized_view_async` already use: a `202` carries the job id, and a `200` — an inline deletion, or a name that was not bound — yields an already-finished job with no id. A `202` without a usable job id is rejected rather than silently reported as finished. `drop_function` keeps its `bool` result and now delegates, so nothing changes for callers that do not care when the content goes. Available on `Connection` in Rust and on both the sync and asyncio Python connections. --- python/python/lancedb/_lancedb.pyi | 3 ++ python/python/lancedb/db.py | 44 +++++++++++++--- python/python/lancedb/remote/db.py | 6 +++ python/src/connection.rs | 15 ++++++ rust/lancedb/src/connection.rs | 16 ++++++ rust/lancedb/src/database.rs | 12 +++++ rust/lancedb/src/remote/db.rs | 81 +++++++++++++++++++++++++++++- 7 files changed, 169 insertions(+), 8 deletions(-) diff --git a/python/python/lancedb/_lancedb.pyi b/python/python/lancedb/_lancedb.pyi index 7c6611608..6d873850d 100644 --- a/python/python/lancedb/_lancedb.pyi +++ b/python/python/lancedb/_lancedb.pyi @@ -153,6 +153,9 @@ class Connection(object): async def get_function(self, name: str, version: str) -> str: ... async def list_functions(self) -> List[str]: ... async def drop_function(self, name: str, version: str) -> bool: ... + async def drop_function_async( + self, name: str, version: str + ) -> Tuple[bool, Job]: ... async def create_secret( self, name: str, value: str, namespace_path: Optional[List[str]] = None ) -> None: ... diff --git a/python/python/lancedb/db.py b/python/python/lancedb/db.py index d17e897cf..b0db22532 100644 --- a/python/python/lancedb/db.py +++ b/python/python/lancedb/db.py @@ -18,6 +18,7 @@ from typing import ( Literal, Optional, Sequence, + Tuple, Union, ) from uuid import UUID @@ -828,12 +829,26 @@ class DBConnection(EnforceOverrides): ) def drop_function(self, name: str, *, version: str) -> bool: - """Remove the current Function name binding from the remote catalog. + """Drop a Function name and the object it was bound to. - The requested version must exist in the currently named object. - Object history and existing computed-column references are retained. - Returns True when the name was removed and False when it was absent. - Local connections raise NotImplementedError. + The requested version must exist in the currently named object.

Wed, 23 Sep 2026 02:36:11 +0530 Subject: [PATCH 53/74] fix(python): convert objects for JSON fields (#4211) ## Summary Closes: #4060 - Convert Python dict/list objects to JSON strings during ingestion. - Support JSON fields nested inside structs and lists. - Cover `add` and `merge_insert` JSON ingestion paths. - Add regression coverage for nested struct and list JSON fields. ## Testing - `git diff --check` - Python compilation passed. - Focused pytest was attempted but could not complete because the native extension build stalled during `uv` bootstrap. ---

00:09:40 -0700 Subject: [PATCH 54/74] feat: add view CRUD APIs (#4236) A view is a named query a database stores and plans on every read. It holds no rows, which is the whole difference from a materialized view. ## API | Verb | Route | | --- | --- | | `create_view(name, query, namespace_path)` | `POST /v1/view/{id}/create` | | `describe_view(name, namespace_path)` | `POST /v1/view/{id}/describe` | | `drop_view(name, namespace_path)` | `POST /v1/view/{id}/drop` | | `list_views(namespace_path)` | `GET /v1/namespace/{id}/view/list` | On `Connection` and the `Database` trait, with the remote client, Python (sync and async) and Node bindings. Local databases return `NotSupported`: the server side is Sophon's, where a view is an object of the database manifest. `ViewDescription` carries the defining query, the database *and namespace path* unqualified names in it resolve against, and the schema the query resolved to. `create_view` returns one, so a caller has the schema without a second call. Both defaults travel with the view because it outlives the session that declared it: the server re-plans the stored query on every read, so a reader resolving an unqualified name against its own defaults would read a different table. `default_namespace_path` crosses the wire as `default_namespace`, a path like `namespace`, absent for the root. There is no replace: a name already taken is an error, and changing a view is a drop followed by a create, each authorized against what it actually touches. Querying a view stays SQL's job. There are no rows behind a view, so there is no `open_view` returning a `Table`. --- docs/src/js/classes/Connection.md | 95 +++++++ docs/src/js/globals.md | 1 + docs/src/js/interfaces/ViewDescription.md | 78 ++++++ docs/src/python/python.md | 4 + nodejs/__test__/remote.test.ts | 61 +++++ nodejs/lancedb/connection.ts | 67 +++++ nodejs/lancedb/index.ts | 1 + nodejs/lancedb/view.ts | 48 ++++ nodejs/src/connection.rs | 83 ++++++ python/python/lancedb/__init__.py | 2 + python/python/lancedb/_lancedb.pyi | 12 + python/python/lancedb/db.py | 141 +++++++++++ python/python/lancedb/remote/db.py | 25 ++ python/python/lancedb/view.py | 40 +++ python/python/tests/test_remote_db.py | 54 ++++ python/src/connection.rs | 88 ++++++- rust/lancedb/src/connection.rs | 94 ++++++- rust/lancedb/src/database.rs | 36 +++ rust/lancedb/src/lib.rs | 1 + rust/lancedb/src/remote/db.rs | 291 +++++++++++++++++++++- rust/lancedb/src/utils/mod.rs | 21 ++ rust/lancedb/src/view.rs | 44 ++++ 22 files changed, 1283 insertions(+), 4 deletions(-) create mode 100644 docs/src/js/interfaces/ViewDescription.md create mode 100644 nodejs/lancedb/view.ts create mode 100644 python/python/lancedb/view.py create mode 100644 rust/lancedb/src/view.rs diff --git a/docs/src/js/classes/Connection.md b/docs/src/js/classes/Connection.md index d46d414d3..75af5102e 100644 --- a/docs/src/js/classes/Connection.md +++ b/docs/src/js/classes/Connection.md @@ -319,6 +319,38 @@ Creates a new Table and initialize it with new data. *** +### createView() + +```ts +abstract createView( + name, + query, + namespacePath?): Promise +``` + +Create a view: a named query the database plans on every read. + +The query is planned once, at creation, so one that cannot be planned is +rejected now rather than at the first read.

This adds initialization to the canonical wire model without changing a Function's identity: - `FunctionSignature.initialization` lists the fields of the row, in order. It is omitted when empty, so existing signatures and FunctionVersion hashes are unchanged. - `FunctionApplication.initialization` carries a binding's values as JSON. The service validates them against the Function's fields and re-encodes them as Arrow, so this JSON is transport only and never hashed; that is why floats are accepted here while column-input literals keep the Slice 1 domain. - `FunctionBinding.initialization` is the validated one-row Arrow IPC stream (base64) that every instance of the binding is created with. Values belong to the binding, so one Function version can back several columns with different values. - The binding-shape check that guards schema mutations accepts the new field; without it a table holding an initialized binding refused further declarations. Rust and Python share new canonical goldens for an initialized application and binding. The authoring side (class `@udf`, initialization arguments, shipped helper code) is the stacked PR on top of this one. --- python/python/lancedb/functions.py | 21 +++++ .../tests/test_first_class_function_slice1.py | 41 +++++++++ rust/lancedb/src/function.rs | 87 +++++++++++++++++++ rust/lancedb/src/table/computed_columns.rs | 12 +++ .../tests/first_class_function_slice1.rs | 23 +++++ ...alized_function_application.canonical.json | 1 + ...mote_initialized_function_application.json | 37 ++++++++ ...nitialized_function_binding.canonical.json | 1 + .../remote_initialized_function_binding.json | 61 +++++++++++++ 9 files changed, 284 insertions(+) create mode 100644 rust/lancedb/tests/fixtures/first_class_functions/v1/remote_initialized_function_application.canonical.json create mode 100644 rust/lancedb/tests/fixtures/first_class_functions/v1/remote_initialized_function_application.json create mode 100644 rust/lancedb/tests/fixtures/first_class_functions/v1/remote_initialized_function_binding.canonical.json create mode 100644 rust/lancedb/tests/fixtures/first_class_functions/v1/remote_initialized_function_binding.json diff --git a/python/python/lancedb/functions.py b/python/python/lancedb/functions.py index 8c6864cc3..21c8a31e0 100644 --- a/python/python/lancedb/functions.py +++ b/python/python/lancedb/functions.py @@ -256,8 +256,16 @@ class SecretBinding(_RemoteValue): class FunctionSignature(_RemoteValue): + """Ordered inputs, output, and initialization fields of a Function. + + ``initialization`` lists the fields of the single row each Function + instance is created with.

+} From 5538bdb9ff1b6bbfaf77daea9c963ca46a841ae0 Mon Sep 17 00:00:00 2001 From: Wyatt Alt Date: Wed, 23 Sep 2026 09:13:17 -0700 Subject: [PATCH 57/74] feat: refresh an ivf-grouped materialized view in units (#4232) A grouped view's refresh runs its whole aggregate in one process, so a view grouped by ivf_partition(col) over a large table is bounded by a single worker however many workers a deployment has. The IVF index already holds each partition's row ids, so the aggregate splits along the index without a shuffle: every partition's groups are computed from its own rows alone. plan_grouped_refresh names the units (one per index partition plus one for the rows the index cannot place) and the source version they read; write_grouped_unit computes one unit's groups from the index's row ids, plus the rows of fragments the index has not covered, assigned in place, and writes them as uncommitted fragments; commit_grouped_refresh replaces the view's rows with every unit's fragments in one Update. The split has to publish what the single-pass refresh would. A unit applies the view's predicate in its own query, because neither the indexed take nor the fragment scan filters the way a lance scan does. An index that does not say which fragments it covers has unknown coverage, not empty, so it yields no plan at all and the caller refreshes in one pass rather than reading those rows twice. Each result names its unit, its plan and the view incarnation it was computed for -- two views of one shape reach the same counters, and fragments written into one dataset are not publishable into another -- and the commit publishes the plan's units exactly once each or nothing. The commit lands on the planned generation or is refused: lance rebases this Update over a concurrent append rather than rejecting it, so the version it actually landed on is checked, as the single-pass rebuild already does. What holds every unit to one index is the source version the plan pins: indices live in the source manifest, so a rebuild lands in a version the units never read. Within that version a segment's postings can still outlive its ownership -- a column rewrite attaches a new file and takes the fragment out of the segment's bitmap without dropping its rows from the posting lists -- so a unit keeps a segment's rows only while it holds their fragment, and reads the rest from the scan. The split is the grouping only where the index assigns by its own centroids. lance also builds an index from precomputed partitions, and records nowhere that it did, so a posting list can hold a row that ivf_partition puts elsewhere -- that row's group would then be aggregated in its own unit as well and published twice, since concatenated fragments cannot merge two halves of a group. The plan samples each partition and yields no units when they disagree, every unit proves the rows it took before grouping them, and the commit refuses a unit that wrote more than the single group its key allows. --- rust/lancedb/src/materialized_view.rs | 63 + rust/lancedb/src/materialized_view/grouped.rs | 181 ++- .../src/materialized_view/grouped_units.rs | 1334 +++++++++++++++++ rust/lancedb/src/materialized_view/refresh.rs | 38 +- 4 files changed, 1566 insertions(+), 50 deletions(-) create mode 100644 rust/lancedb/src/materialized_view/grouped_units.rs diff --git a/rust/lancedb/src/materialized_view.rs b/rust/lancedb/src/materialized_view.rs index c4456dbe1..430750a00 100644 --- a/rust/lancedb/src/materialized_view.rs +++ b/rust/lancedb/src/materialized_view.rs @@ -10,7 +10,70 @@ //! plain table.

Remote Python Functions could not share helper code, take typed parameters, or keep per-process state: helpers became `from import ...` lines a worker cannot resolve, every parameter was an `env=` string, and state had to be stashed on imported modules. MMLB's OpenAI preset shows the cost — 24 env vars, a 302-line callable, and a rate limiter duplicated between the scalar and batch variants, one of which never constructed it (ENT-2516). **Class Functions.** `@udf` accepts a class. Each remote instance runs `__init__` once, calls `__call__` for every row or batch it processes (row or batch mode is inferred from annotations as before), and calls `close()` once if defined. Calling the definition locally constructs the class, so unit tests stay ordinary. **Initialization.** The annotated `__init__` parameters become the Function's initialization fields. A binding passes their values beside its column inputs: `fn(text=col("body"), model="small", dimensions=512)`. Values are constants of that binding; another column can bind the same Function version with other values. Types are limited to booleans, integers, floats, strings, and lists or structs of them, which have one unambiguous JSON and SQL spelling. A parameter with a default may be omitted; a null value then takes the default. Initialization and input names must be disjoint because both are keyword arguments of one call. Secrets stay on `EnvVarSecret`. **Helper code.** `code=[package, ...]` ships top-level modules or packages as Python source in a `python_bundle` artifact (a canonical JSON object of path → source), imported normally on the worker. Changing a helper changes the artifact digest and so the Function version; the environment from `pip`/`conda` is reused. Functions and classes defined in `__main__` (notebook cells, scripts) are packaged by source, recursively and dependencies first. An import of a module that lives in a local source tree, is not shipped with `code=`, and names no declared package is now rejected at registration instead of failing on the worker. Closures, lambdas, and nested definitions are still rejected, with the reason. A Function without these features packages byte-identically to before (`python_callable`, same digest, no `initialization` on the wire). Class sources are located through a method's code object, because `inspect.getsource` cannot find a class defined in a notebook cell or doctest. The packaging contract is documented on `udf`. Sophon changes that build and execute these artifacts are in lancedb/sophon; they were verified end to end on a Linux local server (registration → REST, SQL, and materialized-view bindings with different initialization → refresh → query, one construction per instance). --- python/python/lancedb/functions.py | 812 +++++++++++++++--- .../tests/test_first_class_function_slice1.py | 2 +- .../python/tests/test_function_packaging.py | 521 +++++++++++ 3 files changed, 1201 insertions(+), 134 deletions(-) create mode 100644 python/python/tests/test_function_packaging.py diff --git a/python/python/lancedb/functions.py b/python/python/lancedb/functions.py index 21c8a31e0..380625f57 100644 --- a/python/python/lancedb/functions.py +++ b/python/python/lancedb/functions.py @@ -20,6 +20,7 @@ import importlib import inspect import symtable import json +import linecache import math import re import sys @@ -367,14 +368,20 @@ class FunctionVersion(_RemoteValue): metadata: Mapping[str, str] disabled: bool - def __call__(self, **inputs: Any) -> FunctionApplication: + def __call__(self, **arguments: Any) -> FunctionApplication: """Bind this exact version to named table columns.

In those runs dependency compilation finishes after ~26 minutes and the `lancedb` crate compile + fat-LTO step was still running after 63 minutes. Move the job to the org's `windows-2025-8x-x64` larger runner and raise the timeout to 150 minutes. Fat LTO stays, since the thin-LTO wheel exceeds PyPI's 100 MiB limit. The final fat-LTO step is largely single-threaded, so the gain from 8 cores is mainly in the parallel dependency phase plus faster/larger hardware; the PR run of this workflow is the first measurement of fat LTO on this runner. --- .github/workflows/pypi-publish.yml | 11 +++++++---- 1 file changed, 7 insertions(+), 4 deletions(-) diff --git a/.github/workflows/pypi-publish.yml b/.github/workflows/pypi-publish.yml index 5f45ba68c..4f883aec1 100644 --- a/.github/workflows/pypi-publish.yml +++ b/.github/workflows/pypi-publish.yml @@ -21,7 +21,7 @@ permissions: contents: read # Without this, a force-push to a PR leaves the previous run going -- including -# a ~74 minute Windows job and a billed arm64 wheel build. +# a long fat-LTO Windows job and a billed arm64 wheel build. concurrency: group: ${{ github.workflow }}-${{ github.event.pull_request.number || github.ref }} cancel-in-progress: true @@ -123,8 +123,11 @@ jobs: path: target/wheels/lancedb-*.whl if-no-files-found: error windows: - timeout-minutes: 90 - runs-on: windows-latest + # The fat-LTO build of the `lancedb` crate does not finish within 90 minutes + # on the 4-core standard runner, so use the 8-core larger runner with extra + # headroom. + timeout-minutes: 150 + runs-on: windows-2025-8x-x64 env: # link.exe is single-threaded and the long pole on Windows builds.

Objects without enumerable fields produced no field paths, so schema matching dropped their columns before Arrow or blob conversion. Blob instances with own fields were mistaken for struct fields. ## Fix Walk only nonempty plain records as structs. Reject unsupported object values in scalar fields, nested structs, and list elements with the field path and row number. Preserve the object types already passed through to Arrow. Support for converting these new input types is tracked in #4270. Nested class instances with enumerable fields previously became structs; this change rejects them and is labeled `breaking-change`. ## Validation - `pnpm build` - `pnpm lint` - `pnpm test __test__/arrow.test.ts __test__/blob.test.ts __test__/table.test.ts --runInBand --silent` (626 passed) - `pnpm run docs` Fixes #4269 --------- Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com> --- nodejs/__test__/arrow.test.ts | 97 +++++++++++++++++++++++++++++++++++ nodejs/__test__/blob.test.ts | 21 ++++++++ nodejs/__test__/table.test.ts | 17 ++++++ nodejs/lancedb/schema.ts | 58 +++++++++++++++++---- 4 files changed, 184 insertions(+), 9 deletions(-) diff --git a/nodejs/__test__/arrow.test.ts b/nodejs/__test__/arrow.test.ts index 6c1d5ecba..df02b4936 100644 --- a/nodejs/__test__/arrow.test.ts +++ b/nodejs/__test__/arrow.test.ts @@ -601,6 +601,103 @@ describe.each([arrow15, arrow16, arrow17, arrow18])( );

Both PyO3 methods entered `block_on`, which panics when GC runs on a LanceDB Tokio worker. ## Fix Track Python blob handle closure atomically so `closed` is synchronous. `close()` marks the handle closed immediately and, when called on a Tokio thread, schedules the underlying async cleanup without blocking that thread. Reads and seeks after close fail immediately; ordinary callers still wait for cleanup. ## Validation - Rebuilt the Python extension with `uv run --extra tests --extra dev maturin develop --extras tests,dev`. - Ran the blob test file and remote blob handle test: 69 passed, 1 skipped. - Ran `cargo fmt --all`, `ruff format .`, and `ruff check .`.

It now verifies a write through the independent handle succeeds. - `cargo test --quiet --features remote -p lancedb --lib remote::db::tests` (90 passed) - `cargo check --quiet --features remote --tests --examples` - `cargo clippy --quiet --features remote --tests --examples` - `cargo fmt --all` Fixes #4296 Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com> --- rust/lancedb/src/remote/db.rs | 107 ++++++++++++++++++++++++---------- 1 file changed, 76 insertions(+), 31 deletions(-) diff --git a/rust/lancedb/src/remote/db.rs b/rust/lancedb/src/remote/db.rs index 893c584e1..ad4a1781b 100644 --- a/rust/lancedb/src/remote/db.rs +++ b/rust/lancedb/src/remote/db.rs @@ -216,7 +216,8 @@ impl RemoteDatabaseOptionsBuilder { #[derive(Debug)] pub struct RemoteDatabase { client: RestfulLanceDbClient, - table_cache: Cache>>, + // Cache existence and server capabilities, not mutable per-handle table state. + table_cache: Cache, uri: String, /// Headers to pass to the namespace client for authentication namespace_headers: HashMap, @@ -1371,16 +1372,9 @@ impl Database for RemoteDatabase { }; for table in &tables { - let table_identifier = build_table_identifier(table, &request.namespace_path)?; + build_table_identifier(table, &request.namespace_path)?; let cache_key = build_cache_key(table, &request.namespace_path); - let remote_table = Arc::new(RemoteTable::new( - self.client.clone(), - table.clone(), - request.namespace_path.clone(), - table_identifier.clone(), - version.clone(), - )); - self.table_cache.insert(cache_key, remote_table).await; + self.table_cache.insert(cache_key, version.clone()).await; } Ok(tables) } @@ -1407,16 +1401,9 @@ impl Database for RemoteDatabase { // Cache the tables for future use let namespace_vec = namespace_parts.to_vec(); for table in &response.tables { - let table_identifier = build_table_identifier(table, &namespace_vec)?; + build_table_identifier(table, &namespace_vec)?; let cache_key = build_cache_key(table, &namespace_vec); - let remote_table = Arc::new(RemoteTable::new( - self.client.clone(), - table.clone(), - namespace_vec.clone(), - table_identifier.clone(), - version.clone(), - )); - self.table_cache.insert(cache_key, remote_table).await; + self.table_cache.insert(cache_key, version.clone()).await; } Ok(response) @@ -1484,9 +1471,9 @@ impl Database for RemoteDatabase { request.name.clone(), request.namespace_path.clone(), table_identifier, - version, + version.clone(), )); - self.table_cache.insert(cache_key, table.clone()).await; + self.table_cache.insert(cache_key, version).await; Ok(table) } @@ -1526,9 +1513,9 @@ impl Database for RemoteDatabase { request.target_table_name.clone(), request.target_namespace_path.clone(), table_identifier, - version, + version.clone(), )); - self.table_cache.insert(cache_key, table.clone()).await; + self.table_cache.insert(cache_key, version).await; Ok(table) } @@ -1537,10 +1524,17 @@ impl Database for RemoteDatabase { let identifier = build_table_identifier(&request.name, &request.namespace_path)?; let cache_key = build_cache_key(&request.name, &request.namespace_path); - // We describe the table to confirm it exists before moving on. - if let Some(table) = self.table_cache.get(&cache_key).await { - Ok(table.clone()) + // Every open gets its own checkout, schema cache, and freshness state. + if let Some(version) = self.table_cache.get(&cache_key).await { + Ok(Arc::new(RemoteTable::new( + self.client.clone(), + request.name, + request.namespace_path, + identifier, + version, + ))) } else { + // Describe the table to confirm it exists before moving on. let req = self .client .post(&format!("/v1/table/{}/describe/", identifier)); @@ -1550,13 +1544,12 @@ impl Database for RemoteDatabase { let rsp = self.client.check_response(&request_id, rsp).await?; let version = parse_server_version(&request_id, &rsp)?; let describe_body = rsp.text().await.ok(); - let table_identifier = build_table_identifier(&request.name, &request.namespace_path)?; let table = Arc::new(RemoteTable::new( self.client.clone(), request.name.clone(), request.namespace_path.clone(), - table_identifier, - version, + identifier, + version.clone(), )); // This describe already carries the schema, so hand it to the table // instead of making the first schema read fetch it again.

That is deliberately **different** from `drop_materialized_view` and `drop_function`, which return as soon as the name is unbound and document that content may still be deleting. The view API is the newer one, and waiting is the semantic worth having; the other two are left alone rather than changing behaviour already released. ## Surfaces `Database` trait, the remote client, `Connection`, and the Python and Node bindings — matching where `drop_materialized_view_async` is already exposed. Four client tests cover the accepted case reporting its job id, the nothing-bound case reporting a finished job, a `202` without a usable `job_id`, and an unexpected success status. --- docs/src/js/classes/Connection.md | 29 ++++++++++- nodejs/__test__/remote.test.ts | 31 ++++++++++++ nodejs/lancedb/connection.ts | 18 ++++++- nodejs/src/connection.rs | 19 ++++++- python/python/lancedb/_lancedb.pyi | 3 ++ python/python/lancedb/db.py | 50 ++++++++++++++++-- python/python/lancedb/remote/db.py | 7 +++ python/src/connection.rs | 17 +++++++ python/src/runtime.rs | 11 ++-- rust/lancedb/src/connection.rs | 31 +++++++++++- rust/lancedb/src/database.rs | 9 +++- rust/lancedb/src/remote/db.rs | 81 +++++++++++++++++++++++++++++- 12 files changed, 286 insertions(+), 20 deletions(-) diff --git a/docs/src/js/classes/Connection.md b/docs/src/js/classes/Connection.md index 75af5102e..a51fb986a 100644 --- a/docs/src/js/classes/Connection.md +++ b/docs/src/js/classes/Connection.md @@ -557,9 +557,10 @@ on the returned job to know when cleanup has finished. abstract dropView(name, namespacePath?): Promise ``` -Drop the view named `name`. +Drop the view named `name` and wait for its definition to be deleted. -The tables it reads are untouched: a view holds no rows of its own. +The tables it reads are untouched: a view holds no rows of its own.

Default `batch_size=1` preserves the existing payload. Each batched question sees only its document and the shared query; instructions/criteria stay unchanged. Prompts referencing `state.document` need adaptation. Concurrency still limits requests; retries remain SDK-managed. Batch-local IDs and ordered results preserve duplicate documents; invalid IDs/probabilities raise without fallback. Validation: **124 automated tests passed**, plus live search integrations in both modes. A **100-query live subset test of the initial implementation** (6,851 candidate pairs; `jev-1.13.0`, SDK 0.7.1, concurrency 32) passed: unbatched/batched calls **6,851/199**, median **877/351 ms**, p95 **9,446/598 ms**. Hybrid Hit@5/Hit@10 was **83%/89% vs 84%/90%**; vector/FTS results and exact configuration are in the [test report](https://github.com/lancedb/lancedb/blob/typesafe-request-batching/python/benchmarks/typesafe_batching.md). Ruff and MkDocs passed. The simplified batching flow also passed a fresh four-query live check: 292 candidate pairs, with 292 unbatched versus 8 batched calls. Builds on #4209; motivated by [research #7](https://github.com/lancedb/research/pull/7). --- docs/src/python/python.md | 23 ++ python/benchmarks/bench_typesafe.py | 245 +++++++++++++ python/benchmarks/test_bench_typesafe.py | 109 ++++++ python/benchmarks/typesafe_batching.md | 99 +++++ python/benchmarks/typesafe_subset_test.json | 144 ++++++++ python/python/lancedb/rerankers/typesafe.py | 99 ++++- python/python/tests/test_rerankers.py | 39 +- python/python/tests/test_typesafe_reranker.py | 338 ++++++++++++++++++ 8 files changed, 1070 insertions(+), 26 deletions(-) create mode 100644 python/benchmarks/bench_typesafe.py create mode 100644 python/benchmarks/test_bench_typesafe.py create mode 100644 python/benchmarks/typesafe_batching.md create mode 100644 python/benchmarks/typesafe_subset_test.json create mode 100644 python/python/tests/test_typesafe_reranker.py diff --git a/docs/src/python/python.md b/docs/src/python/python.md index 68cd306c4..ccc44a55e 100644 --- a/docs/src/python/python.md +++ b/docs/src/python/python.md @@ -379,6 +379,29 @@ still work.

This includes real local vector/FTS/hybrid searches, async queries, +and TypeSafe SDK 0.7.1 over a mock HTTP transport (including SDK-managed retries). +Repository-wide Ruff formatting/lint, the benchmark CLI, and the MkDocs build +also passed. + +### Live subset test + +A live test on the first 100 cached GooAQ queries (6,851 candidate pairs) passed +with `jev-1.13.0`, SDK 0.7.1, and concurrency 32 in both modes. Candidate IDs, +probabilities, resolved models, and request counts were checked for every record. +All three 80-candidate queries made exactly two batched calls. Live vector, FTS, +hybrid, empty-FTS, and multivector integration checks also passed in both modes. +No correctness fixes were needed. + +The subsequent batch-ordering simplification passed all 124 automated tests and +a fresh four-query live check (original query indices 0, 1, 2, and 8; 292 candidate +pairs). Unbatched/batched calls were 292/8, including exactly two calls for the +80-candidate case. The 100-query measurements below are from the initial +implementation, identified by commit and source hash in the linked report. + +| Batch size | Subset SDK calls | Median | p95 | +| --- | ---: | ---: | ---: | +| 1 | 6,851 | 877 ms | 9,446 ms | +| 40 | 199 | 351 ms | 598 ms | + +| Search | Unbatched Hit@5 / Hit@10 | Batched Hit@5 / Hit@10 | +| --- | ---: | ---: | +| Vector | 82% / 88% | 84% / 89% | +| FTS | 72% / 77% | 73% / 78% | +| Hybrid | 83% / 89% | 84% / 90% | + +These are **subset-test observations, not full benchmark results**. The full run +was manually stopped after 494 matched queries; this summary uses the first 100 +input queries without selection by latency or scores. Counts above exclude other +queries completed before stopping. The high unbatched p95 is retained as observed; +it is not attributed to a specific cause. A complete 2,000-query paired benchmark +is still needed before making a general performance or quality claim. Exact values +and configuration are in [the subset test report](typesafe_subset_test.json). + +The historical GooAQ results motivated this patch: the earlier custom adapter +reported 186 ms median / 387 ms p95; native unbatched scoring at concurrency 32 +reported 805 ms / 1,193 ms for 2,000 queries and 136,586 candidate pairs using +`jev-1.13.0`. Those separate runs are not measurements of this patch. See the +[research results](https://github.com/lancedb/research/blob/codex/use-native-typesafe-reranker/reranking/results/README.md) +and [earlier adapter](https://github.com/lancedb/research/blob/412a522/reranking/jev_reranker.py). + +## Run the paired benchmark + +Use the exact `candidates.json` from the research benchmark cache. It is a JSON +array of records with `query`, expected `answer`, ordered `vector` and `fts` ID +lists, and a `documents` mapping from string IDs to text. Distinct IDs may have +identical text. To prepare candidates without scoring models, use the research +branch's [benchmark](https://github.com/lancedb/research/blob/codex/use-native-typesafe-reranker/reranking/compare_jev.py) +with `--models none`; its default corpus and query counts reproduce the protocol. + +After bootstrapping this checkout's Python development environment, run from +`python/` (set `TYPESAFE_API_KEY` or pass `--api-key-file`): + +```sh +uv run --extra tests --with typesafe-sdk==0.7.1 benchmarks/bench_typesafe.py \ + --candidates /path/to/research/reranking/.benchmark-cache/candidates.json \ + --model jev-1.13.0 --max-concurrency 32 \ + --cache /tmp/typesafe-batching-fresh \ + --output /tmp/typesafe-batching-results.json +``` + +Both modes use the same installed SDK, model, prompt, candidates, and concurrency. +They score each query's candidate union once, alternating which mode runs first. +Timings include native reranking and SDK retries, exclude retrieval, and report +median/p95 milliseconds. Request counts mean logical SDK calls, excluding +SDK-internal retry attempts. The output includes resolved model IDs, package +versions, implementation and candidate hashes, and vector/FTS/hybrid Hit@5 and +Hit@10. As in the research protocol, each metric uses 4× overfetch and a hit means +an exact match to the expected answer text. Ties retain retrieval order. + +Scores and timings can resume from a cache. Cache identities separate batch size, +request format, model, SDK version, concurrency, prompt, implementation, and input +candidate bytes. Use a new cache directory for fresh timings. The report identifies +reused queries; don't compare runs with different resolved models or environments. +API errors and malformed responses abort the benchmark without fallback scores. + +Offline validation from `python/`: + +```sh +uv run --extra tests --with typesafe-sdk==0.7.1 pytest \ + python/tests/test_typesafe_reranker.py \ + python/tests/test_rerankers.py benchmarks/test_bench_typesafe.py -k typesafe -q +``` diff --git a/python/benchmarks/typesafe_subset_test.json b/python/benchmarks/typesafe_subset_test.json new file mode 100644 index 000000000..31966e282 --- /dev/null +++ b/python/benchmarks/typesafe_subset_test.json @@ -0,0 +1,144 @@ +{ + "scope": "Live subset test: first 100 GooAQ queries, not a completed full benchmark.", + "full_benchmark_completed": false, + "source_commit": "ffae20f2acde4720d1ab8d724a66af6afa4a33cc", + "queries": 100, + "candidate_pairs": 6851, + "subset_selection": "First 100 input queries; no selection by scores or latency.", + "request_count_definition": "SDK calls for this subset only; excludes SDK-internal retries and other queries executed before the full run was stopped.", + "live_integrations": [ + "vector", + "FTS", + "hybrid", + "empty FTS", + "multivector" + ], + "results": { + "40": { + "identity": { + "candidates_sha256": "c5744f7a630f5626532f068e92df9a1e6eb34735b379e07df1a3c80d15cbb551", + "model": "jev-1.13.0", + "max_concurrency": 32, + "batch_size": 40, + "request_format": "query-state-structured-document-question-v1", + "instructions": "Does the candidate passage answer the user's query?

From: Xuanwo Date: Thu, 24 Sep 2026 18:02:25 +0800 Subject: [PATCH 69/74] fix(python): warn instead of failing on local imports in @udf source (#4318) Since 0.40.0b8 (#4254), `@udf` raises when the packaged source imports a module from a local source tree that is neither shipped with `code=` nor named by a declared pip/conda package. That turned registrations that used to succeed into errors: - Callers that rewrite the packaged source before registering it now fail at decoration. Sophon's datagen integration suite inlines its test-module helpers this way, and `test_registered_udf_source_stands_alone_on_a_worker` fails on 0.40.0b8. - The check cannot know which modules a distribution installs. A declared package whose distribution name differs from its module (for example an internal library installed editable) is reported as local, and there was no way to proceed. This keeps the diagnosis but makes it a `UserWarning`, so registration behaves as it did before #4254 and still tells the author, at registration time, why the worker is likely to fail. --- python/python/lancedb/functions.py | 25 +++++++++++++------ .../python/tests/test_function_packaging.py | 18 ++++++++----- 2 files changed, 29 insertions(+), 14 deletions(-) diff --git a/python/python/lancedb/functions.py b/python/python/lancedb/functions.py index 380625f57..5f26b590e 100644 --- a/python/python/lancedb/functions.py +++ b/python/python/lancedb/functions.py @@ -26,6 +26,7 @@ import re import sys import textwrap import types +import warnings from collections.abc import Mapping, Sequence from datetime import date, datetime from typing import ( @@ -1527,9 +1528,14 @@ class _SourcePackager: return f"{name} = {_literal_source(value)}" def _require_importable(self, module_name: str) -> None: - """Refuse an import the Function's environment has no way to satisfy: - a module that lives in a local source tree, is not shipped with - ``code=``, and names no declared package.""" + """Warn about an import the Function's environment likely cannot + satisfy: a module that lives in a local source tree, is not shipped + with ``code=``, and names no declared package. + + A warning rather than an error: a distribution name need not match + the module it installs, so a declared package can still provide the + module, and callers may rewrite the packaged source before + registering it.""" top = module_name.partition(".")[0] if ( top in self._code_modules @@ -1543,10 +1549,12 @@ class _SourcePackager: roots = _installed_roots() if not locations or any(location.startswith(roots) for location in locations): return - raise ValueError( + warnings.warn( f"@udf source imports {module_name!r} from {locations[0]}, a local " - "module the Function's environment cannot import; ship it with " - f"code=[{top}] or declare the package that provides it in pip/conda" + "module the Function's environment may not be able to import; ship " + f"it with code=[{top}] or declare the package that provides it in " + "pip/conda", + UserWarning, ) @@ -1991,8 +1999,9 @@ def udf( place.

This adds `pause_job` and `resume_job` to the Rust core connection and the Python bindings (sync and async), posting to the server's `/v1/jobs/pause` and `/v1/jobs/resume` endpoints. A pause parks the job until it is resumed: its workers drain and stop. The outcome strings mirror the server's answers — a job finalizing its results reports `"committing"` and cannot be parked, and a resume before the drain is confirmed reports `"still_pausing"`; both are retried rather than failed. Resuming re-queues the job and its workers pick their work back up from checkpoints. Local connections report the operations as unsupported, like the rest of the jobs API. --- docs/src/js/classes/Connection.md | 44 ++++++++++++++++ nodejs/__test__/remote.test.ts | 21 ++++++++ nodejs/lancedb/connection.ts | 26 ++++++++++ nodejs/src/connection.rs | 28 ++++++++++ python/python/lancedb/_lancedb.pyi | 2 + python/python/lancedb/db.py | 53 +++++++++++++++++++ python/python/lancedb/remote/db.py | 16 ++++++ python/python/tests/test_remote_db.py | 23 ++++++++ python/src/connection.rs | 24 +++++++++ rust/lancedb/src/connection.rs | 16 +++++- rust/lancedb/src/database.rs | 33 ++++++++++++ rust/lancedb/src/remote/db.rs | 75 ++++++++++++++++++++++++++- rust/lancedb/src/remote/job.rs | 22 ++++++++ 13 files changed, 380 insertions(+), 3 deletions(-) diff --git a/docs/src/js/classes/Connection.md b/docs/src/js/classes/Connection.md index a51fb986a..f1aace87b 100644 --- a/docs/src/js/classes/Connection.md +++ b/docs/src/js/classes/Connection.md @@ -823,6 +823,28 @@ abstract openTable( *** +### pauseJob() + +```ts +abstract pauseJob(jobId): Promise +``` + +Pause a server-side job by id. + +The job's workers drain and it stays parked until resumed.

Basically, the existing code just calls a vector query + FTS query and dedups locally using the row ID. Since row ID is unsupported in WAL (currently), we update the algorithm to use the tables PK (which is required in WAL, and uniquely linked to a PK on updates). To enable PK-dedup branch, we've chosen to fallback on error rather than fire an exploratory query. Specifically, we issue the regular hybrid query, using row IDs, and when that fails with "WAL does not support row IDs" we fallback to the PK-based variant, and then cache the fallback for future calls from the same client. The alternative is that we chec if WAL is enabled before issuing the query. This would require a `get_lsm_write_spec` call, slowing down all the existing non-WAL paths unnecessarily. The ultimate goal is to get row ID supported in WAL, but that is pending stable row ID GA and subsequent integration into the enterprise stack. Once that lands, we will rip out the PK-based dedup that is only for WAL-enabled tables and use the existing row ID code. This is the main reason for building this adaptively. I had spec-ed out a refactor so that rather than duplicating code between python and rust we build this in rust and have python call that through PyO3. However, that made the reverse path (ie. ) more difficult. So I think the tradeoff of maintaining duplicate code in the short term for the ease of reverting this in the medium term (hopefully 2-3 months). --------- Co-authored-by: Claude Opus 5 --- python/python/lancedb/_lancedb.pyi | 3 + python/python/lancedb/_wal_hybrid.py | 282 +++++++++++++ python/python/lancedb/query.py | 130 +++++- python/python/lancedb/remote/table.py | 8 + python/python/lancedb/table.py | 21 + python/python/tests/test_wal_hybrid.py | 219 +++++++++++ python/src/table.rs | 15 + rust/lancedb/src/query.rs | 44 ++- rust/lancedb/src/query/wal_fusion.rs | 523 +++++++++++++++++++++++++ rust/lancedb/src/remote/table.rs | 292 ++++++++++++++ rust/lancedb/src/table.rs | 25 ++ 11 files changed, 1538 insertions(+), 24 deletions(-) create mode 100644 python/python/lancedb/_wal_hybrid.py create mode 100644 python/python/tests/test_wal_hybrid.py create mode 100644 rust/lancedb/src/query/wal_fusion.rs diff --git a/python/python/lancedb/_lancedb.pyi b/python/python/lancedb/_lancedb.pyi index 337b736ce..1f26ad6f4 100644 --- a/python/python/lancedb/_lancedb.pyi +++ b/python/python/lancedb/_lancedb.pyi @@ -514,6 +514,9 @@ class Table: async def set_lsm_write_spec(self, spec: LsmWriteSpec) -> None: ... async def unset_lsm_write_spec(self) -> None: ... async def get_lsm_write_spec(self) -> Optional[LsmWriteSpec]: ... + # WAL-PK-FUSION: delete both. + def hybrid_pk_fusion_learned(self) -> bool: ... + def note_hybrid_pk_fusion(self) -> None: ... async def checkpoint_lsm(self) -> None: ... async def flush_lsm(self) -> None: ... async def compact_lsm(self) -> None: ... diff --git a/python/python/lancedb/_wal_hybrid.py b/python/python/lancedb/_wal_hybrid.py new file mode 100644 index 000000000..67597950d --- /dev/null +++ b/python/python/lancedb/_wal_hybrid.py @@ -0,0 +1,282 @@ +# SPDX-License-Identifier: Apache-2.0 +# SPDX-FileCopyrightText: Copyright The LanceDB Authors + +"""WAL-PK-FUSION: hybrid search's primary-key fallback for MemWAL tables. + +Hybrid search joins its vector and full-text legs on `_rowid`, which a MemWAL +table cannot supply: the fresh tier has no stable row id, so the server rejects +`with_row_id` before it plans.
