feat: define a materialized view by its query, with Functions in FROM position (#4190)
A view definition was a structured record under a `kind` tag, one kind per query shape, and a Function returning `list<struct>` was about to add a third. 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. A local database refuses a Function in FROM position, since it has no executor. |

feat: list a table's per-row Function errors from the client (#4208)
A refresh running under a skip policy records each row it skipped, with the failing input and the error, but the client could not read that store: the server exposes it over SQL and, since recently, a REST route. 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. |

feat(secrets): named Secrets, bindings, and namespace addressing (#4150)
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).

feat: add remote catalogs and Python and TypeScript bindings (#4195)
Add a `Catalog` trait and `RemoteCatalog` for managing databases,
exposed through Rust, synchronous/asynchronous Python, and TypeScript. 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<dyn Database>`; 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<String>; page.page_token: Option<String>
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.

feat: use oauth2 crate for OAuth with configurable client auth (#4181)
Stacked on #4173 (`jack/restore-oidc-flows`, base branch mirrored to this repo so the diff shows only this change); context from review: https://github.com/lancedb/lancedb/pull/4173#issuecomment-5674048100. 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. Co-authored-by: Xuanwo <github@xuanwo.io> |

fix(node): prevent OAuth tests from launching browsers (#4196)
OAuth tests set `LANCEDB_OAUTH_BROWSER` inside Jest's sandbox, which does not update the process environment read by Rust. 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. |

feat(nodejs): add JSON field helper (#4082)
## 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. |

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`.

feat: add persistent OAuth token cache and session APIs (#4182)
Stacked on #4173 (diff includes it until that merges; will rebase after). 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 <github@xuanwo.io> |

chore: update lance dependency to v13.0.0-beta.1 (#4183)
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 <bubble-cal@outlook.com> Co-authored-by: Claude Fable 5.1 <noreply@anthropic.com> |

fix(node): preserve optimize cleanup timestamp (#4160)
<!-- lance-gatekeeper-fix:v1 agent=278cb095b2e5d69051442bc254d803a6 generation=1 --> ## Summary - pass the TypeScript `cleanupOlderThan` date to the native binding as an unchanged epoch timestamp - prune with Lance's absolute `before_timestamp` policy so dispatch and compaction time cannot move the cutoff - retain versions created after the supplied cutoff and document that behavior - add boundary and end-to-end regression coverage ## Root cause The TypeScript layer converted the absolute date into an elapsed duration before calling native optimize. Lance converted that duration back into a timestamp only after compaction, which silently advanced the requested cutoff and made the cleanup count depend on a millisecond timing boundary. ## Validation - `cargo fmt --all` - `cargo clippy --quiet --features remote --tests --examples -p lancedb -p lancedb-nodejs` - `pnpm build` - `pnpm lint` - `pnpm run docs` - `pnpm test __test__/table.test.ts --runInBand` (309 passed) Fixes #4159 --------- Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com> Co-authored-by: Xuanwo <github@xuanwo.io> |

feat(node): add blob v2 fetch and field helpers (#4155)
this PR blob v2 field helpers and reads to the Node SDK.
`blob()` marks a field as blob v2 and lets you set the storage
thresholds. Inputs can be bytes, a URI, or a data/uri struct.
Queries return descriptors. `fetchBlobs()` reads the bytes by row ID,
and `fetchBlobFiles()` gives you lazy handles for full or range reads.
`blobColumns()` lists the blob fields, including nested ones.
Fetch uses the table’s current checkout. It preserves order, duplicates,
and nulls. Holding row IDs across compaction still requires stable row
IDs.
```javascript
const db = await connect("./data");
const video = await readFile("clip.mp4");
const table = await db.createTable(
"videos",
[{ id: 1n, video }],
{
schema: new Schema([
new Field("id", new Int64()),
blob("video"),
]),
},
);
const rows = await table.query().select(["id"]).withRowId().toArray();
const rowIds = rows.map((row) => row._rowid as bigint);
const bytes = await table.fetchBlobs("video", rowIds);
const [handle] = await table.fetchBlobFiles("video", rowIds);
const header = await handle!.readRange(0n, 65536n);
```
### Testing
- cover input validation, thresholds, nested fields, fetch ordering,
nulls, and range reads.

ci: add spell checking (#4148)
Adds [typos](https://github.com/crate-ci/typos) as a CI check and pre-commit hook, the same way Lance does it, so misspellings like the ones fixed in #4146 get caught automatically going forward. This also fixes the misspellings `typos` found across the repo (Rust, Python, TypeScript source, comments, and generated docs), and adds a small `.typos.toml` with `extend-words` entries for terms that are correct but look like typos: `AKS` (Azure Kubernetes Service), `RabitQ` (a real quantization algorithm name), `mmaped` (the actual name of a `candle-core` API we call), and `Writeable` (from Python's `_typeshed.WriteableBuffer`). Third-party license files are excluded. Fixes #4147 Co-authored-by: Claude Sonnet 5 <noreply@anthropic.com> |

feat!: replace get_job/job_history with describe_job/query_job_events (#4130)
A 1M-row column refresh over 200 fragments produced no visible result,
and the client could only ever say `"running"`. Everything needed to
diagnose it already existed server-side — the job registry records a
`claim`/`claim_complete` pair per fragment carrying `rows_processed` —
but none of it was reachable.
## Before
Four ways to ask about a job, none of which told you much.
```python
job = table.refresh_column_async("embedding")
job.status() # "running". That was the entire debug surface.
db.get_job(job_id) # state, and a spec. No result, no progress.
db.job_history(job_id) # raw record batches, no limit, no filter
db.job(job_id) # a handle that knew nothing
```
## After
Open a job the way you open a table; the handle answers everything.
```python
job = db.open_job(job_id) # raises JobNotFoundError if there is no such job
```
```python
>>> print(job)
Job(
id='job-1',
state='failed',
job_type='refresh_column',
creation_ms=1757000000000,
spec={
"column": "embedding",
"num_workers": 4
},
failure=JobFailureInfo(phase='execute', message='worker died', retryable=True),
)
```
Individual fields are there too — `job.state`, `job.job_type`,
`job.creation_ms`, `job.spec`, `job.result`, `job.failure` — and
`job.result` carries `rows_assigned` / `rows_failed` as soon as the job
succeeds, with no `wait()` required.
Per-fragment progress *while it is still running*:
```python
done = job.events(filter="state = 'claim_complete'", limit=10_000)
done.column("rows_processed").to_pylist() # [5000, 5000, ...]
```
The handle an async action returns is the same object, one `refresh()`
away:
```python
job = table.refresh_column_async("embedding")
job.refresh()
job.state, job.result
```
TypeScript is the same experience, down to `console.log`:
```ts
const job = await db.openJob(jobId); // rejects if there is no such job
console.log(job); // same multi-line layout
job.state; job.jobType; job.spec; job.result; job.failure;
const done = await job.events({ filter: "state = 'claim_complete'", limit: 10_000 });
```
## Why each piece matters
- **A result without waiting.** `rows_assigned` / `rows_failed` used to
live only on the terminal result, so a job that never terminated
reported nothing at all.
- **`limit`.** The server caps event rows at 1000 and truncates without
saying so, which silently hid most of a 200-fragment job's history.
- **`filter`.** `claim_complete` rows carry per-claim `rows_processed` —
the only progress signal that exists mid-flight.
- **Events outlive the worker.** They live in the job registry, not in
pod logs that vanish with the pod.
- **One place to ask.** `open_job` replaces `describe_job`,
`query_job_events` and `job`, so a question about a job has one answer
instead of one per calling location.
- **A missing job is an error, not a `None`.** The common case is a job
id copied out of a log, where absence is the surprise worth raising —
and it matches `open_table`.
- **Printing is the debug surface.** Every field on its own line, JSON
payloads keeping their structure. An unrefreshed handle stays on one
line, because there is nothing to lay out.
- **In-process jobs say so.** A local refresh reports `state` and leaves
the rest null rather than inventing fields it has no record for.
`list_jobs` and `cancel_job` stay as they were: one lists, the other is
a one-shot action that should not need a describe first.
## Breaking
All shipped in 0.38.0. No deprecated aliases.
| Was | Now |
| --- | --- |
| `Connection.get_job` → `describe_job` | `Connection.open_job` returns
a populated `Job`, or raises |
| `Connection.job_history` → `query_job_events` | `job.events(...)` |
| `Connection.job` | `Connection.open_job` |
| Python events → `List[pa.RecordBatch]` | `pa.Table` |
| `JobDescription.spec_json` / `.result_json` | internal; use `job.spec`
/ `job.result` |
Node's `Job` is now a TypeScript class wrapping the native handle, so it
returns an Arrow table and parsed values like Python does. New
`Error::JobNotFound` / `JobNotFoundError`; the three job exceptions are
now in the Python API reference.

feat: accept multiple on columns for merge insert on remote tables (#4102)
Merge insert has always taken a list of columns to match on, and local tables have always joined on all of them. Remote tables did not: any list longer than one was rejected with `MergeInsertBuilder only supports a single 'on' column`, so a composite-key upsert was impossible against LanceDB Cloud and Enterprise from Rust, Python or TypeScript. The remote request now carries `on` as a list and sends it as one repeated query parameter per column — `?on=shard_key&on=id`. That is how the lance-namespace spec encodes an array-valued `on`, so the server receives a composite key in the shape it expects. A single column still serializes to `?on=id`, exactly what clients sent before, so existing callers are unaffected. A column repeated within `on` is now rejected client-side rather than sent for the server to reject with a 400. No binding changes were needed: `Table.merge_insert` in Python and `Table.mergeInsert` in TypeScript already accepted a list, it just could not reach a remote table. Both gain a test for composite keys, and the doc comments now say what passing several columns means. Part of [ENT-2084](https://linear.app/lancedb/issue/ENT-2084/mergeinsertintotablerequest-support-multiple-columns-for-the). ## Example ```python table.merge_insert(["shard_key", "id"]) \ .when_matched_update_all() \ .when_not_matched_insert_all() \ .execute(new_data) ``` A row whose `id` matches an existing row but whose `shard_key` differs is an insert, not an update. ## Not included Java. Java callers reach merge insert through `org.lance.namespace.LanceNamespace`, whose `MergeInsertIntoTableRequest.on` is a single string until lance-namespace 0.12 ([lance-namespace#363](https://github.com/lance-format/lance-namespace/pull/363), [lance#8915](https://github.com/lance-format/lance/pull/8915)). There is nothing in this repo's Java SDK to change until the `lance-core` pin can move. Sending more than one column requires a server that accepts the repeated parameter ([sophon#7571](https://github.com/lancedb/sophon/pull/7571)); an older server returns a 400 rather than silently merging on one column.

feat: record the source namespace in a materialized view definition (#4098)
A view definition recorded its source by bare name and refresh resolved that name at the root, so declaring a view over a namespaced source was refused outright -- materialized views were root-only for every caller. The definition now carries `source_namespace`, and refresh opens the source at that coordinate. `plan` takes the namespace too: refresh re-plans the stored definition and persists the result when it migrates, so defaulting it there would strand the view on its next rebuild. The stored kind is the version boundary. Root definitions keep the `select` form byte-for-byte, so everything written before this change reads exactly as it always did. A namespaced source is stored as `namespaced_select`: released readers drop unknown fields and resolve a `select` source at the root, so keeping the old kind would let a rolled-back worker refresh a view from a same-name root table -- the new kind routes them to their existing unrecognized-kind refusal instead. The Python and Node definition parsers learn the new kind alongside the Rust core. |

feat(node)!: require Node >= 22 and drop npm lockfiles (#4074)
The bindings are built, installed and published with pnpm everywhere,
but a parallel npm dependency graph was still being maintained beside
it. This removes it, raises the supported Node floor to the versions we
actually test, and gives Dependabot the npm coverage it was missing.
## Dropping npm
`nodejs/package-lock.json` was regenerated by `ci/update_lockfiles.sh`
on every release commit and read by nothing — no workflow runs `npm ci`
or `npm install` in `nodejs/`, and npm never publishes a lockfile in a
package tarball. It could not even agree with the real install, since
npm does not see pnpm's `overrides`. Because GitHub's dependency graph
parses `package-lock.json`, it was also reporting vulnerabilities for a
tree we neither install nor ship.
`docs/package.json`, `docs/package-lock.json` and `docs/tsconfig.json`
go too. They depend on `file:../node` and
`file:../node/node_modules/apache-arrow` — the `node/` directory was
removed long ago — the tsconfig compiles `src/*.ts` where no TypeScript
files exist, and nothing installs any of it. `docs.yml` only referenced
the lockfile to configure an npm cache for an install it never ran.
Two `workflow_dispatch` workflows for regenerating those lockfiles are
removed as well. Both were already broken: they `uses:` composite
actions at `.github/workflows/update_package_lock{,_nodejs}` that do not
exist, so dispatching either failed immediately.
The remaining `npx` calls become direct `node_modules/.bin/...`
invocations. These were already running locally installed binaries
rather than resolving anything, but naming the binary removes the npm
CLI from the loop and does not depend on which Node version is active.
`dev.yml`'s commitlint check was the last place doing real npm
dependency resolution — an unpinned `npm install
@commitlint/config-conventional` that also bypassed the
`minimumReleaseAge` hold configured for `nodejs/` — and is now a pinned
`pnpm dlx`.
## Node support
Node 18 and 20 both reached end-of-life, in April 2025 and April 2026.
The matrix moves to 22, 24 and 26, and `engines` rises from `>= 18` to
`>= 22` so the declared floor is one the matrix actually covers. Node 22
is LTS until April 2027; 24 is LTS; 26 is Current and becomes LTS in
October 2026.
This also removes the reason the workflows reached for `npx` in the
first place: pnpm 11 requires Node >= 22.13, which every matrix version
now satisfies.
The prebuilt-binary smoke test in `npm-publish.yml` moves from Node 20
to Node 22 — the floor, where a napi ABI problem would surface first —
rather than fanning out across all three, to keep the publish matrix
from tripling.
## Dependabot
There were no npm-ecosystem entries at all, which is why the advisories
behind #4073 went unnoticed. Both pnpm lockfiles are now watched —
`nodejs/` and `nodejs/examples/`, which is a separate install — using
the same `lockfile-only` strategy as the existing cargo and pip entries,
so version ranges in `package.json` are left alone.
## Pre-commit biome
The hook ran `npx @biomejs/biome@1.8.3` while `nodejs/package.json`
resolved 1.9.4. The two disagree about formatting, so the hook rejected
code that `pnpm lint` accepts, and failed on unmodified `main` for
anyone touching `nodejs/`. It now uses the pnpm-managed biome, which
fixes the drift with no source changes.
## Testing
`dev.yml`'s commitlint job does not check out the repo, so it runs in an
empty workspace, and I could not verify `pnpm/action-setup` there
locally. It triggers on `pull_request_target`, so this PR exercises it
directly — worth confirming green before merge. I did verify the `pnpm
dlx` invocation itself locally: it accepts a conventional title and
rejects a non-conventional one with exit 1.
Node 26 is new enough that the examples job may surface gaps in prebuilt
native binaries (`onnxruntime-node`, `sharp`) before their maintainers
publish for it.
## Not included
`nodejs/examples/` still pins `sharp: "0.33.5"` and has its own audit
findings. Raising the Node floor unblocks that work — sharp 0.35
requires Node >= 20.9, which the matrix now satisfies — but it is a
dependency bump rather than tooling cleanup, so it is left separate.
## Breaking changes
`@lancedb/lancedb` now requires Node >= 22; previously >= 18. The
`@types/node` peer range moves from `>=18` to `>=22` to match. Users on
Node 18 or 20 must upgrade their runtime; both have been end-of-life for
some time. Existing installs are unaffected, since `engines` is only
checked on install.

fix(node): accept Arrow metadata across JavaScript realms (#3904)
## Summary - accept genuine Arrow metadata maps created in another JavaScript realm - validate every metadata entry and clone it into a local Map - cover an Arrow 15 VM-realm table through the public fromDataToBuffer boundary - retain structural typing for nested and dictionary Arrow data ## Root cause The sanitizer used a local-realm instanceof Map check for schema and field metadata. A genuine Map created in another JavaScript realm has the required internal Map state but fails that identity check, so fromDataToBuffer rejected the foreign table before serializing its rows. ## Scope This fixes the distinct JavaScript-realm sanitizer failure identified during review. It does not establish the cause of the S3/compaction panic reported in #1525, so that issue remains open. ## Validation - pnpm test --runInBand (707 passed, 5 skipped) - pnpm test --runInBand __test__/arrow.test.ts (189 passed) - pnpm build - pnpm lint - pnpm run docs Related to #1525 <!-- lance-gatekeeper-fix:v1 agent=b522628ad3bae914eb7266ccd899d508 generation=1 --> --------- Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com> Co-authored-by: Xuanwo <github@xuanwo.io> |

The missing source name reached the add path as `undefined`, preventing JavaScript rows from being embedded and appended. ## Validation - `pnpm lint` - `pnpm test __test__/embedding.test.ts __test__/arrow.test.ts __test__/registry.test.ts --runInBand` (201 passed, 1 skipped) - `pnpm build` - `pnpm run docs` Fixes #1289 <!-- lance-gatekeeper-fix:v1 agent=b71c18a5e33d26f4d138972e91d34e66 generation=1 --> --------- Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com> Co-authored-by: Xuanwo <github@xuanwo.io> |

fix(node): route auto search using table embeddings (#3832)
## Summary - Resolve automatic string-search routing from the active table schema whenever the query executes. - Defer embedding-provider construction while leaving explicit vector and FTS routes unchanged. - Cover unrelated global registrations and metadata transitions across repeated executions of one query builder. ## Root cause LocalTable.search used the number of globally registered embedding providers to choose between vector and full-text search. A provider registered for any other table therefore sent a plain FTS table down the vector path. A wrapper-lifetime metadata snapshot avoided that contamination but became stale after time travel or read-consistency refreshes. The query now records fluent builder operations and creates the appropriate native vector or FTS query from the active schema on each execution. ## Validation - pnpm build - pnpm tsc - pnpm lint - pnpm run docs - pnpm test --runInBand (681 passed, 5 skipped) Fixes #1557 <!-- lance-gatekeeper-fix:v1 agent=b6183df8296db4aabdc5d19a2256b029 generation=1 --> --------- Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com> Co-authored-by: Xuanwo <github@xuanwo.io> |

test(node): cover nested PDF metadata queries (#3827)
## Summary - add an end-to-end Node regression matching LangChain PDFLoader metadata - verify create/query round trips rich nested `loc` and `pdf.info` fields against the currently configured Apache Arrow peer ## Root cause LanceDB v0.14 delegated nested object inference to Apache Arrow. Nested strings were dictionary-encoded with colliding dictionary IDs, so serializing query results as an IPC file failed with a dictionary-replacement error. Current `main` recursively infers nested fields and avoids those invalid dictionaries, but the reported LangChain path had no end-to-end regression coverage. ## Validation - `pnpm build` - `pnpm lint` - `pnpm run docs` - `pnpm test --runInBand` (678 passed, 5 skipped) Fixes #1963 <!-- lance-gatekeeper-fix:v1 agent=bf8d489db7db2e17678b143f9f0a36d2 generation=1 --> --------- Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com> Co-authored-by: Xuanwo <github@xuanwo.io> |

fix(node): preserve embedding registration in server bundles (#3806)
## Summary
- lazily initialize built-in OpenAI and Hugging Face providers when
consumers call the public embedding registry API
- choose automatic vector versus FTS search from embedding metadata on a
fresh pinned table revision for every execution
- expose automatic string searches as an `AutoQuery` with only
operations common to both native query families
- keep the registry shared and built-in registration safe across
duplicated module graphs
## Root cause
Nitro treats dependency modules as side-effect-free and removes the bare
OpenAI provider import from its generated route. Registration therefore
never runs, so `getRegistry().get("openai")` remains undefined even when
the registry itself is shared globally. Bundlers may also duplicate the
provider and registry module graphs.
The public embedding entry point now initializes built-in providers only
when `getRegistry()` is explicitly called, keeping initialization on a
live path that Nitro retains. Each terminal automatic-search execution
pins the exact table revision visible at dispatch, reads embedding
metadata and computes an embedding from that snapshot, replays the
builder operations, and constructs and executes the selected native
query against the same snapshot. Pinned native snapshots execute locally
when namespace pushdown cannot carry their revision, while remote
snapshots are seeded directly from one version-and-schema response. The
public `AutoQuery` builder exposes only the operations shared by FTS and
vector search, so runtime class narrowing cannot expose invalid
vector-only methods. Repeated built-in registration replaces stale
constructors from duplicated module graphs while public `register()`
retains its duplicate-alias error.
## Validation
- `cargo fmt --all`
- `cargo check --quiet --features remote --tests --examples`
- `cargo clippy --quiet --features remote --tests --examples`
- `pnpm build`
- `pnpm lint`
- `pnpm run docs`
- `pnpm test --runInBand` (783 passed, 5 skipped)
- serial examples suite with a local OpenAI mock (11 passed), including
`sentence-transformers.test.ts`
- packaged Nitro 2.13.4 server route using the reported imports returned
`{"registered":true}`
- fresh-process FTS fixture initialized both public built-ins and
confirmed automatic string search still returned the indexed row
- schema-consistency regressions cover read-consistency refresh,
checkout, checkoutLatest, restore, runtime class narrowing, concurrent
overwrite during embedding computation, and reused automatic-search
builders
- focused regressions confirm pinned native snapshots bypass unversioned
namespace pushdown and remote snapshots use one describe request
Fixes #2429

feat(nodejs): add listTables, deprecate tableNames (#4041)
`table_names` is being replaced by `list_tables` across the SDKs, but TypeScript only had `tableNames`. This PR adds `listTables`, which returns a page of table names together with the token that resumes after it, and marks `tableNames` and `TableNamesOptions` deprecated in favor of it. It binds the `Connection::list_tables` that already exists, so nothing in the Rust API changes and nothing existing breaks. `pageToken` is documented as opaque rather than as a table name, since what resumes a listing is the database's to decide — that keeps callers off a detail that is going to change. Stacked on #4040, which fixes a table being dropped at every page boundary. The page-walking test here needs that fix to pass. Review the last commit only until #4040 lands. ## Example ```ts const names = []; let pageToken = undefined; do { const page = await conn.listTables({ pageToken, limit: 100 }); names.push(...page.tables); pageToken = page.pageToken; } while (pageToken); ``` A namespace can be listed by passing its path first, mirroring `tableNames`: ```ts const page = await conn.listTables(["analytics"], { limit: 100 }); ``` Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com> |

feat(nodejs): materialized view bindings (#3935)
Exposes materialized views to TypeScript: createMaterializedView,
openMaterializedView and listMaterializedViews on Connection, and a
MaterializedView handle carrying the parsed definition and
refresh({full, sourceVersion}), which returns the typed refresh result.
select accepts column names, [alias, expression] pairs, or a record of
the
same; the definition reads back off the stored schema, so a reopened
handle
needs no side channel. Remote connections surface the core's
not-supported
error up front.
The napi crate needed the same recursion-limit raise as the core crate:
the
refresh future's type graph overflows the default trait-recursion depth.

feat!: rename branch merge to cherry_pick (#3986)
This PR is a **breaking** rename of #3686. merge reads like git merge w/ three-way, replay history, combine two lines of work. That is not this API. This call takes one additive change on a branch and lands it on main. New column, including a blob column. Main's existing columns are not rewritten. If it cannot land, you get `status="failed"` and `diff.errors`, not a merge conflict to resolve. Cherry-pick is terminology that aligns more with that. ```python table = db.open_table("images") table.branches.create("exp") exp = table.branches.checkout("exp") exp.add_columns({"tag": "cast('draft' as string)"}) diff = table.branches.diff("exp") preview = table.branches.cherry_pick("exp", dry_run=True) result = table.branches.cherry_pick("exp") if result["status"] == "cherryPicked": print("landed at", result["mainVersionAfter"]) elif result["status"] == "failed": print(result["diff"]["errors"]) ``` ### Behavior - Remote / Enterprise only. Local still NotSupported. - HTTP 409 is not an exception. It is Ok with status="failed" and diff.errors (CherryPickError). - Unknown error / status codes still parse as Unknown. - Requests are not retried. 409 is final and carries the body. - Endpoint is POST /v1/table/{id}/branches/cherry_pick/. - merge_insert and Table.merge are unchanged. ### Testing - `cargo test -p lancedb --features remote diff_branch` - `cargo test -p lancedb --features remote cherry_pick` - `pytest python/python/tests/test_remote_db.py -k cherry_pick` - node `remote.test.ts` diffs / cherry-picks path |

fix(nodejs)!: key parsed embedding configs by vector column (#4003)
Two bugs in Node's reading of the embedding_functions schema metadata. First, parseFunctions keyed its result map by function name, so a table whose metadata configures the same function for two vector columns came back with only the last one. It now keys by the vector column, the convention Python's parser already uses. Second, Node could not read metadata written by the Python bindings at all, which spell the keys snake_case: configs parsed with both columns undefined, breaking embedding application on add() and leaving only query-side embedding working. The parse now accepts both spellings. Both fixes land in one shared parser used by every reader -- parseFunctions and the makeArrowTable schema validator, which had its own private camelCase-only parse -- so the wire contract cannot fork between entry points. A config naming no source or vector column is an error at the boundary rather than a default downstream, as are two configs claiming one column. The "vector" fallback remains only on the optional field of user-supplied configs. Breaking: parseFunctions is exported and its map keys change from function name to vector column.

feat: bring the MemWAL LSM surface to parity across the SDKs (#3962)
## Why Four of the eight LSM methods are **remote-only in the core**. `impl BaseTable for NativeTable` implements only `set`/`unset`/`get_lsm_write_spec` and `close_lsm_writers`; `flush_lsm`, `compact_lsm` and `get_lsm_stats` fall through to trait defaults returning `NotSupported` (`rust/lancedb/src/table.rs:679,687,696`), and `checkpoint_lsm` is built on all three. That explains the state of the bindings: Node had bound the four that work against a local table and stopped, so a Cloud user could install an LSM write spec but had no way to observe fresh-tier state or drive a checkpoint. Java had none of it at all. | SDK | set/unset/get spec | closeWriters | flush | compact | getStats | checkpoint | |---|---|---|---|---|---|---| | Rust core | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ | | Python | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ | | Node *(before)* | ✅ | ✅ | — | — | — | — | | **Node (after)** | ✅ | ✅ | **new** | **new** | **new** | **new** | | Java *(before)* | — | — | — | — | — | — | | **Java (after)** | **new** | n/a | **new** | **new** | **new** | **new** | Go and C are separate repos and are out of scope here. `closeLsmWriters` drains cached in-process shard writers, so it has no meaning for Java, which is a pure REST client. ## Node Adds napi bindings for `flushLsm`, `compactLsm`, `checkpointLsm` and `getLsmStats`, plus typed `LsmStats` / `BucketStats` / `GenerationStats` / `MemtableStats` objects — typed rather than a JSON blob, matching the existing `LsmWriteSpec` object in the same file, with `u64` cast to `i64` per that file's convention. Because these four are remote-only, the new tests assert each binding reaches the core and surfaces `NotSupported` against a local table. That covers the wiring; behavior against a real endpoint stays covered by the mocked-endpoint tests in `rust/lancedb/src/remote/table.rs`. ## Python No new methods. All eight are on `LanceTable`, `AsyncTable` and `RemoteTable` — the last four landed on the sync `RemoteTable` in #3961, which is merged into this branch. What was missing here was reachability. `LsmWriteSpec` was importable only from the private `lancedb._lancedb`, appearing in `table.py` solely under `if TYPE_CHECKING:`, and `docs/src/python/python.md` had no mention of it, which per the repo's docs guidance means it rendered nowhere in the API reference. It is now `lancedb.LsmWriteSpec`, in `__all__`, and documented. ## Java Java reaches LanceDB purely over REST through the generated Lance Namespace client, and these routes are not in that spec, so they are issued through a small dedicated client rather than added to the spec. That call is revisitable — LSM is one of four unspecified route families alongside `multipart_write`, `page_cache/prewarm` and `branches/diff|merge`. If those are ever regularized into the spec as a group, `LanceDbTableLsm` is one file that gets deleted. `LsmWriteSpec` here is deliberately **not** `org.lance.memwal.InitializeMemWalParams`. That type defaults to maintaining *no* indexes where a spec here defaults to maintaining *every* index, and it cannot express the `null` that asks the server to resolve the set: | Value | On the wire | Meaning | |---|---|---| | unset (null) | `null` | Server resolves **every** maintainable index | | `Collections.emptyList()` | `[]` | Maintain **none** | | `Arrays.asList("id_idx")` | `["id_idx"]` | Exactly those | A dedicated test pins null and `[]` as distinct on the wire, since collapsing them is the failure mode that motivated a LanceDB-owned type. `checkpointLsm` is ported from `rust/lancedb/src/table/checkpoint.rs` with its constants and status semantics intact: 429/503 retried in place against an 8-budget, 421 restarting from flush against a 3-budget, 5s poll, and a target watermark fixed after the seal so it terminates under write load. `getLsmStats` returns typed `LsmStats` / `BucketStats` / `GenerationStats` / `MemtableStats`, mirroring the Rust structs in `rust/lancedb/src/table/lsm_stats.rs` and the objects Node exposes. Decoding is strict — see below. ## Review feedback Both gatekeeper findings were real. Each was reproduced against the scripted test server first, and each fix ships with the reproducer as a regression test. **The transport was doubling every checkpoint retry budget.** `HttpClients.createDefault()` installs Apache's default response retry strategy, whose retryable-status list is exactly 429 and 503 — the two statuses `isRetryable` owns. A 429 held against `flush_lsm` issued **18** wire requests where the loop intends 9, and `compact_lsm` was retried in place despite the loop being built to fall through to a fresh stats poll instead. Timing confirmed the mechanism: that run took 25.4s ≈ 16.3s of the loop's own backoff plus 9 × the transport's 1s retry interval. Automatic retries are now disabled, so the checkpoint loop is the sole owner of the 421/429/503 transitions. A side effect worth noting: `testCheckpointRetriesRetryableStatusInPlace` was passing on a transport-absorbed 429 and never reaching `issue()`'s retry branch at all. It now exercises the real path. **Stats decoding failed open.** `getLsmStats` read the response with Jackson's `path()`, which yields a missing node that iterates as an empty array — making "malformed" indistinguishable from "no buckets", which is indistinguishable from "drained". Four separate payloads made `checkpointLsm()` report convergence for a checkpoint that never ran: | Response | Before | Now | |---|---|---| | `{"lsm_stats": null}` or absent key | disabled ✓ | disabled ✓ | | `{"lsm_stats": {}}` | **reported success** | `IllegalStateException` | | empty response body | **reported success** | `IllegalStateException` | | bucket missing required fields | **reported success** | `IllegalStateException` | The empty-body row is the one to weight: a proxy 200 with no body is a realistic production event, and it silently reported a checkpoint that never happened. Decoding is now strict and fails closed, matching the serde contract on the Rust side exactly. One deliberate deviation from the review comment, which asked that *only* explicit JSON `null` count as disabled: Rust has `#[serde(default)]` on `lsm_stats`, so an **absent key** decodes to `None` there too. Java now matches that. It is an absent-or-malformed **`buckets`** that fails closed, which is the case the comment was actually protecting. ## Testing - Java: **33 passing** (8 existing + 25 LSM) against a scripted `com.sun.net.httpserver.HttpServer` — no new test dependency. Wire assertions mirror `rust/lancedb/src/remote/table.rs:6581-6748`; checkpoint tests cover convergence, not piling onto a latched bucket, 421 restart-from-flush, 429 retry-in-place, terminal-status propagation, reissue exhaustion, the exact wire-request count against the retry budget, and five malformed stats payloads. - Node: **19 LSM tests passing**; `cargo check`, `npm run build`, `npm run tsc`, `npm run lint`, `npm run docs` all clean. - Python: `ruff format --check` and `ruff check` clean. - Java formatting: `./mvnw -pl lancedb-core spotless:apply` and `spotless:check` both clean under a JDK 11 toolchain. ## Note: spotless needs a pre-16 JDK `./mvnw spotless:apply` fails on JDK 16+ with `JCTree$JCImport.getQualifiedIdentifier()` — google-java-format 1.7, pinned at `java/pom.xml:34`, predates JDK 16's compiler API change. **This is pre-existing** and reproduces on a pristine `main` checkout. It is not a blocker, just a toolchain requirement. Spotless was run against these sources under JDK 11 and both `spotless:apply` and `spotless:check` pass on the whole module: ```shell JAVA_HOME=/path/to/jdk11 ./mvnw -pl lancedb-core spotless:apply ``` Bumping the plugin so it works on modern JDKs is still worth doing, but separately from this PR. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com> |

feat: refresh_column_async returns a job handle (#3939)
Mirrors create_index's dual surface: the blocking refresh_column keeps
returning {rows_filled, version}, and refresh_column_async returns the
same
Job handle create_index uses, running the refresh as an in-process task.
Invalid input is reported by the submitting call rather than by the job.

feat: refresh computed columns (#3938)
table.refresh_column("doubled") fills the rows of a declared column that
hold no value, in two passes per fragment: the first scans only the
unfilled
live rows to count exact gains and decide staging, the second streams
the
fragment's physical rows into a standalone column file published in one
DataReplacement -- committed under the dataset's own session -- so peak
memory is bounded by a scan batch. A row that holds a value keeps it;
deleted and already-filled rows never reach the expression, so a poison
value in them cannot fail the refresh. Refresh refuses under an LSM
write
spec, including the mem-wal catch-up flag that outlives unset and marks
retained SSTable rows.

feat: declare computed columns by SQL expression (#3937)
add_columns().computed("doubled", "x * 2") stores the expression in
field
metadata and commits the column empty; a later refresh fills it. Type
and
inputs are derived from the expression.
The declaration stays authoritative for its lifetime: writes that would
give
the column a value (append, update, merge, SQL insert), schema changes
that
would break the stored expression or reshape its output, metadata edits,
volatile expressions, declaration metadata arriving through any path but
the
validated declare call, and LSM write specs in either order against
latest
committed state are all refused. The LSM check also refuses on the
mem-wal
catch-up feature flag, which outlives unset and marks retained SSTable
rows.
Simultaneous declare/install interleavings conflict at commit via
lance's
mem-wal rule (lance#8539). Local tables only.

fix(node): preserve nested Arrow data across versions (#3900)
<!-- lance-gatekeeper-fix:v1 agent=613a074d606e626c5169d601373a32d8 generation=1 --> ## Root cause When LanceDB accepted an Arrow table created by a different installed Arrow package, its compatibility sanitizer rebuilt each Data node without converting the foreign type or preserving nested children. It also dropped the separate dictionary vector payload and did not preserve identity shared by dictionary schema types, vector wrappers, or growing dictionary chunks. ## Fix Recursively sanitize nested Arrow data types and child data. Use one table-scoped sanitization context to rebuild and memoize source type objects, dictionary vectors, and Data nodes in the local Arrow realm, preserving all identities required by Arrow IPC. Add Arrow 15 through 18 regressions for list serialization, ordinary dictionaries, dictionaries shared across fields and batches, growing dictionaries, and IPC round trips. ## Validation - pnpm test __test__/arrow.test.ts --runInBand (188 passed) - pnpm lint - pnpm build - pnpm test --runInBand (706 passed, 5 skipped) - pnpm run docs Fixes #2256 --------- Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com> |

fix(node): cover offset pagination in search (#3814)
## Summary - add Node regression coverage for vector-search offset pagination - add equivalent coverage for full-text search - compare later pages with the corresponding complete-result slice and assert page sizes ## Root cause The historical query path requested only the user limit from nearest-neighbor or full-text search before applying the offset, so a page became empty when its offset reached that limit. The production query path on current main already incorporates the later fix from #2592; this change adds the missing Node binding coverage for the still-open report and protects both affected APIs from regression. ## Validation - corepack pnpm build - corepack pnpm test -- query.test.ts --runInBand --testNamePattern="Search pagination" - corepack pnpm lint-ci - corepack pnpm tsc - corepack pnpm run docs Fixes #2229 <!-- lance-gatekeeper-fix:v1 agent=8ba8b18a18260a68a3e605d1bbfa518e generation=1 --> Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com> |

fix(node): cover non-nullable embedding schema append (#3835)
## Summary - Add an issue-specific regression for appending generated embeddings to an empty table with a non-nullable vector field. - Verify the custom embedding function produces the declared Float64 vectors and both appended rows are readable. ## Root cause In v0.4.19, records without a vector value were materialized against the explicit schema before embeddings were inserted. Apache Arrow inferred the generated batch vector field as nullable while the table retained the user-provided non-nullable field, then rejected the mismatched schemas. The current conversion path excludes the generated field from the initial record conversion and realigns the completed batch to the stored schema after embedding, but the reported empty-table append sequence lacked permanent regression coverage. ## Validation - `pnpm exec biome format --write __test__/embedding.test.ts` - `pnpm lint-ci` - `pnpm test -- --runInBand __test__/embedding.test.ts` (12 passed, 1 skipped integration test) - `pnpm build` - `pnpm run docs` Fixes #1281 <!-- lance-gatekeeper-fix:v1 agent=6b7270aeb92e6b6c6f5b45022fa83f6a generation=1 --> --------- Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com> |

fix(node): require compatible Node.js types (#3829)
## Summary - require Node.js 18-compatible type declarations when TypeScript consumers install them - keep the type peer optional for JavaScript-only consumers - add a regression test tying the Node type peer range to the supported runtime ## Root cause LanceDB requires Node.js 18 or newer, and its public types expose Apache Arrow declarations that import built-ins through the node: scheme. The package did not declare a matching @types/node peer requirement, so npm accepted projects pinned to Node 12 declarations and TypeScript then reported that node:stream and node:fs/promises did not exist. ## Validation - pnpm lint - pnpm build - pnpm run docs - pnpm test --runInBand (678 passed, 5 skipped) - packed-package consumer probe rejects @types/node 12.20.55 and installs with @types/node 18.19.130 Fixes #1713 <!-- lance-gatekeeper-fix:v1 agent=7a2b68f3daad20bed9e46cb8892d6e6c generation=1 --> Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com> |

test(node): cover remote table server errors (#3841)
## Summary - add a public Node API regression test for JSON server errors from remote table operations - verify countRows reports the server message instead of an ArrayBuffer decoding TypeError ## Root cause and fix The former TypeScript remote HTTP client passed an Axios-decoded JSON error object to TextDecoder, which masked the server response with an ArrayBuffer TypeError. The current Rust-backed remote client consumes non-success response bodies as text and propagates them through the Node error chain. This test exercises that corrected path through countRows and prevents the original failure from regressing. ## Validation - pnpm build - pnpm lint-ci - pnpm test --runInBand __test__/remote.test.ts - pnpm run docs Fixes #825 <!-- lance-gatekeeper-fix:v1 agent=91591c3d6b065796e6166664ef638aa7 generation=1 --> Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com> |

## Summary - add an end-to-end regression for schemas created by a different Apache Arrow package instance - cover seeded table creation, filtered scanning, and Float64 vector search across Arrow 15–18 ## Root cause Apache Arrow's runtime identity checks historically rejected schemas created by another installed Arrow instance, producing the constructor failures reported in the issue. LanceDB's peer dependency and foreign-schema sanitization now handle that boundary, but the complete reported workflow was only covered by separate unit tests. This regression keeps the repaired behavior protected end to end. ## Validation - `pnpm exec jest --runInBand __test__/table.test.ts` (281 passed) - `pnpm lint-ci` - `pnpm build` - `pnpm run docs` Fixes #882 <!-- lance-gatekeeper-fix:v1 agent=43b19dea581cfbc83ee1e9ed21a335a6 generation=1 --> Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com> |

## Summary - cover explicit FixedSizeList schemas populated from Float32Array values - verify the original vector.0 failure stays fixed across Arrow 15, 16, 17, and 18 ## Root cause and fix In v0.16, schema subset inference treated typed-array vectors as nested objects and looked up numeric paths such as vector.0, which do not exist in a FixedSizeList schema. Current typed-array handling correctly recognizes ArrayBuffer views as vector values instead of traversing their elements. This change adds the missing regression coverage for the reported explicit-schema path so that behavior cannot regress unnoticed. ## Validation - pnpm test __test__/arrow.test.ts --runInBand - pnpm lint - pnpm build - pnpm run docs - pnpm test --runInBand (681 passed, 5 skipped) Fixes #2134 <!-- lance-gatekeeper-fix:v1 agent=1d548cb70f6df110ce0a5b119395b52a generation=1 --> Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com> |

feat: create_index returns a Job handle (#3742)
IndexBuilder::execute now returns a Job with wait and cancel methods. Local tables build the index synchronously and return an already-done job. Remote tables read the job id the server returns from create_index and track it through the /v1/jobs API: wait polls describe until the job reaches a terminal state and cancel posts a cancellation. Servers that return no job id yield a done job, so behavior against older servers is unchanged. The job id is not exposed on the handle. The Python and TypeScript bindings keep their current signatures and discard the handle; exposing Job there is left to follow-ups. --------- Co-authored-by: Claude Fable 5 <noreply@anthropic.com> |

feat(fts): support custom stop-word lists (#3734)
## What Expose custom FTS stop-word lists in the Python and TypeScript public APIs, including their standalone tokenize helpers and remote index creation. This PR supports concrete string lists only. It does not add file or LanceDB-table stop-word sources. ## Why Rust already exposes Lance's custom stop-word list option. The Python and TypeScript APIs did not pass it through, and local index details did not retain the full tokenizer parameters needed by index-backed tokenization after reopening a table. ## How - Add `custom_stop_words` / `customStopWords` to the Python and TypeScript FTS and tokenize options. - Preserve `None` / `undefined`, empty lists, and list contents without normalization. - Load the persisted FTS segment parameters when returning local index details. - Serialize the concrete list in remote create-index requests. - Keep Python and TypeScript tests thin; behavior, persistence, query tokenization, and remote JSON coverage live primarily in Rust. ## Validation - `cargo check --quiet --features remote --tests --examples` - `cargo clippy --quiet --features remote --tests --examples` - `cargo test --quiet --features remote --tests` - Python extension rebuild with `uv` and `maturin` - Targeted Python tests: 4 passed - Python `ruff format --check` and `ruff check` - TypeScript build, typecheck, Biome lint, generated docs, and targeted tests --------- Co-authored-by: Yang Cen <yangcen@Yangs-Mac-mini.local> |

feat(query): add use_lsm to read MemWAL LSM data (#3489)
## What
MemWAL LSM **read** support. When a table has an LSM write spec
(`set_lsm_write_spec`), `merge_insert` upserts live in the MemWAL
active/frozen memtables and flushed SSTables until an external
compaction merges them into the base table, so a normal scan returns
**stale** data. This routes reads through Lance's `LsmScanner` so
queries also surface that in-flight data, deduplicated by primary key
(newest generation wins).
## How
- Adds a **`use_lsm: Option<bool>`** query flag, symmetric with the
`merge_insert` flag:
- **unset** — auto-route through the LSM scanner when the table carries
a write spec
- **`use_lsm(true)`** — force the LSM path; error if there is no spec
- **`use_lsm(false)`** — read the base table only (the escape hatch)
- Plain scan, single-column full-text search, and single-vector ANN all
run through one `LsmScanner` (assembled from on-disk shard manifests
plus the cached writer's in-memory memtables), so a `where` predicate is
honored as a **prefilter** uniformly — including for vector search.
- **Compaction-aware snapshots:** an SSTable generation is dropped only
once it is both compacted into the base table and covered by the arm's
base-index catch-up (`index_catchup`); plain scans use the compaction
watermark alone.
- Query shapes the scanner cannot honor hard-error with guidance to set
`use_lsm(false)`: hybrid, multi/binary vectors, `with_row_id`,
reranking, `order_by`, dynamic/Substrait projection or filters,
`distance_range`, `use_index(false)`, postfilter, take-by-row-id/offset,
reads from a time-traveled version, and an unmaintained or ambiguous
(multiple) FTS/vector index. Namespace-pushdown queries fall back to
local execution when a spec is present; WAL-only writers are handled.
- Exposed across the Rust core and the Python (`use_lsm`) and TypeScript
(`useLsm`) bindings, including `TakeQuery`.
Rebased from Lance `7.2.0-beta.3` to `10.0.0-beta.3`.

feat(fts): add block size configuration (#3691)
## What changed - add `block_size` to Python FTS configuration and the deprecated local/remote helpers - add `blockSize` to the TypeScript FTS options and propagate it through the NAPI binding - serialize the value as `block_size` for remote index creation - document the existing Rust builder API and generate the TypeScript API reference - add local, remote, metadata, search, and invalid-value regression coverage ## Why Lance supports configuring the number of documents per compressed FTS posting block, but LanceDB's Python and TypeScript APIs did not expose the setting. This made the experimental FTS V3 layout unavailable through those clients and allowed the value to be dropped before index creation. ## How it works The default remains `128`. Supported values are `128` and `256`; selecting `256` uses the experimental FTS V3 format. Invalid values are rejected by the Lance builder and surfaced as Python or JavaScript errors. ## Validation - `cargo check --quiet --features remote --tests --examples` - `cargo +1.94.0 clippy --quiet --features remote --tests --examples -- -D warnings` - targeted Rust local and remote index tests - Rust doctests: 34 passed - Python Ruff checks, doctest, and targeted local/remote tests: 5 passed - TypeScript build, Biome lint, generated docs, and targeted Jest tests: 9 passed - `git diff --check` ## Limitations The Java client remains unchanged because its external remote REST model does not currently expose `block_size`.

fix(node): sanitize Map fields across Arrow versions (#3650)
## Summary - reconstruct foreign Arrow Map schemas from their single sanitized entries field - reject malformed Map types with anything other than one child - preserve the complete Map schema and `keysSorted` value through empty-table creation and IPC round trips across Arrow 15–18 ## Testing - `./node_modules/.bin/jest --runInBand __test__/arrow.test.ts __test__/sanitize.test.ts` - `pnpm lint` - `pnpm build` - `pnpm run docs` Fixes #2337 |
