+name: lancedb-branch-ops
+description: Branch management for LanceDB tables via the REST API. Use this skill whenever someone wants to create, delete, list, or switch branches on a LanceDB table — or needs to make sure a write (metadata update, index build, etc.) lands on a specific branch instead of main. Invoke it even without the word "branch" if context makes clear they want an experimental copy of a table, want to isolate changes, or want to confirm a mutation didn't touch main. Covers: branches/list, branches/create, branches/delete, and passing "branch" in describe/update_field_metadata/create_index to target a non-main version.
+---
+
+## Goal
+
+Manage branches on a LanceDB table: list what exists, create new ones, delete stale ones, and direct read/write operations at a specific branch without touching main.
+
+## Step 0: Establish the connection
+
+Use the `lancedb-connect` skill to resolve the base URL and auth headers (`x-api-key`, `x-lancedb-database`). Skip this only if the connection is already known from the current conversation.
+
+All examples below use `{base_url}` — substitute the resolved endpoint and include the auth headers on every request.
+
+## The branch model (important)
+
+LanceDB branches are named snapshots that diverge from the table's current state at creation time. There is **no checkout command** — you never switch the whole table to a branch. Instead, you **pass `"branch": "<name>"` in the request body** of any operation to target that branch. Omitting the key (or sending an empty body) always targets main.
+
+`branches/list` returns only non-main branches. Main always exists and is not listed.
+
+## List branches
+
+```http
+POST {base_url}/v1/table/{table_id}/branches/list
+Content-Type: application/json
+
+{}
+```
+
+Response:
+```json
+{
+  "branches": {
+    "experiment-reindex": {"parentVersion": 1, "createAt": 1782506085, "manifestSize": 1029}
+  }
+}
+```
+
+If `branches` is `{}`, the table has no branches besides main.
+
+## Create a branch
+
+```http
+POST {base_url}/v1/table/{table_id}/branches/create
+Content-Type: application/json
+
+{"name": "experiment-reindex"}
+```
+
+HTTP 200 with `{}` body = success. The branch is created off the table's current state on main.
+
+Verify by calling `branches/list` and confirming the new name appears.
+
+## Delete a branch
+
+```http
+POST {base_url}/v1/table/{table_id}/branches/delete
+Content-Type: application/json
+
+{"name": "stale-2024"}
+```
+
+HTTP 200 with `{}` body = success. Only the branch pointer is removed — main and all row data remain intact.
+
+Verify by calling `branches/list` (name gone) and `describe` with no branch param (main still responds).
+
+## Operate on a specific branch
+
+Pass `"branch": "<name>"` in the body of any operation to scope it to that branch:
+
+**Read schema on a branch:**
+```http
+POST {base_url}/v1/table/{table_id}/describe
+Content-Type: application/json
+
+{"branch": "wip-branch"}
+```
+
+**Write metadata to a branch (not main):**
+```http
+POST {base_url}/v1/table/{table_id}/update_field_metadata
+Content-Type: application/json
+
+{
+  "branch": "wip-branch",
+  "updates": [
+    {
+      "path": "category",
+      "metadata": {"lancedb:description": "Product category label."},
+      "replace": false
+    }
+  ]
+}
+```
+
+**Build an index on a branch:**
+```http
+POST {base_url}/v1/table/{table_id}/create_index
+Content-Type: application/json
+
+{
+  "branch": "wip-branch",
+  "column": "category",
+  "index_type": "BTREE"
+}
+```
+
+## Verifying isolation
+
+After writing to a branch, always confirm the change did NOT land on main:
+
+```bash
+# Should show the new metadata
+curl -s -X POST {base_url}/v1/table/{table_id}/describe \
+  -H "x-api-key: <key>" -H "x-lancedb-database: <db>" \
+  -H "content-type: application/json" \
+  -d '{"branch": "wip-branch"}'
+
+# Should NOT show the new metadata
+curl -s -X POST {base_url}/v1/table/{table_id}/describe \
+  -H "x-api-key: <key>" -H "x-lancedb-database: <db>" \
+  -H "content-type: application/json" \
+  -d '{}'
+```

+name: lancedb-column-metadata
+description: Column metadata authoring for LanceDB tables via the REST API. This skill is required for tasks like writing field descriptions, setting tags on columns (field_type, model, project_id, version), classifying columns as embeddings vs labels vs eval metrics, or grouping versioned columns into logical families — because it has the API integration needed to read the schema and persist metadata back. Invoke whenever someone wants to document, annotate, tag, or classify what their table columns ARE. Trigger even without an explicit "LanceDB" mention, as long as the context is column-level documentation or tagging for an ML or vector database table.
+metadata:
+  short-description: Write column descriptions, tags, and logical groupings to a LanceDB table
+---
+
+## Overview
+
+This skill authors column-level metadata for a LanceDB table. It connects to a LanceDB deployment over its REST API, inspects the table schema, generates appropriate metadata, and writes it back.
+
+## Step 0: Establish the connection
+
+Use the `lancedb-connect` skill (invoke it via the Skill tool) to resolve the base URL and auth headers (`x-api-key`, `x-lancedb-database`) for whichever deployment the user is working against — enterprise/self-hosted or a local dev server. Skip it only if the connection details are already established in the conversation.
+
+All examples below use `{base_url}` — substitute the resolved endpoint and include the resolved headers on every request.
+
+## Metadata keys
+
+All metadata uses namespaced keys:
+
+| Key | Purpose | Example value |
+|-----|---------|---------------|
+| `lancedb:description` | Human-readable explanation of what the column contains | `"CLIP ViT-L/14 image embedding, L2-normalized (768-dim)"` |
+| `lancedb:tag:<name>` | Flexible key-value tag; the suffix names the tag category | `lancedb:tag:field_type: "embedding"`, `lancedb:tag:model: "clip"`, `lancedb:tag:project_id: "foo"` |
+| `lancedb:logical-column` | Logical group/family this column belongs to | `"clip_features"` |
+
+Tags are open-ended — use whatever key suffix and value make sense given the user's intent. The tag suffix should describe *what is being classified* (e.g., `field_type`, `model`, `project_id`) and the value describes *how*.
+
+## Step 1: Resolve the table identifier
+
+You need:
+- **Table name** (required) — e.g., `my_table` or `my_namespace.my_table`
+- **Database name** — ask if not provided and not inferable from context; it goes in the `x-lancedb-database` header, never in the URL path
+
+The table identifier in the URL path is typically `table_name` for a top-level table, or `namespace$table_name` if the table lives in a namespace. The API accepts a `delimiter` query parameter to parse compound identifiers (default `$`).
+
+## Step 2: Describe the table
+
+```http
+POST {base_url}/v1/table/{table_id}/describe
+Content-Type: application/json
+
+{}
+```
+
+The response contains `schema.fields` — an array of field objects:
+
+```json
+{
+  "schema": {
+    "fields": [
+      {
+        "name": "clip_embedding_v3",
+        "type": { "type": "FixedSizeList", "fields": [...], "listSize": 768 },
+        "nullable": true,
+        "metadata": { "lancedb:description": "..." }
+      }
+    ]
+  }
+}
+```
+
+Each field has:
+- `name` — field name
+- `type` — Arrow data type (check `type.type` for the type string)
+- `nullable` — boolean
+- `metadata` — existing key-value metadata (read this before writing to avoid redundant updates)
+
+For struct/nested fields, recurse into `type.fields` and represent them as dot-notation paths (e.g., `parent.child`).
+
+If the user hasn't specified which columns to update, work with all columns.
+
+## Step 3: Generate metadata
+
+Decide what to generate based on the user's request.
+
+### Writing descriptions (`lancedb:description`)
+
+Base descriptions on:
+- The column name and Arrow type (e.g., `FixedSizeList` of floats → likely an embedding)
+- User-supplied context (upstream pipeline, sample values, domain knowledge)
+- Name patterns: `_embedding`/`_vec`/`_embed` → vector; `_label`/`_class` → label; `_score`/`_eval`/`_metric` → evaluation metric
+
+Be specific and concise. Good: `"Sentence-BERT embedding of the query text (768-dim)."` Not: `"An embedding column."`
+
+### Tagging columns (`lancedb:tag:<name>`)
+
+Choose tag key names that match what the user asked to annotate. Common patterns:
+
+- Semantic field type → `lancedb:tag:field_type: "embedding"` / `"text"` / `"image"` / `"label"` / `"eval"` / `"id"` / `"metadata"`
+- Model or source → `lancedb:tag:model: "clip"` / `"bert"` / `"vit"`
+- Project affiliation → `lancedb:tag:project_id: "<name>"`
+- Version → `lancedb:tag:version: "v3"` (and `lancedb:tag:latest: "true"` for the newest)
+
+Use Arrow type as a hint: `FixedSizeList` + float → embedding; `Utf8`/`LargeUtf8` → text; `Binary` → image or blob.
+
+Multiple tags on the same column are fine — each is a separate key.
+
+### Grouping into logical columns (`lancedb:logical-column`)
+
+Look for naming patterns across columns:
+- `clip_v1`, `clip_v2`, `clip_v3` → logical column `"clip"`, latest is `v3`
+- `text_embed_20240101`, `text_embed_20240601` → logical column `"text_embed"`, latest is the most recent date suffix
+
+Write `lancedb:logical-column` on all members of a group. Mark the newest with `lancedb:tag:latest: "true"` (in addition to its version tag).
+
+## Step 4: Write the metadata
+
+```http
+POST {base_url}/v1/table/{table_id}/update_field_metadata
+Content-Type: application/json
+
+{
+  "updates": [
+    {
+      "path": "clip_v3",
+      "metadata": {
+        "lancedb:description": "CLIP ViT-L/14 image embedding, L2-normalized (1024-dim).",
+        "lancedb:tag:field_type": "embedding",
+        "lancedb:tag:model": "clip",
+        "lancedb:tag:version": "v3",
+        "lancedb:tag:latest": "true",
+        "lancedb:logical-column": "clip"
+      },
+      "replace": false
+    },
+    {
+      "path": "clip_v2",
+      "metadata": {
+        "lancedb:description": "CLIP ViT-B/32 image embedding (768-dim), superseded by v3.",
+        "lancedb:tag:field_type": "embedding",
+        "lancedb:tag:model": "clip",
+        "lancedb:tag:version": "v2",
+        "lancedb:logical-column": "clip"
+      },
+      "replace": false
+    }
+  ]
+}
+```
+
+Rules:
+- **Use `"replace": false`** (merge) by default — this preserves existing metadata the user didn't ask to change
+- Use `"replace": true` only if the user explicitly asks to overwrite all existing metadata on a column
+- Set a value to `null` to delete a specific key
+- Batch all updates in a single request when possible
+
+The response includes `version` (new table version) and `fields` (the updated metadata per field).
+
+## Step 5: Confirm
+
+Report back:
+- Which columns were updated and what was written
+- The new table version number
+- Any columns skipped (e.g., already had up-to-date metadata)
+

+
+## Quick examples
+
+**"Write descriptions for all columns in the `product_embeddings` table"**
+1. POST `/v1/table/product_embeddings/describe` → get all fields
+2. Generate a `lancedb:description` for each column based on name + type
+3. POST `update_field_metadata` with descriptions
+4. Report
+
+**"Tag the columns in `model_outputs` with their field type and model"**
+1. Describe `model_outputs`
+2. For each field, classify by name + Arrow type → set `lancedb:tag:field_type` and `lancedb:tag:model` where applicable
+3. POST `update_field_metadata`
+4. Report
+
+**"Group the feature columns in `training_features` into logical families and mark the latest version"**
+1. Describe the table
+2. Find version patterns → assign `lancedb:logical-column` and `lancedb:tag:version`; mark newest with `lancedb:tag:latest: "true"`
+3. POST `update_field_metadata`
+4. Show the grouping

+description: Resolve how to connect to a LanceDB deployment over the REST API — figure out the base URL, API key, and database header. Use this before making any REST requests to a LanceDB table, whenever the endpoint or auth setup is not already known. Also useful on its own when someone asks how to connect, authenticate, or curl their LanceDB instance.
+metadata:
+  short-description: Resolve the base URL and auth headers for a LanceDB deployment
+---
+
+## Goal
+
+Produce two things every REST request needs:
+
+1. **Base URL** — the endpoint
+2. **Headers** — `x-api-key`, and usually `x-lancedb-database`
+
+## Resolution steps
+
+1. If the user already gave a URL and API key (or said which environment they're working against), use that.
+2. Otherwise, look for credentials already available in the environment:
+   - Env vars like `LANCEDB_URI` / `LANCEDB_HOST` / `LANCEDB_API_KEY`
+   - A LanceDB endpoint already running or port-forwarded locally (the REST default port is 2333, i.e. `http://localhost:2333`)
+3. If you didn't find both pieces, ask the user directly: **"What's your LanceDB endpoint's URL, and what's your API key?"** Also ask which database to use if it isn't obvious. Don't guess or probe further — the user knows their deployment.
+
+## Validating the connection
+
+Make a cheap authenticated request and check the status:
+
+```bash
+curl -s -w "\n%{http_code}" "{base_url}/v1/table/?limit=1" \
+  -H "x-api-key: <key>" \
+  -H "x-lancedb-database: <database>"
+```
+
+- `200` — connection, key, and database header all good
+- `401` — API key missing or wrong
+- `400` mentioning a database header — this deployment expects `x-lancedb-database`
+
+## Non-REST equivalents
+
+If the caller would rather use the SDK or CLI than raw REST, the same credentials work:
+
+- Python SDK: `lancedb.connect("db://<database>", api_key="<key>", host_override="<base_url>")`
+- `lancedb` CLI: a `[profiles.<name>]` entry in `~/.lancedb/config.toml` with `http_server_url`, `api_key`, `database`

-!!! note
-    The current Java namespace API exposes index type, index name, distance type, and full text search tokenizer options.
-    IVF training parameters such as `num_partitions` are not exposed by `CreateTableIndexRequest` yet.
-    To make those configurable from Java, the namespace API must add those fields first.

-# Function: instrumentLanceDbMetrics()
-
-```ts
-function instrumentLanceDbMetrics(meterProvider?): boolean
-```
-
-Register LanceDB metrics as OpenTelemetry observable instruments.
-
-Installs a process-global metrics recorder and creates one observable
-instrument per LanceDB metric (currently object store request counts, bytes,
-latency, errors, and throttles) on the given (or global) `MeterProvider`. The
-configured `MetricReader` then collects them on its own schedule.
-
-Counters and gauges map directly to observable counters/gauges. Because
-OpenTelemetry has no asynchronous histogram instrument, each histogram is
-exported Prometheus-style as cumulative `le` bucket counts (`<name>_bucket`,
-with an `le` attribute) plus `<name>_count` and `<name>_sum`.
-
-Requires `@opentelemetry/api` (a dependency) and, to actually export, an
-OpenTelemetry SDK such as `@opentelemetry/sdk-metrics`.
-
-## Parameters
-
-* **meterProvider?**: `MeterProvider`
-    The provider to register instruments on. Defaults to the
-    global provider from `@opentelemetry/api`.
-
-## Returns
-
-`boolean`
-
-`true` if the recorder is installed and instruments are registered.
-  `false` if a different `metrics` recorder is already installed in this
-  process (only one global recorder is permitted), in which case a warning is
-  emitted and no instruments are created. Calling this more than once is safe;
-  instruments are created only on the first successful call.

-description: Use when writing, reviewing, debugging, or documenting LanceDB pipelines in Python or TypeScript, especially code that should work across local LanceDB OSS tables and remote LanceDB Enterprise/Cloud tables. Helps avoid non-portable full-table materialization, choose idiomatic query/search patterns, apply LanceDB performance defaults for ingestion, indexing, filtering, and diagnostics, and resolve connections to the remote server for Enterprise-only operations such as jobs.
---
-
-# Building LanceDB Pipelines
-
-Use this skill to produce LanceDB pipelines that are portable between local and remote tables (for LanceDB Enterprise/Cloud) and idiomatic for the selected SDK.
-
-## LanceDB Table Modes
-
-LanceDB has two common execution modes:
-
- **Local table**: embedded, open source, in-process LanceDB. The client opens data from a local path or object storage URI and executes queries in the application process.
- **Remote table**: LanceDB Enterprise/Cloud table opened through a `db://...` URI. The data may be very large, commonly backed by object storage, and queried through a remote service.
-
-Do NOT assume local-only table helpers exist on remote tables. If the user asks for LanceDB Enterprise, Cloud, `db://...`, production remote access, or a remote table, focus on the remote table path: use `search()` / `query()`, keep reads bounded with `select()` and `limit()`, and avoid table-level full materialization APIs.
-
-## Workflow
-
-1. Identify the SDK: Python, TypeScript, or both.
-2. Identify the table mode: local/embedded OSS, remote Enterprise/Cloud, or portable across both. If the user says "LanceDB Enterprise", choose the remote table path. If the task involves jobs in any way (listing, inspecting, creating, or canceling jobs), it is always the remote path and requires a remote server connection — see "Connecting to the LanceDB remote server" below before doing anything else.
-3. Read the matching language branch before writing or changing code:
-   - Python patterns: `references/python/patterns.md`
-   - Python API quick reference: `references/python/api_reference.md`
-   - Python performance guidance: `references/python/performance.md`
-   - TypeScript patterns: `references/typescript/patterns.md`
-   - TypeScript API quick reference: `references/typescript/api_reference.md`
-   - TypeScript performance guidance: `references/typescript/performance.md`
-   - Column metadata authoring (both SDKs): `references/column_metadata.md`
-   - Branch operations (both SDKs): `references/branch_ops.md`
-   - Remote server connection resolution (jobs, raw REST): `references/remote_connect.md`
-   - Job operations REST API (list/describe/cancel/query_events): `references/remote_jobs.md`
-4. Start with `patterns.md` for the selected SDK. Read `api_reference.md` when choosing method names or return collectors. Read `performance.md` when the task involves ingestion, indexing, filtering, query tuning, diagnostics, or large datasets. Read `column_metadata.md` when the task is documenting, tagging, classifying, or grouping table columns (field descriptions, `lancedb:tag:*` tags, logical column families). Read `branch_ops.md` when the task involves branch lifecycle (list/create/delete), writing to a non-main branch, or verifying a change stayed off main. Read `remote_connect.md` when the task involves jobs or direct REST access to an Enterprise deployment, and `remote_jobs.md` for the job REST methods themselves (list, describe, cancel, query_events).
-5. For Python schemas, favor Pydantic models and validate records before writing. Use PyArrow schemas when Arrow-native, streaming, or highly dynamic data makes them materially better suited.
-6. Prefer `search()` or `query()` builders with explicit `select()` and `limit()` for reads.
-7. Avoid table-level full materialization in remote or portable code. This is the main local-vs-remote read pitfall.
-8. After a successful embedded OSS ingestion, call `table.optimize()`. Do not call it for Enterprise/Cloud; remote maintenance is automatic.
-9. For remote Enterprise/Cloud writes, never drop-then-reuse or `mode="overwrite"` the same table name — see "Enterprise: never drop-then-reuse the same table name" below. This is the main local-vs-remote write pitfall.
-10. If reviewing an existing file or repo, run `scripts/check_materialization.py` on the relevant paths and inspect each finding before editing.
-11. Cross-check unfamiliar or non-trivial API claims against the source tree instead of relying on memory.
-
-## Core Portability Rule
-
-Do not write code that assumes a local table API will exist on a remote table. Remote tables can be very large, so whole-table materialization helpers are intentionally unavailable or unsafe.
-
-This does **not** mean result conversion is forbidden. Bounded query/search result collection is normal:
-
- Python: `table.search(...).select([...]).limit(10).to_pandas()`
- TypeScript: `await table.search(...).select([...]).limit(10).toArray()`
-
-The unsafe pattern is table-level or unbounded collection, plus local-only dataset escape hatches in remote code:
-
- Python: `table.to_pandas()`, `table.to_arrow()`, `table.to_polars()`; `table.to_lance()` is local/OSS-only dataset access, not materialization
- TypeScript: `await table.toArrow()`, `await table.query().toArray()` without `limit()`
-
-## Enterprise: never drop-then-reuse the same table name
-
-LanceDB Enterprise/Cloud splits a **control plane** (DDL: create/drop/rename) from a **data plane** (query nodes that serve reads). Query nodes cache the resolved dataset for a table name for up to `table_cache_ttl` — **default 300 seconds (5 minutes)**. After you drop or overwrite a table, the control plane updates immediately but the data plane keeps serving the *old* dataset until that cache entry expires. During the window the two planes disagree.
-
-The failure this causes: you `drop_table("t")` then immediately `create_table("t", ...)` (or `create_table("t", ..., mode="overwrite")`). The DDL returns success, but every query against `t` returns **`500 Internal Server Error`** (the query node resolves the stale/deleted dataset), and a fresh `describe` may still show the *old* schema/version. It looks like your write silently failed; it didn't — the name is cached.
-
-**`mode="overwrite"` has the same problem** — it is a drop+create of the same name under the hood.
-
-Rules for portable Enterprise ingestion:
-
-1. **Never reuse a table name you just dropped/overwrote within the cache TTL.** Do not use `mode="overwrite"` to replace an existing Enterprise table in place.
-2. To (re)load data, **write to a fresh table name** (e.g. `<table>_v2`, or a run-stamped suffix). A brand-new name has no cached data-plane entry, so writes and reads work immediately.
-3. Before creating, `list_tables()` and **fail loudly if the name already exists** rather than overwriting — prompt for a new name.
-4. To land on a specific final name that is currently occupied by an old table: drop the old table, **wait out the TTL (~5 min), then `rename_table(fresh_name, final_name)`**. Renaming onto a name whose old dataset is still cached hits the same race, so the wait is mandatory. `rename_table` is a supported control-plane op.
-5. When you hand a table name back to a human, tell them which step still needs the propagation wait (usually: "the old `t` was dropped; run the rename in ~5 minutes").
-
-This is Enterprise/Cloud-specific. Local/OSS tables have no separate data plane, so `mode="overwrite"` and immediate same-name reuse are fine there.

-## Connecting to the LanceDB remote server
-
-LanceDB Enterprise/Cloud deployments are served by a server implementing the lance-namespace OpenAPI spec (<https://github.com/lance-format/lance-namespace/blob/main/docs/src/spec.yaml>). Every remote (`db://...`) connection talks to such a server, and some operations exist only there. In particular, **all operations around jobs (listing, inspecting, creating, or canceling jobs) run server-side** — there is no local/OSS equivalent. Before any job work, or any direct REST call to an Enterprise deployment, read `references/remote_connect.md` to resolve the base URL, credentials, and database header and to validate the connection. Then use the four job REST methods documented in `references/remote_jobs.md` (list, describe, cancel, query_events).

-# Branch Operations
-
-Manage branches on a LanceDB table: list what exists, create new ones, delete stale ones, and direct read/write operations at a specific branch without touching main. Use for branch lifecycle tasks, experimental/isolated table versions, targeting an operation at a non-main branch, or confirming a mutation did not affect main.
-
-Works on local/OSS and remote Enterprise/Cloud tables, except merging a branch into main, which is Enterprise-only.
-
-## The branch model (important)
-
-Branches are isolated, writable lines of history forked from another branch (or a specific version). Writes on a branch never affect `main`.
-
-There is **no global "switch branch" state** — you never repoint the whole table at a branch. Instead, **operations are scoped by which table handle you use**:
-
- The handle you got from `open_table(name)` / `openTable(name)` targets `main`.
- `branches.create(...)` and `branches.checkout(...)` return a **new table handle scoped to that branch**. Every read/write on that handle (add, update, `update_field_metadata`, `create_index`, search, …) lands on the branch.
- The original main handle is unaffected — keep it around to verify isolation.
-
-`branches.list()` returns only non-main branches. Main always exists and is not listed.
-
-## Python
-
-`table.branches` is a property returning the branch manager; `table.current_branch()` tells you what a handle is scoped to (`None` = main).
-
-```python
-table = db.open_table("products")            # scoped to main
-
-# list — dict of name -> metadata (parent_branch, parent_version, ...); {} = only main
-table.branches.list()
-
-# create: forks from main by default and returns a handle scoped to the new branch
-exp = table.branches.create("experiment-reindex")
-exp = table.branches.create("exp2", from_ref="main", from_version=None)  # optional fork point
-
-# checkout an existing branch -> branch-scoped handle
-wip = table.branches.checkout("wip-branch")
-# with version= it pins to that version (read-only detached view); omit to track latest, writable
-
-# operate on the branch simply by using its handle
-wip.update_field_metadata(
-    {"path": "category", "metadata": {"lancedb:description": "Product category label."}}
-)
-wip.create_scalar_index("category")
-
-# delete: removes only the branch pointer; main and row data remain intact
-table.branches.delete("stale-2024")
-
-# alternatively, open a branch handle directly from the connection
-wip = db.open_table("products", branch="wip-branch")
-
-exp.current_branch()    # "experiment-reindex"
-table.current_branch()  # None (main)
-```
-
-Async: same shape — `table.branches` returns `AsyncBranches`; `await table.branches.create(...)` etc.
-
-## TypeScript
-
-`table.branches()` is an **async method** returning the `Branches` manager; `table.currentBranch()` returns the scoped branch or `null` for main.
-
-```typescript
-const table = await db.openTable("products"); // scoped to main
-const branches = await table.branches();
-
-// list — Record<string, BranchContents>; {} = only main
-await branches.list();
-
-// create: forks from main by default, returns a Table scoped to the new branch
-const exp = await branches.create("experiment-reindex");
-const exp2 = await branches.create("exp2", "main" /* fromRef */, undefined /* fromVersion */);
-
-// checkout an existing branch -> branch-scoped Table
-const wip = await branches.checkout("wip-branch");
-// with a version arg it pins (read-only detached view); omit to track latest, writable
-
-// operate on the branch simply by using its handle
-await wip.updateFieldMetadata([
-  { path: "category", metadata: { "lancedb:description": "Product category label." } },
-]);
-await wip.createIndex("category");
-
-// delete: removes only the branch pointer; main and row data remain intact
-await branches.delete("stale-2024");
-
-// alternatively, open a branch handle directly from the connection
-const wip2 = await db.openTable("products", { branch: "wip-branch" });
-
-exp.currentBranch();   // "experiment-reindex"
-table.currentBranch(); // null (main)
-```
-
-## Verifying isolation
-
-After writing to a branch, confirm the change did NOT land on main by reading through both handles:
-
-```python
-wip = table.branches.checkout("wip-branch")
-wip.update_field_metadata({"path": "category", "metadata": {"lancedb:description": "..."}})
-
-assert b"lancedb:description" in (wip.schema.field("category").metadata or {})
-assert b"lancedb:description" not in (table.schema.field("category").metadata or {})  # main untouched
-```
-
-Two handles on the same branch see each other's writes (e.g. `table.branches.create("exp")` and `db.open_table(name, branch="exp")`); main stays isolated.
-
-## Merging a branch into main (Enterprise only)
-
-Merge is available through the SDKs (`table.branches.merge(...)`) on **Enterprise tables only** — it is not supported on Cloud or local/OSS tables, which raise `NotSupported`.
-
-`merge` takes the branch to merge **from** and a `dry_run` flag. Both the SDK method and the underlying REST endpoint **actually merge by default** (`dry_run=False`); pass `dry_run=True` to only preview. A rejected merge is **not an exception** — it returns a result with `status="rejected"` rather than raising, so inspect the return value. Use `branches.diff(from_branch)` to inspect a branch's pending diff without attempting a merge.
-
-```python
-exp = "experiment-reindex"
-
-# preview only — returns status="ready" if it would merge cleanly
-preview = table.branches.merge(exp, dry_run=True)
-
-# actually merge (default)
-result = table.branches.merge(exp)
-if result["status"] == "merged":
-    print("landed at", result["mainVersionAfter"])
-elif result["status"] == "rejected":
-    print(result["diff"]["mergeBlockers"])   # why it was refused
-
-# inspect a branch's pending diff without merging
-diff = table.branches.diff(exp)
-```
-
-Async: `await table.branches.merge(exp)`, `await table.branches.diff(exp)`.
-
-```typescript
-const branches = await table.branches();
-const exp = "experiment-reindex";
-
-// preview only (second arg is dryRun)
-const preview = await branches.merge(exp, true);
-
-// actually merge (default)
-const result = await branches.merge(exp);
-if (result.status === "merged") {
-  console.log("landed at", result.mainVersionAfter);
-} else if (result.status === "rejected") {
-  console.log(result.diff.mergeBlockers);
-}
-
-const diff = await branches.diff(exp);
-```
-
-The result is the wire JSON, containing `status` (`ready` on a passing dry run, `merged` on success, `rejected` when refused — also `notImplemented`/`unknown`), the branch `diff` (including `mergeBlockers` explaining any rejection), a `preview` of the columns that would be promoted, and — after a real merge — `mainVersionAfter`.
-
-### Merge preconditions
-
-Merge only **promotes newly added columns** onto main; it does not replay arbitrary commits. Practically, a branch is mergeable only if it has **exactly one commit since it was created, and that commit added a column**. The merge is rejected (`status: "rejected"`, with `mergeBlockers` set) if:
-
- the branch was forked from another branch rather than directly from main
- main has advanced since the branch was forked
- the branch's rows changed since the fork (row counts must match main exactly)
- the branch removed columns or changed a column's type/nullability
- the branch added no columns (index-only changes are not merged)
-
-### Adding a column in a single commit
-
-Because the branch must contain just one column-adding commit, add the column with its values in one operation rather than add-then-backfill:
-
-1. **SQL transformation** — `add_columns` with a SQL expression computed from existing columns, so the column lands populated in one commit.
-2. **Precompute the values** — compute the column's values externally, then add the fully-populated column in a single operation (e.g. via `merge_insert`/`add_columns` with the data ready).
-3. **Lance-format-level data evolution (pylance)** — use Lance's data evolution with backfill, documented at <https://lance.org/guide/data_evolution/#with-data-backfill>.

-# Column Metadata Authoring
-
-Write column-level descriptions, tags, and logical groupings onto a LanceDB table's schema. Use this when the user wants to document, annotate, tag, or classify what their table columns ARE (embeddings vs labels vs eval metrics, model provenance, version families, etc.).
-
-Works on local/OSS and remote Enterprise/Cloud tables alike — read the schema through the table handle, write through `update_field_metadata` (Python) / `updateFieldMetadata` (TypeScript).
-
-## Metadata key conventions
-
-All metadata uses namespaced keys:
-
-| Key | Purpose | Example value |
-|-----|---------|---------------|
-| `lancedb:description` | Human-readable explanation of what the column contains | `"CLIP ViT-L/14 image embedding, L2-normalized (768-dim)"` |
-| `lancedb:tag:<name>` | Flexible key-value tag; the suffix names the tag category | `lancedb:tag:field_type: "embedding"`, `lancedb:tag:model: "clip"`, `lancedb:tag:project_id: "foo"` |
-| `lancedb:logical-column` | Logical group/family this column belongs to | `"clip_features"` |
-
-Tags are open-ended — use whatever key suffix and value make sense given the user's intent. The tag suffix should describe *what is being classified* (e.g., `field_type`, `model`, `project_id`) and the value describes *how*. Multiple tags on the same column are fine — each is a separate key. All values are strings.
-
-## Step 1: Read the schema and existing metadata
-
-Read existing metadata before writing, to avoid redundant updates.
-
-Python — `table.schema` (sync property; async: `await table.schema()`) returns a `pyarrow.Schema`. **Arrow field metadata is bytes-keyed in Python**:
-
-```python
-schema = table.schema
-for field in schema:
-    meta = field.metadata or {}  # dict[bytes, bytes], e.g. {b"lancedb:description": b"..."}
-    print(field.name, field.type, field.nullable, meta)
-```
-
-TypeScript — `await table.schema()` returns an Arrow `Schema`; field metadata is a `Map<string, string>`:
-
-```typescript
-const schema = await table.schema();
-for (const field of schema.fields) {
-  console.log(field.name, field.type, field.nullable, field.metadata); // Map
-  // field.metadata.get("lancedb:description")
-}
-```
-
-For struct/nested fields, recurse into the field's children and address them as dot-paths (e.g., `parent.child`).
-
-If the user hasn't specified which columns to update, work with all columns.
-
-## Step 2: Generate metadata
-
-Decide what to generate based on the user's request.
-
-### Descriptions (`lancedb:description`)
-
-Base descriptions on:
- The column name and Arrow type (e.g., `FixedSizeList` of floats → likely an embedding)
- User-supplied context (upstream pipeline, sample values, domain knowledge)
- Name patterns: `_embedding`/`_vec`/`_embed` → vector; `_label`/`_class` → label; `_score`/`_eval`/`_metric` → evaluation metric
-
-Be specific and concise. Good: `"Sentence-BERT embedding of the query text (768-dim)."` Not: `"An embedding column."`
-
-### Tags (`lancedb:tag:<name>`)
-
-Choose tag key names that match what the user asked to annotate. Common patterns:
-
- Semantic field type → `lancedb:tag:field_type: "embedding"` / `"text"` / `"image"` / `"label"` / `"eval"` / `"id"` / `"metadata"`
- Model or source → `lancedb:tag:model: "clip"` / `"bert"` / `"vit"`
- Project affiliation → `lancedb:tag:project_id: "<name>"`
- Version → `lancedb:tag:version: "v3"` (and `lancedb:tag:latest: "true"` for the newest)
-
-Use Arrow type as a hint: `FixedSizeList` + float → embedding; `Utf8`/`LargeUtf8` → text; `Binary` → image or blob.
-
-### Logical groupings (`lancedb:logical-column`)
-
-Look for naming patterns across columns:
- `clip_v1`, `clip_v2`, `clip_v3` → logical column `"clip"`, latest is `v3`
- `text_embed_20240101`, `text_embed_20240601` → logical column `"text_embed"`, latest is the most recent date suffix
-
-Write `lancedb:logical-column` on all members of a group. Mark the newest with `lancedb:tag:latest: "true"` (in addition to its version tag).
-
-## Step 3: Write the metadata
-
-Each update names a field by dot-path and carries a metadata map. Semantics (identical in both SDKs):
-
- **Merge by default** (`replace` omitted/false) — preserves existing metadata the user didn't ask to change
- `replace: true` swaps the field's entire metadata map — only if the user explicitly asks to overwrite
- A value of `None`/`null` deletes that specific key
- Batch all field updates into a single call when possible
- Returns the new table version
-
-Python (sync and async take one dict per field, as varargs):
-
-```python
-res = table.update_field_metadata(
-    {
-        "path": "clip_v3",
-        "metadata": {
-            "lancedb:description": "CLIP ViT-L/14 image embedding, L2-normalized (1024-dim).",
-            "lancedb:tag:field_type": "embedding",
-            "lancedb:tag:model": "clip",
-            "lancedb:tag:version": "v3",
-            "lancedb:tag:latest": "true",
-            "lancedb:logical-column": "clip",
-        },
-    },
-    {
-        "path": "clip_v2",
-        "metadata": {
-            "lancedb:description": "CLIP ViT-B/32 image embedding (768-dim), superseded by v3.",
-            "lancedb:tag:field_type": "embedding",
-            "lancedb:tag:model": "clip",
-            "lancedb:tag:version": "v2",
-            "lancedb:logical-column": "clip",
-        },
-    },
-)
-print(res.version)  # new table version

-# merge semantics: add a key, delete one via None, keep the rest
-table.update_field_metadata(
-    {"path": "clip_v2", "metadata": {"lancedb:tag:archived": "true", "lancedb:tag:latest": None}}
-)
-```
-
-(`replace_field_metadata` is deprecated — use `update_field_metadata`.)
-
-TypeScript (takes an array of `FieldMetadataUpdate`):
-
-```typescript
-const res = await table.updateFieldMetadata([
-  {
-    path: "clip_v3",
-    metadata: {
-      "lancedb:description": "CLIP ViT-L/14 image embedding, L2-normalized (1024-dim).",

-  },
-  {
-    path: "clip_v2",
-    metadata: {
-      "lancedb:description": "CLIP ViT-B/32 image embedding (768-dim), superseded by v3.",
-      "lancedb:tag:field_type": "embedding",
-      "lancedb:tag:model": "clip",
-      "lancedb:tag:version": "v2",

-await table.updateFieldMetadata([
-  { path: "clip_v2", metadata: { "lancedb:tag:archived": "true", "lancedb:tag:latest": null } },

-
-## Step 4: Confirm
-
-Report back:
- Which columns were updated and what was written
- The new table version number (from the result)
- Any columns skipped (e.g., already had up-to-date metadata)

-1. Read `table.schema` → all fields + existing metadata
-2. Generate a `lancedb:description` for each column based on name + type
-3. One `update_field_metadata` call with all descriptions
-4. Report

-**"Tag the columns in `model_outputs` with their field type and model"**
-1. Read the schema
-2. For each field, classify by name + Arrow type → set `lancedb:tag:field_type` and `lancedb:tag:model` where applicable
-3. Write in one batched call
-4. Report
-
-**"Group the feature columns in `training_features` into logical families and mark the latest version"**
-1. Read the schema
-2. Find version patterns → assign `lancedb:logical-column` and `lancedb:tag:version`; mark newest with `lancedb:tag:latest: "true"`
-3. Write in one batched call
-4. Show the grouping

-## Connect
-
-If you're connecting to a remote database, use this:
-```python
-import lancedb
-
-db = lancedb.connect("db://my-db", api_key=api_key, host_override=host_override) # remote
-```
-(values may be found in LANCEDB_API_KEY and LANCEDB_HOST_OVERRIDE, either in env vars or a .env file)
-
-If you're connecting to a local table using OSS LanceDB, use this:
-```python
-db = lancedb.connect("./camelot-db") # local/OSS
-```
-If you're not sure which, or if you can't find the api_key or host_override params, ask the user.
-
-**Place the local database directory next to the script/entrypoint that opens it** (i.e. resolve the path relative to the script, `Path(__file__).parent / "camelot-db"`), not buried under a shared `data/` folder. The Lance dataset is the database, not a data file — keeping it beside its code makes ownership obvious and paths stable regardless of the working directory the script is launched from.
-
-**Do not name the directory `lancedb`** (e.g. `./lancedb`, `./data/lancedb`). It collides with the imported `lancedb` package name, which is confusing to read and easy to shadow in scripts. Give it a name derived from the repo or dataset with a clear prefix/suffix — for example `./<dataset>-db`, `./<repo>_lancedb`, or `./vectordb`.
-
-Async:
-
-```python
-db = await lancedb.connect_async("./camelot-db")

-## Table Reads
-
-| Task | Preferred API |
-| --- | --- |
-| Vector search | `table.search(query_vector).limit(k)` |
-| Full scan with filters/projection (sync) | `table.search().where(...).select(...).limit(...)` |
-| Full scan with filters/projection (async) | `table.query().where(...).select(...).limit(...)` |
-| Filter | `.where("col > 10")` |
-| Projection | `.select(["id", "text"])` |
-| Bound result count | `.limit(20)` |
-| Collect bounded result as Python objects (default, no extra deps) | `.to_list()` on query/search result |
-| Collect bounded result as Arrow (default, `pyarrow` always available) | `.to_arrow()` on query/search result |
-| Collect bounded result as pandas (only if project uses pandas) | `.to_pandas()` on query/search result |
-| Collect bounded result as Polars (only if project uses polars) | `.to_polars()` on query/search result |
-
-## Sync vs Async Scan API
-
-The plain-scan entry point differs between the sync and async clients. **Verified against `lancedb` 0.34.0** — re-check if the pinned version changes:
-
- **Sync** (`lancedb.connect(...)`): the table has **no `.query()` method**. Use `.search()` with no argument for a plain scan; it returns a query builder that supports `.where()`, `.select()`, `.limit()`, and the `.to_list()` / `.to_arrow()` / `.to_pandas()` / `.to_polars()` collectors.
-  ```python
-  rows = table.search().where("status = 'ready'").select(["id", "text"]).limit(20).to_list()
-  ```
- **Async** (`lancedb.connect_async(...)`): the table has **both** `.query()` and `.search()`. Use `.query()` for a plain scan.
-  ```python
-  rows = await async_table.query().where("status = 'ready'").select(["id", "text"]).limit(20).to_list()
-  ```
-
-Do not call `table.query()` on a sync table — it raises `AttributeError`.
-
-## Local vs Remote Table Methods
-
-| API | Local table | Remote table | Agent guidance |
-| --- | --- | --- | --- |
-| `table.search(...)` | Yes | Yes | Preferred read path (sync + async) |
-| `table.query()` | Async only | Async only | Sync scan path is `table.search()`; `.query()` is the async scan builder |
-| `table.to_pandas()` | Yes | No / unsafe for portability | Avoid in portable code |
-| `table.to_arrow()` | Yes | No / unsafe for portability | Avoid in portable code |
-| `table.to_polars()` | Yes | No / unsafe for portability | Avoid in portable code |
-| `table.to_lance()` | Yes | No | Local/OSS escape hatch only |
-
-## Indexes
-
-Use `create_index(...)` for vector indexes and modern index configs. Use scalar indexes for filtered or merge keys.
-
-Common calls:
-
-```python
-table.create_index("vector")
-table.create_scalar_index("status")
-table.create_fts_index("text")
-```
-
-Check source docs before specifying advanced index config names or parameters.
-
-## Filtering And Recall Knobs
-
-```python
-table.search(query_vector).where("status = 'ready'")  # pre-filter by default
-table.search(query_vector).where("status = 'ready'", prefilter=False)
-table.search(query_vector).limit(10).refine_factor(20)
-table.search(query_vector).limit(10).nprobes(50)
-```
-
-Use post-filtering only when fewer than `limit` results are acceptable.
-
-## Diagnostics
-
-```python
-print(table.search(query_vector).where("year > 2000").limit(10).analyze_plan())
-print(table.index_stats("vector_idx"))
-```
-
-Use these before changing indexes or search tuning.
-
-## Column (Field) Metadata
-
-```python
-schema = table.schema                       # sync property; async: await table.schema()
-meta = schema.field("category").metadata    # dict[bytes, bytes] — Arrow metadata is bytes-keyed
-res = table.update_field_metadata(          # varargs: one dict per field; works local + remote
-    {"path": "category", "metadata": {"lancedb:description": "...", "lancedb:tag:field_type": "label"}}
-)
-res.version  # new table version
-```
-
-Merges by default; a `None` value deletes that key; `"replace": True` swaps the whole map. Nested fields use dot-paths (`"a.b.c"`). `replace_field_metadata` is deprecated. See `references/column_metadata.md` for key conventions (`lancedb:description`, `lancedb:tag:<name>`, `lancedb:logical-column`) and the authoring workflow.
-
-## Branches
-
-```python
-table.branches.list()                          # non-main branches; {} = only main
-exp = table.branches.create("exp")             # fork off main -> handle scoped to the branch
-wip = table.branches.checkout("wip")           # existing branch -> scoped handle (version= pins read-only)
-wip = db.open_table("t", branch="wip")         # or open scoped directly
-table.branches.delete("stale")                 # removes only the branch pointer
-table.current_branch()                         # None = main
-```
-
-There is no global switch — scoping is per table handle: any read/write on a branch handle lands on that branch; the original handle keeps targeting main. See `references/branch_ops.md` for the model and isolation checks.
-
-## Maintenance
-
-```python
-table.optimize()
-```
-
-Call this after every successful local/OSS ingestion. It handles compaction, cleanup of old versions according to retention, and index optimization. Do not add this for LanceDB Enterprise/Cloud remote tables; Enterprise handles compaction and cleanup automatically from cluster configuration.

-# Python Patterns
-
-Use these patterns when writing Python code with `lancedb`.
-
-## Before Writing Code
-
-Choose the output type from what the project actually depends on. **Do not assume `pandas` or `polars` is installed** — they are heavy dependencies that many LanceDB projects do not use. `pyarrow`, by contrast, ships as a LanceDB dependency and is always available, so it is a safe default to lean on.
-
-Default output (after applying `select()` and `limit()`):
-
- **Python objects**: `.to_list()` — a list of dicts, no extra dependencies. Prefer this for scripts, examples, and agent-generated code unless there is a reason to do otherwise.
- **PyArrow**: `.to_arrow()` — a `pyarrow.Table`, when the surrounding code is Arrow-native or you need columnar/zero-copy handoff.
-
-Only reach for a DataFrame when the project *already* declares that dependency:
-
- Pandas projects (pandas in `pyproject.toml`/requirements): `.to_pandas()`.
- Polars projects (polars declared): `.to_polars()`.
-
-If unsure, check the dependency manifest or the imports in surrounding files. When in doubt, use `.to_list()` or `.to_arrow()`.
-
-## Schema Design and Validation
-
-Favor `LanceModel` and Pydantic validation for Python schemas. They keep field
-types readable, validate source records before a write, and map directly to a
-LanceDB schema. Use `Vector(dimension)` for fixed-size vectors:
-
-```python
-from lancedb.pydantic import LanceModel, Vector
-
-class Document(LanceModel):
-    id: int
-    text: str
-    vector: Vector(384, nullable=False)
-
-rows = [Document.model_validate(row) for row in source_rows]
-table = db.create_table("documents", schema=Document)
-table.add(rows)
-```
-
-Use PyArrow schemas instead when the pipeline is already Arrow-native, needs
-record-batch streaming, or has runtime schema requirements that would make a
-Pydantic model harder to understand. Declare Pydantic as a direct project
-dependency when application code imports it, even if LanceDB also depends on it.
-
-## Recommended Patterns
-
-### Bounded search or query
-
-Use this for application reads, examples, notebooks, and agent-generated scripts:
-
-```python
-results = (
-    table.search(query_vector)
-    .where("status = 'ready'")
-    .select(["id", "text"])
-    .limit(20)
-    .to_list()  # or .to_arrow(); .to_pandas()/.to_polars() only if the project uses them
-)
-```
-
-Why: `search()` works across local and remote tables and on both the sync and async clients. `select()` avoids fetching unused columns. `limit()` prevents accidental full-table reads. `.to_list()` and `.to_arrow()` avoid assuming pandas/polars is installed (see "Before Writing Code").
-
-For a **plain scan** (no query vector), the entry point differs by client:
-
-```python
-# Sync client: no .query() method — use .search() with no argument.
-rows = table.search().where("status = 'ready'").select(["id", "text"]).limit(20).to_list()
-
-# Async client: use .query().
-rows = await async_table.query().where("status = 'ready'").select(["id", "text"]).limit(20).to_list()
-```
-
-`table.query()` on a sync table raises `AttributeError` (verified on `lancedb` 0.34.0). See the "Sync vs Async Scan API" section in `api_reference.md`.
-
-### Bounded query result conversion
-
-It is fine to collect bounded query/search results:
-
-```python
-arrow_table = table.search().select(["id"]).limit(100).to_arrow()  # sync plain scan
-rows = table.search(query_vector).limit(10).to_list()
-df = table.search(query_vector).limit(10).to_pandas()  # only if pandas is a project dep
-```
-
-### Local-only Lance dataset API
-
-`table.to_lance()` does not itself materialize the full dataset. It returns the underlying `lance.LanceDataset`, making the table accessible through the PyLance dataset API. Use it when the task is explicitly local/OSS and needs Lance dataset methods not exposed by LanceDB:
-
-```python
-# Local/OSS only: RemoteTable does not expose table.to_lance().
-ds = table.to_lance()
-for batch in ds.to_batches(columns=["id", "text"], batch_size=10_000):
-    process(batch)
-```
-
-### Async Python
-
-Keep the same shape and bound the result before collecting:
-
-```python
-results = await (
-    async_table.query()
-    .where("status = 'ready'")
-    .select(["id", "text"])
-    .limit(20)
-    .to_list()  # or .to_arrow()
-)
-```
-
-## Anti-Patterns
-
-**Avoid the following anti-patterns in your code.**
-
-### Table-level full materialization
-
-Avoid whole-table collectors in portable or large-table code:
-
-```python
-df = table.to_pandas()
-arrow_table = table.to_arrow()
-polars_df = table.to_polars()
-```
-
-Why: local tables expose these whole-table collectors, but remote tables intentionally do not — a remote production table can be far larger than a local development table, so it is easy to accidentally pull the entire table into memory.
-
-`table.to_lance()` is different: it is not a full materialization call, but it is still local/OSS-only and should not appear in code meant to run against remote Enterprise tables.
-
-### Unbounded result collection
-
-Avoid query/search collection without a meaningful limit:
-
-```python
-rows = table.search().to_list()               # unbounded plain scan
-rows = table.search(query_vector).to_list()   # unbounded vector search
-```
-
-Prefer `select(...).limit(...)` before collecting; for large reads, stream in batches instead.
-
-### Per-row writes
-
-Avoid loops that write one row per call:
-
-```python
-for row in rows:
-    table.add([row])  # one commit + fragment per row
-```
-
-Each `add()` creates a new version and fragment. Pass the whole batch in a single call, or chunk very large inputs:
-
-```python
-table.add(rows)  # single commit
-# for very large inputs, add batches of several thousand rows
-```
-
-After the final successful write to an embedded OSS table, call
-`table.optimize()`. Skip this for Enterprise/Cloud tables because their
-maintenance is automatic.
-
-### Drop-then-reuse the same table name (Enterprise/Cloud)
-
-Avoid dropping or overwriting a remote table and then reusing that name right away:
-
-```python
-db.drop_table("my_table")
-table = db.create_table("my_table", data=rows)          # reads 500 for ~5 min
-table = db.create_table("my_table", data=rows, mode="overwrite")  # same problem
-```
-
-Why: Enterprise/Cloud splits DDL (control plane) from query serving (data plane). The data plane caches the dataset behind a table name for up to `table_cache_ttl` (default 300s / 5 min), so after a drop/overwrite the DDL succeeds but queries against the reused name return `500 Internal Server Error` until the cache expires — and a fresh `describe` may still show the old schema. Instead, write to a **fresh name**, use `list_tables()` and fail if it already exists, then `rename_table(fresh, final)` onto the final name only after the old table's drop has propagated (~5 min). See the "Enterprise: never drop-then-reuse the same table name" section in `SKILL.md`. Local/OSS tables have no separate data plane — overwrite freely there.

-Avoid changing `nprobes`, `refine_factor`, or index types before checking the query plan and index stats. Diagnose first, then tune one knob at a time.

-# Python Performance Guidance
-
-Use this when writing Python code that ingests data, queries large tables, builds indexes, or investigates latency.
-
-## Ingestion
-
-### Recommended: validate schemas and records with Pydantic
-
-Favor `LanceModel` for readable Python schema definitions and validate source
-records before writing. Use PyArrow directly for Arrow-native or streaming
-pipelines where it is the clearer representation.
-
-```python
-from lancedb.pydantic import LanceModel, Vector
-
-class Document(LanceModel):
-    id: int
-    text: str
-    vector: Vector(384, nullable=False)
-
-rows = [Document.model_validate(row) for row in source_rows]
-table = db.create_table("documents", schema=Document)
-table.add(rows)
-```
-
-### Recommended: bulk ingestion for materialized data
-
-```python
-table.add(arrow_table)
-table.add(df)
-table.add(pa.dataset("data/", format="parquet"))
-```
-
-For very large initial loads, create the table empty first, then call `add(...)`. Passing data directly to `create_table(name, data)` can skip the auto-parallel write path.
-
-### Recommended: iterator ingestion for generated or streamed data
-
-```python
-def batches():
-    for raw in source:
-        vectors = model.encode(raw["text"])
-        yield pa.RecordBatch.from_pydict({**raw, "vector": vectors})
-
-table.add(batches())
-```
-
-Use chunks of several thousand rows or more when practical. Tiny batches and per-row writes create many small fragments.
-
-### Anti-pattern: per-row `add()`
-
-```python
-for row in rows:
-    table.add([row])
-```
-
-Each call creates a version and fragment. This slows ingestion and later queries.
-
-## Indexing
-
- Build a vector index once brute-force vector search becomes too slow. As a rule of thumb, local brute force is fine below roughly 100K vectors; beyond that, build an index.
- Use `IVF_PQ` as the general-purpose default. Enterprise builds this automatically.
- Use scalar indexes for filtered columns and merge/upsert keys.
- Use `BTREE` for mostly distinct numeric/string/temporal columns, `BITMAP` for booleans and low-cardinality columns, and `LABEL_LIST` for list membership queries.
- Keep full-text defaults unless phrase queries require position data.
-
-## Querying
-
-Always be explicit:
-
-```python
-table.search(query_vector).select(["id", "title"]).limit(20)
-```
-
- `select()` reduces bytes read and transferred.
- `limit()` prevents accidental full-table materialization.
- Pre-filtering is the default and guarantees returned rows satisfy the predicate.
- Use post-filtering only when fewer than `limit` results are acceptable.
-
-## Recall Tuning
-
-Tune one knob at a time:
-
- Quantized indexes: raise `refine_factor` to rescore more candidates on full vectors.
- HNSW-backed indexes: raise `ef`; start around `1.5 * k`, increase toward `10 * k` if recall is short.
- IVF candidate breadth: `nprobes` is auto-tuned; override only when a selective pre-filter leaves too few neighbors.
-
-## Maintenance
-
-After every successful embedded OSS/local ingestion, call `table.optimize()`.
-Do not add this to LanceDB Enterprise/Cloud remote table code; remote compaction
-and cleanup are handled automatically based on the Enterprise cluster
-configuration.
-
-Why local maintenance is needed:
-
- Frequent writes can create many small fragments. Queries then need to scan across more files, which can increase latency.
- Updates, deletes, and appends create new table versions. Old versions are retained for time travel and rollback, which can grow disk usage.
- Indexes may have newly added rows that are not yet fully optimized into the index structure.
-
-For local/OSS tables, run `optimize()` after the final successful ingestion
-write. Also run it after later batches of update/delete operations or on a
-regular maintenance schedule:
-
-```python
-table.optimize()
-```
-
-If the user wants more aggressive local disk cleanup, pass a shorter cleanup retention window:
-
-```python
-from datetime import timedelta
-
-table.optimize(cleanup_older_than=timedelta(days=1))
-```
-
-Do not use very short cleanup windows when the application depends on time travel, rollback, or old versions.
-
-## Diagnostics
-
-Before changing code or indexes, inspect:
-
-```python
-print(table.search(query_vector).where("year > 2000").limit(10).analyze_plan())
-print(table.index_stats("vector_idx"))
-```
-
-Look for high scan bytes, missing indexes, fragmented data, and unindexed rows.
-
-## Python Multiprocessing
-
-When using multiprocessing, use `spawn` rather than `fork`. LanceDB is multi-threaded internally, and `fork` plus a multi-threaded process is unsafe.

-# Connecting to a LanceDB remote server
-
-LanceDB Enterprise/Cloud deployments are served by a server implementing the
-lance-namespace OpenAPI spec
-(<https://github.com/lance-format/lance-namespace/blob/main/docs/src/spec.yaml>).
-Every remote (`db://...`) connection talks to such a server, and some operations
-exist only there. In particular, all operations around jobs (listing, inspecting,
-creating, or canceling jobs) run server-side — there is no local/OSS equivalent, so
-resolve a server connection before attempting any job work. The job REST methods
-themselves are documented in `references/remote_jobs.md`.
-
-Every request needs two things:
-
-1. **Base URL** — the server endpoint
-2. **Credentials** — an API key (`x-api-key` header over REST), and usually a database name (`x-lancedb-database` header)
-
-## Resolution steps
-
-1. If the user already gave a URL and API key (or said which environment they're working against), use that.
-2. Otherwise, look for credentials already available in the environment:
-   - Env vars like `LANCEDB_URI` / `LANCEDB_HOST` / `LANCEDB_API_KEY`
-   - A server endpoint already running or port-forwarded locally (the REST default port is 2333, i.e. `http://localhost:2333`)
-3. If you didn't find both pieces, ask the user directly: **"What's your LanceDB endpoint's URL, and what's your API key?"** Also ask which database to use if it isn't obvious. Don't guess or probe further — the user knows their deployment.
-
-## Validating the connection
-
-Make a cheap authenticated request and check the status before starting real work:
-
-```bash
-curl -s -w "\n%{http_code}" "{base_url}/v1/table/?limit=1" \
-  -H "x-api-key: <key>" \
-  -H "x-lancedb-database: <database>"
-```
-
- `200` — connection, key, and database header all good
- `401` — API key missing or wrong
- `400` mentioning a database header — this deployment expects `x-lancedb-database`
-
-## Non-REST equivalents
-
-The same credentials work through the SDKs and CLI:
-
- Python SDK: `lancedb.connect("db://<database>", api_key="<key>", host_override="<base_url>")`
- TypeScript SDK: `await lancedb.connect("db://<database>", { apiKey: "<key>", hostOverride: "<base_url>" })`
- `lancedb` CLI: a `[profiles.<name>]` entry in `~/.lancedb/config.toml` with `http_server_url`, `api_key`, `database`

-# Job operations over the LanceDB remote server REST API
-
-Jobs are server-side background operations on LanceDB Enterprise/Cloud — index builds,
-column backfills, materialized view refreshes, and similar async work. Endpoints that
-trigger async work (e.g. the column backfill or materialized view refresh endpoints)
-return a `job_id`; these four methods are how you track and manage those jobs.
-
-Resolve the connection first — see `references/remote_connect.md`. All four methods
-are **POST** requests under `{base_url}/v1/jobs/` with JSON bodies, and take the usual
-`x-api-key` / `x-lancedb-database` headers. If every job call returns `501`, job APIs
-are disabled on that deployment (the server has no job registry configured) — report
-that rather than retrying.
-
-## 1. List jobs — `POST /v1/jobs/list`
-
-The body is optional; an empty body lists everything. All fields are filters:
-
-```json
-{
-  "limit": 100,
-  "table_name": "my_table",
-  "job_type": "...",
-  "job_subtype": "...",
-  "state": "...",
-  "page_token": "..."
-}
-```
-
-```bash
-curl -s -X POST "{base_url}/v1/jobs/list" \
-  -H "x-api-key: <key>" -H "x-lancedb-database: <database>" \
-  -H "content-type: application/json" \
-  -d '{"table_name": "my_table"}'
-```
-
-Response:
-
-```json
-{
-  "jobs": [
-    {
-      "job_id": "...",
-      "table": "my_table",
-      "job_type": "...",
-      "job_subtype": "...",
-      "state": "done",
-      "created_at_millis": 1720000000000
-    }
-  ],
-  "page_token": "..."
-}
-```
-
-A `page_token` in the response means there are more results — pass it back in the next
-request to continue. Note list rows use a lowercase `state` string, while describe uses
-an uppercase `job_state`.
-
-## 2. Describe a job — `POST /v1/jobs/describe`
-
-Body: `{"job_id": "<id>"}`. Returns full detail for one job:
-
-```json
-{
-  "job_id": "...",
-  "job_type": "...",
-  "job_subtype": "...",
-  "job_state": "IN_PROGRESS",
-  "creation_ms": 1720000000000,
-  "spec": {},
-  "status": {}
-}
-```
-
-`job_state` is one of `IN_PROGRESS`, `CANCELLED`, `FAILED`, `DONE`. `spec` and `status`
-are job-type-specific JSON objects (the job's input specification and its current
-progress/status). Returns `404` for an unknown job id.
-
-## 3. Cancel a job — `POST /v1/jobs/cancel`
-
-Body: `{"job_id": "<id>"}`; response echoes `{"job_id": "<id>"}`. Cancellation is a
-service-level operation requiring the same administrative authorization as the
-`/admin` routes — a database-scoped API key that can list and describe jobs may still
-get a permission error here. Other errors: `404` unknown job, `409` state conflict
-(e.g. already in a terminal state), `429` too much write contention (safe to retry).
-
-## 4. Query job event history — `POST /v1/jobs/query_events`
-
-Returns the event history (state transitions, progress updates) for one or more jobs.
-Body: `{"job_id": "<id>"}` for one job, or `{"job_ids": ["<id>", ...]}` for a batch.
-Optional fields: `limit` (max event rows), `limit_per_job` (per job in a batch query),
-and `filter` — a SQL-like expression over the columns `state`, `updated_by`,
-`owner_component`, and `claim_entity`. (`full_text_search` is reserved and currently
-rejected as not implemented.)
-
-The response is **not JSON** — it is an Arrow IPC stream
-(`content-type: application/vnd.apache.arrow.stream`). Decode it, e.g. in Python:
-
-```python
-import pyarrow.ipc
-import requests
-
-resp = requests.post(
-    f"{base_url}/v1/jobs/query_events",
-    headers={"x-api-key": key, "x-lancedb-database": database},
-    json={"job_id": job_id},
-)
-resp.raise_for_status()
-events = pyarrow.ipc.open_stream(resp.content).read_all()
-```

-## Feature engineering (Geneva) jobs
-
-Feature engineering jobs — UDF column backfills and materialized view refreshes run
-through Geneva — are tracked **separately** from the `/v1/jobs` registry above. Their
-records live in a `geneva_jobs` table inside the database itself (in the `__system`
-namespace), and you access them through a Python `geneva` connection rather than the
-REST endpoints above:
-
-```python
-import geneva
-from geneva.jobs import JobStateManager
-
-# Same credentials as lancedb.connect / the REST API
-conn = geneva.connect("db://<database>", api_key="<key>", host_override="<base_url>")
-jsm = JobStateManager(conn)
-
-# List jobs. NOTE: status defaults to "RUNNING"; pass status=None for all jobs.
-# Statuses: PENDING | RUNNING | DONE | FAILED | CANCELLED
-jobs = jsm.list_jobs(table_name="my_table", status=None)
-
-# Fetch one job by id (returns a list of JobRecord)
-records = jsm.get("<job_id>")
-```
-
-Each `JobRecord` has `table_name`, `column_name`, `job_id`, `job_type`, `status`,
-`launched_at`, `completed_at`, `config`, `launched_by`, `manifest_id`, `cluster_name`,
-`metrics` (progress counters), `events` (human-readable history), and `updated_at`.
-For filters `list_jobs` doesn't support (e.g. time ranges), query the underlying table
-directly: `jsm.get_table(True).search().where("launched_at >= TIMESTAMP '...'")` —
-pass `True` to check out the latest version, since other processes update job state.
-
-Stale-status caveat: nothing reaps dead Geneva jobs, so a job can sit in
-`RUNNING`/`PENDING` forever if its worker died. Treat a job as effectively `FAILED`
-when it has been running longer than ~36 hours, or its `updated_at` is more than ~2
-hours old (this matches the heuristic the Geneva console UI applies on read).
-
-## Workflow tips
-
- To wait for async work (a backfill, an index build), poll `describe` until
-  `job_state` leaves `IN_PROGRESS`; on `FAILED`, pull `status` and `query_events` for
-  the failure detail.

-## Connect
-
-```typescript
-import * as lancedb from "@lancedb/lancedb";
-
-const db = await lancedb.connect("./camelot-db");
-```
-
-**Place the local database directory next to the script/entrypoint that opens it** (resolve the path relative to the module, e.g. via `import.meta.dirname` / `__dirname`), not buried under a shared `data/` folder. The Lance dataset is the database, not a data file — keeping it beside its code makes ownership obvious and paths stable regardless of the working directory the script is launched from.
-
-**Do not name the directory `lancedb`** (e.g. `./lancedb`, `./data/lancedb`). It collides with the imported `lancedb` package/namespace, which is confusing to read. Give it a name derived from the repo or dataset with a clear prefix/suffix — for example `./<dataset>-db`, `./<repo>_lancedb`, or `./vectordb`.
-
-Remote connections use `db://...` plus Enterprise/Cloud credentials and deployment settings. Check current source/docs for exact connection options.

-await table.search(queryVector).limit(10).ef(100).toArray();

-```
-
-Use `postfilter()` only when fewer than `limit` results are acceptable.
-
-## Diagnostics
-
-```typescript
-console.log(await table.search(queryVector).where("year > 2000").limit(10).analyzePlan());
-console.log(await table.indexStats("vector_idx"));
-```
-
-Use these before changing indexes or search tuning.
-
-## Column (Field) Metadata
-
-```typescript
-const schema = await table.schema();
-const meta = schema.fields.find((f) => f.name === "category")?.metadata; // Map<string, string>
-const res = await table.updateFieldMetadata([
-  { path: "category", metadata: { "lancedb:description": "...", "lancedb:tag:field_type": "label" } },
-]);
-res.version; // new table version
-```
-
-Merges by default; a `null` value deletes that key; `replace: true` swaps the whole map. Nested fields use dot-paths (`"a.b.c"`). See `references/column_metadata.md` for key conventions (`lancedb:description`, `lancedb:tag:<name>`, `lancedb:logical-column`) and the authoring workflow.
-
-## Branches
-
-```typescript
-const branches = await table.branches();       // async manager
-await branches.list();                         // non-main branches; {} = only main
-const exp = await branches.create("exp");      // fork off main -> Table scoped to the branch
-const wip = await branches.checkout("wip");    // existing branch -> scoped Table (version arg pins read-only)
-const wip2 = await db.openTable("t", { branch: "wip" }); // or open scoped directly
-await branches.delete("stale");                // removes only the branch pointer
-table.currentBranch();                         // null = main
-```
-
-There is no global switch — scoping is per table handle: any read/write on a branch handle lands on that branch; the original handle keeps targeting main. See `references/branch_ops.md` for the model and isolation checks.
-
-## Maintenance
-
-```typescript
-await table.optimize();
-```
-
-Call this after every successful local/OSS ingestion. It handles compaction, cleanup of old versions according to retention, and index optimization. Do not add this for LanceDB Enterprise/Cloud remote tables; Enterprise handles compaction and cleanup automatically from cluster configuration.

-# TypeScript Patterns
-
-Use these patterns when writing TypeScript code with `@lancedb/lancedb`.
-
-## Recommended Patterns
-
-### Bounded query
-
-Use this for application reads, scripts, and examples:
-
-```typescript
-const rows = await table
-  .query()
-  .where("status = 'ready'")
-  .select(["id", "text"])
-  .limit(20)
-  .toArray();
-```
-
-### Bounded vector search
-
-```typescript
-const rows = await table
-  .search(queryVector)
-  .select(["id", "text"])
-  .limit(20)
-  .toArray();
-```
-
-### Batch streaming for larger reads
-
-When the task needs many rows, avoid collecting everything at once:
-
-```typescript
-for await (const batch of table
-  .query()
-  .where("status = 'ready'")
-  .select(["id", "text"])
-  .limit(10_000)) {
-  process(batch);
-}
-```
-
-## Anti-Patterns
-
-**Avoid the following anti-patterns in your code.**
-
-### Table-level full materialization
-
-Avoid whole-table collectors in portable or large-table code:
-
-```typescript
-const tableArrow = await table.toArrow();
-```
-
-Why: local tables expose these whole-table collectors, but remote tables intentionally do not — a remote production table can be far larger than a local development table, so it is easy to accidentally pull the entire table into memory.
-
-### Unbounded result collection
-
-Avoid query/search collection without a meaningful limit:
-
-```typescript
-const rows = await table.query().toArray();              // unbounded plain scan
-const rows = await table.search(queryVector).toArray();  // unbounded vector search
-```
-
-Prefer `select(...).limit(...)` before collecting; for large reads, stream in batches instead.
-
-### Per-row writes
-
-Avoid loops that write one row per call:
-
-```typescript
-for (const row of rows) {
-  await table.add([row]); // one commit + fragment per row
-}
-```
-
-Each `add()` creates a new version and fragment. Pass the whole batch in a single call, or chunk very large inputs:
-
-```typescript
-await table.add(rows); // single commit
-// for very large inputs, add in chunks of several thousand rows
-```
-
-### Drop-then-reuse the same table name (Enterprise/Cloud)
-
-Avoid dropping or overwriting a remote table and then reusing that name right away:
-
-```typescript
-await db.dropTable("my_table");
-const table = await db.createTable("my_table", rows);                    // reads 500 for ~5 min
-const table = await db.createTable("my_table", rows, { mode: "overwrite" }); // same problem
-```
-
-Why: Enterprise/Cloud splits DDL (control plane) from query serving (data plane). The data plane caches the dataset behind a table name for up to `table_cache_ttl` (default 300s / 5 min), so after a drop/overwrite the DDL succeeds but queries against the reused name return `500 Internal Server Error` until the cache expires — and a fresh `describe` may still show the old schema. Instead, write to a **fresh name**, use `tableNames()` and fail if it already exists, then `renameTable(fresh, final)` onto the final name only after the old table's drop has propagated (~5 min). See the "Enterprise: never drop-then-reuse the same table name" section in `SKILL.md`. Local/OSS tables have no separate data plane — overwrite freely there.
-
-### Guessing performance fixes
-
-Avoid changing `nprobes`, `refineFactor`, `ef`, or index settings before checking `analyzePlan()` and `indexStats(...)`. Diagnose first, then tune one knob at a time.
@@ -1,78 +0,0 @@
-# TypeScript Performance Guidance
-
-Use this when writing TypeScript code that ingests data, queries large tables, builds indexes, or investigates latency.
-
-## Ingestion
-
- Prefer bulk or batched writes.
- Avoid per-row write loops; they create many small commits/fragments.
- For generated data, accumulate reasonable batches before adding.
- For file-backed data, prefer APIs that stream from Arrow/Parquet-style inputs when available.
-
-## Indexing
-
- Build a vector index once brute-force vector search becomes too slow. As a rule of thumb, local brute force is fine below roughly 100K vectors; beyond that, build an index.
- Use the general-purpose vector index defaults unless the task has explicit recall/latency requirements.
- Build scalar indexes for filtered columns and merge/upsert keys.
- Use full-text index phrase options only when phrase queries require them.
-
-## Querying
-
-Always be explicit:
-
-```typescript
-await table.search(queryVector).select(["id", "title"]).limit(20).toArray();
-```
-
- `select()` reduces bytes read and transferred.
- `limit()` prevents accidental full-table collection.
- Pre-filtering is the default behavior. Use `postfilter()` only when fewer than `limit` results are acceptable.
-
-## Recall Tuning
-
-Tune one knob at a time:
-
- Quantized indexes: raise `refineFactor(...)` to rescore more candidates on full vectors.
- HNSW-backed indexes: raise `ef(...)`; start around `1.5 * k`, increase toward `10 * k` if recall is short.
- IVF candidate breadth: `nprobes(...)` is usually auto-tuned; override only when a selective pre-filter leaves too few neighbors.
-
-## Maintenance
-
-After every successful embedded OSS/local ingestion, call `table.optimize()`.
-Do not add this to LanceDB Enterprise/Cloud remote table code; remote compaction
-and cleanup are handled automatically based on the Enterprise cluster
-configuration.
-
-Why local maintenance is needed:
-
- Frequent writes can create many small fragments. Queries then need to scan across more files, which can increase latency.
- Updates, deletes, and appends create new table versions. Old versions are retained for time travel and rollback, which can grow disk usage.
- Indexes may have newly added rows that are not yet fully optimized into the index structure.
-
-For local/OSS tables, run `optimize()` after the final successful ingestion
-write. Also run it after later batches of update/delete operations or on a
-regular maintenance schedule:
-
-```typescript
-await table.optimize();
-```
-
-If the user wants more aggressive local disk cleanup, pass a shorter cleanup retention window:
-
-```typescript
-const olderThan = new Date(Date.now() - 24 * 60 * 60 * 1000);
-await table.optimize({ cleanupOlderThan: olderThan });
-```
-
-Do not use very short cleanup windows when the application depends on time travel, rollback, or old versions.
-
-## Diagnostics
-
-Before changing code or indexes, inspect:
-
-```typescript
-console.log(await table.search(queryVector).where("year > 2000").limit(10).analyzePlan());
-console.log(await table.indexStats("vector_idx"));
-```
-
-Look for high scan cost, missing indexes, fragmented data, and unindexed rows.

-
-The default `lancedb` wheel targets `x86-64-haswell` (AVX2 + FMA + F16C) for full performance on modern hardware. Pre-Haswell hosts — Intel Sandy Bridge / Ivy Bridge / Westmere; AMD Bulldozer / Piledriver / Steamroller — don't have AVX2 and crash with `Illegal instruction` at `import lancedb`.

-
-```bash
-pip install lancedb-compat
-```
-
-Same Python API (`import lancedb` works as usual). The compat wheel is compiled at the `x86-64-v2` baseline (Nehalem-class) and uses runtime SIMD dispatch in the embedded lance crate to pick the right kernel tier (scalar / AVX / AVX+FMA / AVX2+FMA / AVX-512) at load time, so it still goes fast on modern hardware while running cleanly on the pre-Haswell silicon. Use `lance.simd_info()` from Python to verify which tier was selected.
-
-`lancedb` and `lancedb-compat` install to the same `lancedb/` namespace and conflict at install time. Pick one. To switch, `pip uninstall lancedb` first, then `pip install lancedb-compat` (or vice-versa).
-
-If you need a custom baseline (or `lancedb-compat` isn't yet published for your platform), build from source with the override:
-
-```bash
-RUSTFLAGS="-C target-cpu=x86-64-v2" maturin build --release
-pip install ./target/wheels/lancedb-*.whl

 ### Preview Releases

 Stable releases are created about every 2 weeks. For the latest features and bug fixes, you can install the preview release. These releases receive the same level of testing as stable releases, but are not guaranteed to be available for more than 6 months after they are released. Once your application is stable, we recommend switching to stable releases.
