-# Class: Branches
-
-Branch manager for a [Table](Table.md).
-
-Unlike tags, `create` and `checkout` return a new [Table](Table.md) handle scoped
-to the branch; writes on it do not affect `main`.
-
-## Methods
-
-### checkout()
-
-```ts
-checkout(name, version?): Promise<Table>
-```
-
-Check out an existing branch and return a handle scoped to it.
-
-With `version` set, the returned handle is pinned to that version of the
-branch (a read-only, detached view); otherwise it tracks the branch's
-latest and stays writable.
-
-#### Parameters
-
-* **name**: `string`
-
-* **version?**: `number`
-
-#### Returns
-
-`Promise`&lt;[`Table`](Table.md)&gt;

-
-#### Parameters
-
-* **name**: `string`
-    Name of the new branch.
-
-* **fromRef?**: `string`
-    Source branch to fork from. Defaults to `main`.
-
-* **fromVersion?**: `number`
-    A specific version on `fromRef`. Defaults to latest.
-
-#### Returns
-
-`Promise`&lt;[`Table`](Table.md)&gt;

-### merge()
-
-```ts
-merge(fromBranch, dryRun): Promise<MergeBranchResult>
-```
-
-Merge a branch into main.
-
-Set `dryRun` to `true` to preview the merge. A rejected merge resolves
-with `status: "rejected"` instead of throwing.
-
-#### Parameters
-
-* **fromBranch**: `string`
-    Branch to merge from.

-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).

-## Script
-
-Run the scanner when reviewing or modifying an existing codebase:
-
-```bash
-python skills/lancedb/scripts/check_materialization.py path/to/file_or_dir
-```
-
-The script reports likely unsafe full-table materialization in Python and TypeScript. Treat results as review prompts, not automatic proof of a bug.
