Add a central documentation link registry (`lancedb::docs::DocLink`) in the Rust core that builds `docs.lancedb.com` URLs with UTM parameters (`utm_source=lancedb_sdk`, `utm_medium=warning|error`, `utm_campaign=<id>`, `utm_content=<sdk>-<version>`) placed before any `#anchor` fragment and without user-identifying data. - Initialize `utm_content` per language binding (`python`, `nodejs`, `cli`, defaulting to `rust`) and expose the link builder to Python so `DBConnection` and `Job` stubs reuse the core definitions. - Append published documentation links to Enterprise-only `NotSupported` / `NotImplementedError` errors across database, job, catalog, and table operations. - Emit rate-limited maintenance warnings (once per table per process when `warn` logging is enabled) when opening a native table with at least 100 small fragments (`< 100k` physical rows each) or at least 1,000,000 unindexed rows on an optimizable user index, reading only manifest metadata without opening data or `_indices/` files, and document the thresholds in the compaction and reindexing guides. - Verify published/in-repo `docs/web/` targets and `#anchor` fragments in unit tests and include extracted SDK links in the scheduled `docs-link-check` workflow.

LanceDB JavaScript SDK
A JavaScript library for LanceDB.
Installation
npm install @lancedb/lancedb
This will download the appropriate native library for your platform. We currently support:
- Linux (x86_64 and aarch64 on glibc and musl)
- MacOS (Intel and ARM/M1/M2)
- Windows (x86_64 and aarch64)
Usage
Basic Example
import * as lancedb from "@lancedb/lancedb";
const db = await lancedb.connect("data/sample-lancedb");
const table = await db.createTable("my_table", [
{ id: 1, vector: [0.1, 1.0], item: "foo", price: 10.0 },
{ id: 2, vector: [3.9, 0.5], item: "bar", price: 20.0 },
]);
const results = await table.vectorSearch([0.1, 0.3]).limit(20).toArray();
console.log(results);
