<!-- 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>
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);
The quickstart contains more complete examples.
