## Summary Prevent large JavaScript table-listing limits from wrapping during the native `u32` conversion. With two tables, `limit: 2 ** 32` currently returns no tables and `2 ** 32 + 1` returns only one. Validate nonnegative safe integers using the existing helper and clamp valid limits above `u32::MAX` before calling the native binding. Apply the same normalization to `tableNames` and `listTables`, including namespace overloads. Undefined, zero, small limits and `u32::MAX` keep their existing behavior. ## Validation Built the real Node native extension from main `0aa842b17f13d1f8ffd2851bc57c222bc5a376ba` with the repository's `pnpm build`, using locked dependencies and reusable build caches. No mocked/released native extension or disabled TypeScript diagnostics. With identical regression tests and that native library in fresh Jest processes: - Baseline: 40 passed, 8 failed; candidate: **48 passed**, no failures. - Both arms: `pnpm run tsc` and `pnpm run docs` passed. - Changed-file Biome check passed. Tests cover wrapping limits, invalid numbers, zero/small/u32 limits, defaults and both overload forms. Validation is the focused connection suite, not the complete repository suite. No performance claim. AI-assisted implementation and verification; the patch and exact tested source bytes were reviewed before publication.

The ultimate multimodal data platform for AI/ML applications.
LanceDB is designed for fast, scalable, and production-ready vector search. It is built on top of the Lance columnar format. You can store, index, and search over petabytes of multimodal data and vectors with ease. LanceDB is a central location where developers can build, train and analyze their AI workloads.
Demo: Multimodal Search by Keyword, Vector or with SQL
Star LanceDB to get updates!
