Will Jones	5c3bd68e58	feat: upgrade Lance to 3.0.0-rc.3 (#3104 ) Co-authored-by: Jack Ye <yezhaoqin@gmail.com>	2026-03-09 12:55:20 -07:00
Weston Pace	4be85444f0	feat: infer js native arrays (#3119 ) When we create tables without using Arrow by parsing JS records we always infer to float64. Many times embeddings are not float64 and it would be nice to be able to use the native type without requiring users to pull in Arrow. We can utilize JS's builtin Float32Array to do this. This PR also adds support for UInt8/16/32 and Int8/16/32 arrays as well. Closes #3115	2026-03-09 10:13:59 -07:00
