## Summary - Exposes `Session` in Python and Typescript so users can set the `index_cache_size_bytes` and `metadata_cache_size_bytes` * The `Session` is attached to the `Connection`, and thus shared across all tables in that connection. - Adds deprecation warnings for table-level cache configuration 🤖 Generated with [Claude Code](https://claude.ai/code) --------- Co-authored-by: Claude <noreply@anthropic.com>
