Jack Ye	7f52ec8c36	feat(python): support child namepsace operations and json serialization for LanceDBConnection (#3265 ) ## Summary Add connection serialization and child namespace support to `LanceDBConnection`. - `DBConnection.serialize()` / `lancedb.deserialize()` for connection reconstruction in remote workers - Cache `namespace_client()` in `LanceDBConnection` to avoid repeated DirectoryNamespace builds - `LanceDBConnection` transparently delegates child namespace operations (open_table, create_table, list_tables, drop_table, create_namespace, etc.) to `LanceNamespaceDBConnection` via `_namespace_conn()` - Root namespace operations still go through the original Rust path - Generic worker property override mechanism: any `namespace_client_properties` key prefixed with `_lancedb_worker_` has the prefix stripped and overrides the corresponding property when `deserialize(data, for_worker=True)` - `LanceNamespaceDBConnection` stores `namespace_client_impl`/`namespace_client_properties` for serialization roundtrip --------- Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-04-12 16:49:45 -07:00
