chdb 4.2.0
Requires chdb-core>=26.5.0.
New
chdb.agents.ChDBTool(beta/experimental) — the canonical Python agent tool for chDB, and the reference implementation of a cross-language contract (chdb/agents/CONTRACT.md). Query + introspection with engine-enforced read-only (readonly=2, keepsfile()/s3()/url()usable), server-side parameter binding, result caps with an explicittruncatedflag, error-to-model dispatch, optional query timeout,attach_file, an optional file allowlist, and a Python-onlydataframe_queryoverPython(). A shared conformance fixture keeps other-language bindings in lock-step. The API is beta and may change in a minor release — pin a version if you depend on it.- DataStore → ClickHouse writeback —
to_clickhousewrites an in-memory DataFrame to a ClickHouse server (same- and cross-server). - DataStore pandas 3.x —
pd.col()expressions; lazy metadata (.columns/.dtypes/.shape/.indexresolved without materializing). - DataStore ergonomics —
output_format="DataStore"dispatch and mirrored UDF surfaces from chdb-core.
