In-process ClickHouse SQL engine for Python — run ClickHouse SQL queries directly on local files, remote databases, and cloud storage without a server. Use when the user wants to write SQL queries against Parquet/CSV/ JSON files, use ClickHouse table functions (mysql(), s3(), postgresql(), iceberg(), deltaLake() etc.), build stateful analytical pipelines with Session, use parametrized queries, window functions, or other advanced ClickHouse SQL features. Also use when the user explicitly mentions chdb.query(), ClickHouse SQL syntax, or wants cross-source SQL joins. Do NOT use for pandas-style DataFrame operations — use chdb-datastore instead.

Analyze A-share stocks using fixed scripts, supporting the maintenance of local watchlists and position pools, fetching individual stock and concept sector data, querying risks such as financial report disclosures and share reduction announcements, and outputting structured recommendations including Buy, Watch, Hold, Reduce Position, and Sell. Suitable for scenarios where you need to update local stock pools, fetch real-time data, compare the top three strongest stocks in a concept sector, or generate transaction analysis with risk prompts.
