Scan query source schema
Scans the schema of one query source into the standard shape: tables with columns of . For the semantic layer, tables are explores and columns are field ids; for warehouse SQL, tables come from the warehouse catalog resolved for your credentials, like the SQL runner; the duckdb source has no schema of its own — its tables are the references given to each query.
Path Parameters
Discriminator for every query source a project can execute queries against. A query source is anything that can scan a schema and run a query returning the standard table format (ResultColumns + rows behind a queryUuid): the project warehouse, the semantic layer, the DuckDB compose engine, and — later — CSV uploads, HTTP APIs, Google Sheets, etc.
Deliberately NOT WarehouseTypes: sources are not warehouses, they plug in above the warehouse client layer.
