Get warehouse metadata (databases, tables, and fields) for all databases visible to the current user. References between rows are emitted as raw numeric ids (db_id, table_id, parent_id, fk_target_field_id).

Sections must be opted into with the with-databases, with-tables, and with-fields query parameters — they all default to false. The response is streamed for efficiency with large schemas.

Requires View data → Can view and Create queries → Query builder only (or Query builder and native) permissions on each database and table.
