## Background SeaTunnel currently exposes only a small set of generic metadata fields for CDC rows. In practice, multi-database and multi-collection jobs also need source-side identifiers such as schema name or collection name as first-class metadata. Without these fields, downstream routing, auditing, and lineage logic often has to parse table identifiers manually or rely on connector-specific assumptions. ## Proposed change Extend CDC metadata exposure so source-side identifiers can be surfaced explicitly, including schema/namespace/collection level information where the source supports it. ## Expected behavior - Relational CDC sources can expose schema-level identifiers. - MongoDB-style CDC sources can expose collection/namespace identifiers. - Metadata semantics are documented consistently across connectors. - Existing metadata behavior remains backward compatible. ## Acceptance criteria - New metadata keys are available for supported CDC sources. - The keys can be surfaced through the existing Metadata transform or equivalent metadata projection path. - English and Chinese docs are updated with connector coverage and examples. - Add focused tests for metadata extraction and transform exposure. ## Out of scope - Source event timestamp metadata if handled separately. - Route rule evaluation changes. - Soft-delete conversion. -- This is an automated message from the Apache Git Service.
