Thanks @yuxiqian for the feedback! I've polished the documentation to clarify the relationship between metadata columns and Transform expressions. **Changes made:** - Added a note section explaining that `database_name`, `schema_name`, and `table_name` are also available via Transform expressions (`__namespace_name__`, `__schema_name__`, `__table_name__`) - Clarified that `op_ts` is only available via `metadata.list` - Explained the trade-offs: using `metadata.list` allows passing values directly to downstream sinks without transform rules (simpler for basic use cases) - Updated the table descriptions to mention the Transform expression alternatives The metadata definitions remain unchanged as you suggested. Please review the updated documentation and let me know if any further adjustments are needed. -- This is an automated message from the Apache Git Service.
