### Purpose Linked issue: close #2979 Fix a bug in the Paimon sorted PK reader when the primary key contains a timestamp field. The log side stores keys as projected primary-key rows, but `PaimonSortedRecordReader` adapted those rows with the full table `RowType` before passing them to the Paimon key comparator. For composite primary keys containing `TIMESTAMP`, this could make timestamp fields resolve against the wrong full-row position and fail with `Unsupported data type to get timestamp: STRING NOT NULL`. ### Brief change log - build the Fluss-to-Paimon comparator adapter with the primary-key `RowType` instead of the full table `RowType` - add a regression test covering a composite primary key that contains a timestamp field ### Tests - `./mvnw -pl fluss-lake/fluss-lake-paimon -Dtest=PaimonSortedRecordReaderTest test` ### API and Format No API or storage format changes. ### Documentation No documentation changes. -- This is an automated message from the Apache Git Service.
