------------------------------
Summary: [Iceberg] Support deletion vectors for format-version 3
tables
Key: FLINK-39019
URL: https://issues.apache.org/jira/browse/FLINK-39019
Project: Flink
Issue Type: New Feature
Components: Flink CDC
Reporter: suhwan
*Summary*
Implement deletion vector support in Flink CDC Iceberg connector to leverage
format-version 3 performance benefits for CDC workloads.
*Content*
https://iceberg.apache.org/spec/#deletion-vectors
Iceberg format-version 3 introduces binary deletion vectors which replace
positional delete files with compact bitmaps stored in Puffin files
(Current implementation uses equality delete files via
`RowDataTaskWriterFactory`)
*Proposed Changes*
# Check `table.properties().get("format-version")`
## For v3 tables with id fields -> use deletion vector
## etc tables -> use equality delete files
