> [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
> Priority: Not a Priority
>
> *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
