Hi there -- I was wondering if there was any roadmap items, design docs, or general thinking around support for Iceberg merge-on-read positional deletes in Flink. If I understand correctly Flink supports equality deletes only for Iceberg merge-on-read updates (whereas Spark supports positional deletes only). I'm trying to understand if that's just a feature gap in the current state for Flink or a more fundamental platform-level limitation. I'm investigating a solution for streaming ingestion into an Iceberg-based data lake, but have concerns about the read side performance for equality deletes

I don't think there's a lot of thinking done around this problem in the Flink community, but I would hope/think that the Iceberg community thinks about this and would flag/propose something for Flink itself. I haven't seen anyone raise this in the Flink community recently

Thanks for the info!
