ArnavBalyan opened a new pull request, #8990: URL: https://github.com/apache/paimon/pull/8990
### Purpose - Chain table does merge on read. Delete in the delta branch can remove the row from older branch. - However, compaction also sets the DV bit. In this scenario, the old and new copy have the same key, sequence field and number. - The merge comparator cannot handle tie. If delete is merged last, the row is wrongly deleted. - Factor in the delete/insert order in the comparator ### Tests - UT -- This is an automated message from the Apache Git Service.
