I agree that caching equality deletes on the executor for the entire duration of a job (or longer) is the right long-term goal. However, with the current implementation, performance improves when delete file sets are identical, but degrades when they are only partially overlapping. Could you consider making this behavior opt-in? Similar but non-identical delete file sets are quite common in CDC scenarios, so having a configuration flag would help prevent potential regressions. -- This is an automated message from the Apache Git Service.
