The current implementation of RemoveDanglingDeletesSparkAction keeps equality delete files if their lower/upper bounds don't overlap with lower/upper bounds of data files with a lower sequence number. These delete files are dangling because they are always skipped during scans. When they add up, a scan can slow down. This PR collects all delete files from a full scan into a set and then removes all delete files that aren't in the set. This approach guarantees that all dangling delete files are deleted regardless of their type. -- This is an automated message from the Apache Git Service.
