Description

Description

target file overlap with previous file 

 

Reason

In the process of getting the file list and starting to select files, the file list is updated (the file is deleted or the status is updated). When a seq file is occupied and deleted by other compaction thread, and it happens to select files in cross space compaction, the deleted file will be filtered out, resulting in an overlap target file.

 

Solution

Do not filter out any seq files before selecting the files. After selecting the files, judge whether the seq files have been deleted or being compacted. If there are any, the task will be discarded.
