    Description

      After checkpoint abort, the files in cp5 may fall into cp6, because the compaction commit is deleted first and then added, which may lead to:
      -Delete a file
      -Add the same file again

      This causes the deleted file not to be found.

      We need to properly process the merge of the compression files.
