When running file compaction in production, please be aware that:
- Only files in a single checkpoint are compacted, that is, at least the same
number of files as the number of checkpoints is generated.
- The file before merging is invisible, so the visibility of the file may be:
checkpoint interval + compaction time.
+- If the compaction takes too long, it will backpressure the job and extend
the time period of checkpoint.
