Hi IoTDBers

  How do I know if the compaction thread is stuck or if there are no compaction tasks? 

From the log file I can't find that information.

In v0.12,I can see the log as "2022-02-26 08:18:35,625 [pool-18-IoTDB-Compaction_Schedule-root.ip5.ip55-0-1] INFO  o.a.i.d.e.c.c.r.s.RewriteCompactionFileSelector:115 - No merge candidates are found"
