If its occurring that often you can monitor nodetool compactionstats to see

Thanks a lot Chris,
I had noticed that even the counter in the TotalCompactionsCompleted is
higher than the number of SSTables compactions, that is what interests me
most. I measured the number of compactions turning on the log_all in the
compaction settings in the tables and reading the
CompactionMetrics is a combination of the compaction executor (sstable
compactions, secondary index build, view building, relocate,
garbagecollect, cleanup, scrub etc) and validation executor (repairs). Keep
in mind not all jobs execute 1 task per operation, things that use the
Kurt,
I apreciate your answer but I don't believe CompletedTasks count the
"validation compactions". These are compactions that occur from repair
operations. I am running tests on 10 cluster nodes in the same physical
rack, with Cassandra Stress Tool and I didn't make any Repair commands. The
Dear community,
I am studying the behaviour of the Cassandra TimeWindowCompactionStragegy.
To do so I am watching some metrics. Two of these metrics are important:
Compaction.CompletedTasks, a gauge, and the TotalCompactionsCompleted, a
Meter.
According to the documentation (
