Hello Folks,
Is it possible to findout detail of those 275 pending tasks compactionstats
command output is showing?
I’ve bumpedup concurrent_compactors to 25 though not all threads are
compacting, only 8 threads are being used so i’m wondering how can I utilize
all configured concurrent compactors when there are still pending tasks?
[cassandra@server]$ nodetool compactionstats -H
pending tasks: 275
