If you are doing only writes and no reads, then 'cold_reads_to_omit' is
probably preventing your cluster from crossing a threshold where it decides
it needs to engage in compaction. Setting it to 0.0 should fix this, but
remember that you tuned it as you should be able to revert it to default
thre
I read the CQL table properties again.This property could contorl the
compaction . Right now My C* cluster only write without any read.

Reason for me was that those minor compactions did not get triggered
since there were almost no rea
No,to confirm this I have run the command all my nodes:bin/nodetool
enableautocompaction
