compaction occurring very frequently
Hi All,
We have a cluster (2.1.2) of 3 nodes , There is one table which contains
huge amount of data and having sstable count more than 1800 on all 3 nodes.
We have noticed that suddently compaction for that CF occurs very
frequently right after completion of previous compaction and also taking
long time in compacting.
Par New collection time and CMS collection time have also increased on
those node.
Please suggest what could be the problem.
Regards:
Rahul Bhardwaj

Hi,
2.1.x does have compaction issues. Upgrading to 2.1.6 should help you. You
can also search this mailing list for some recommendations for that
specific problem since it is a recurrent issue.
