Hi,
maybe you are running into an issue that I also had on my test cluster.
Since there were almost no reads on it cassandra did not run any minor
compactions at all. Solution for me (in this case) was:
ALTER TABLE <tablename> WITH compaction = {'class':
'SizeTieredCompactionStrategy', 'min_threshold': '4', 'max_threshold':
'32', 'cold_reads_to_omit': 0.0};
where cold_reads_to_omit is the "trick".
Anyway as Eric and Marcus among others suggest, do not run 2.1.2 for
production as it has many issues. I'm looking forward to test 2.1.3 when
it arrives.
Cheers,
Roland
