Subject Re: Compacting manual managing and optimization

See the online help in cassandra-cli on CREATE / UPDATE COLUMN FAMILY for min_compaction_threshold
and max_compaction_threshold. 

Also look in the cassandra.yaml file for information on configuring compaction. 

If compaction is really hurting your system it may be a sign that you need to scale up or
make some other changes. What does your cluster look like ? # nodes, load per node, throughput,
# clients etc
