You can read and write the value of the following MBean via
JMX:org.apache.cassandra.db:type=CompactionManager - CoreCompactorThreads
If you modify CoreCompactorThreads it will be effective immediatly, I mean
assuming you have some pending compactions, you will see N lines with nodetool
compactionstats where N=<New CoreCompactorThreads value>.

We have commented out "concurrent_compactors" in our Cassandra 2.1.13
We would like to review this setting, as some issues indicate that the default
configuration may affect read/write performance.
Where can we see the value set for concurrent_compactors in our setup? Is it
possible to update this configuration without a restart?
