Hi,
You can read and write the value of the following MBean via
JMX:org.apache.cassandra.db:type=CompactionManager - CoreCompactorThreads
- MaximumCompactorThreads
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>.
Best,
Romain

Hello,
We have commented out "concurrent_compactors" in our Cassandra 2.1.13
installation.
We would like to review this setting, as some issues indicate that the default
configuration may affect read/write performance.
https://issues.apache.org/jira/browse/CASSANDRA-8787
https://issues.apache.org/jira/browse/CASSANDRA-7139
Where can we see the value set for concurrent_compactors in our setup? Is it
possible to update this configuration without a restart?
Best Regards,
Julian.
