[jira] [Created] (CASSANDRA-12248) Allow tuning compaction thread count at runtime

Tom van der Woerdt created CASSANDRA-12248:
----------------------------------------------

             Summary: Allow tuning compaction thread count at runtime
                 Key: CASSANDRA-12248
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-12248
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Tom van der Woerdt
            Priority: Minor


While bootstrapping new nodes it can take a significant amount of time to catch up on compaction or 2i builds. In these cases it would be convenient to have a nodetool command that allows changing the number of concurrent compaction jobs to the amount of cores on the machine.

Alternatively, an even better variant of this would be to have a setting "bootstrap_max_concurrent_compactors" which overrides the normal setting during bootstrap only. Saves me from having to write a script that does it.
