--------------------------------------------

CASSANDRA-9662 will probably resolve the pending compactions problem.

> After upgrading our cassandra staging cluster version from 2.1.6 to 2.1.7, the average load grows from 0.1-0.3 to 1.8.
> Latencies did increase as well.
> We see an increase of pending compactions, probably due to CASSANDRA-9592.
> This cluster has almost no workload (staging environment)
