> Currently we default concurrent_compactors to the number of avaliable CPUs which means compactions can theoretically take over all threads and prevent reads and writes from happening.
> I'm currently seeing an extreme case of this that is caused by [6405|https://issues.apache.org/jira/browse/CASSANDRA-6405]. But, in general, this is a bad default. We should probably default concurrent_compactors to num_cpu to cores/2 or even cores/4.
