> Currently, most BlockingQueues in cassandra are creating without any limits (execution stages) or with limits high enough to consume gigabytes of heap (PeriodicCommitLogExecutorService). I have observed many cases where a single unresponsive node can bring down entire cluster because others accumulate huge backlogs of operations.
> We need to make sure each queue is configurable through a yaml entry or a system property and defaults are chosen so that any given queue doesn't consume more than 100M of heap. I have successfully tested that adding these limits makes cluster resistant to heavy load or a bad node.
