> Porting per-CF set metrics for RPC times and response sizes from 0.89-fb to trunk. For each "mutation signature" (a set of column families involved in an RPC request) we increment several metrics, allowing to monitor access patterns.  We deal with guarding against an explosion of the number of metrics in HBASE-4638 (which might even be implemented as part of this JIRA).
