> Benchmark the difference in performance between CASSANDRA-6504 and trunk.
> * Updating totally unrelated counters (different partitions)
> * Updating the same counters a lot (same cells in the same partition)
> * Different cells in the same few partitions (hot counter partition)
> benchmark: https://github.com/iamaleksey/cassandra/commits/6504
> compared to: https://github.com/iamaleksey/cassandra/commits/trunk
> So far, the above changes should only affect the write path.
