> This Jira explores the performance of different memstore compaction policies.
> It presents the result of write-only workload evaluation as well as read
> performance in read-write workloads.
> We investigate several settings of hardware (SSD, HDD), key distribution
> (Zipf, uniform), with multiple settings of the system, and compare measures
> like write throughput, read latency, write volume, total gc time, etc.
> The submitted patch sets some system properties at the values yielding
> optimal performance. In addition we suggest a new Adaptive memstore
> compaction policy that shows good tradeoffs between write throughput and
> write volume.
