cuijianwei commented on HBASE-10129:
------------------------------------
[~eclark], I agree this feature should not affect hbase performance. I think we
might add a configuration option such as
'regionserver.rpc.latency.percentile.enable' to enable or disable this feature.
Then, users can decide whether enable this feature according to their needs. We
need to do some comparisons to efficiency change after enable this feature. Is
there any benchmark when doing efficiency comparisons?

> It is important for applications to get latency statistics when invoking
> hbase apis. Currently, the average latency of methods in HRegionInterface
> will be computed in HBaseRpcMetrics. However, user might expect more detail
> latency statistics, such as 75% percentile latency, 95% percentile latency,
> etc. Therefore, will it be useful if we computing latency percentiles for rpc
> invoking of region server methods?
