List some data collected from the production enviroment after we lauch this feature. A direct way to evaluate the performance of a load balancing algorithm is to look at the indicators we are concerned about, specifically P99 write latency. What is more, we care about the standard deviation of journal disk write throughput , the range of journal disk write throughput, and the top 10 of journal disk write throughput . Let's take a look at the comparison of these indicators one by one (launched on 1.10): - P99 write latency  It can be seen that the P99 write latency has significantly decreased from a peak of more than ten to twenty seconds to less than one second. - the standard deviation of journal disk write throughput  The peak standard deviation of journal disk write throughput has decreased from 25MB/s to 21MB/s. - the range of journal disk write throughput  The peak write throughput range has decreased from 150MB/s to 130MB/s. - Journal disk write throughput top 10  There is also a significant decrease in the top 10 journal disk write throughput. Could you help to review this BP? @shoothzj @wenbingshen @eolivelli @dlg99 @jiazhai -- This is an automated message from the Apache Git Service.
