cuijianwei updated HBASE-10129: ------------------------------- Attachment: HBASE-10129-0.94-v1.patch This patch will computing real time rpc invoke latency percentiles for methods of HRegionInterface, including: 1. Based on MetricsHistogram, implement MetricsTimeVaryingHistogram which will compute real time percentiles for metric; 2. Add 999th percentile statistics for MetricsHistogram; 3. Extend HBaseRpcMetrics to compute rpc invoke real time latency percentiles based on MetricsTimeVaryingHistogram. > support real time rpc invoke latency percentile statistics for methods of > HRegionInterface > ------------------------------------------------------------------------------------------- > > Key: HBASE-10129 > URL: https://issues.apache.org/jira/browse/HBASE-10129 > Project: HBase > Issue Type: Improvement > Components: regionserver > Affects Versions: 0.94.14 > Reporter: cuijianwei > Attachments: HBASE-10129-0.94-v1.patch > > > 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? -- This message was sent by Atlassian JIRA (v6.1.4#6159)
