Zheng Hu created HBASE-21657: -------------------------------- Summary: PrivateCellUtil#estimatedSerializedSizeOf has been the bottleneck in 100% scan case. Key: HBASE-21657 URL: https://issues.apache.org/jira/browse/HBASE-21657 Project: HBase Issue Type: Bug Reporter: Zheng Hu Assignee: Zheng Hu Attachments: hbase20-ssd-100-scan-traces.svg
We are evaluating the performance of branch-2, and find that the throughput in SSD cluster is almost the same as HDD cluster. so I made a FlameGraph on RS, and found that the PrivateCellUtil#estimatedSerializedSizeOf cost about 29% cpu, Obviously, it has been the bottleneck in 100% scan case.
