------------------------------------
Summary: distributedLogReplay performance regression
Key: HBASE-8680
URL: https://issues.apache.org/jira/browse/HBASE-8680
Project: HBase
Issue Type: Bug
Components: MTTR
Reporter: Jeffrey Zhong
Assignee: Jeffrey Zhong
The JIRA is to check in changes to address performance issues found during my
performance testing as following:
1) When WALEdits belongs to a region which split/merged later incur extra
waitUntilRegionOnline RPC call
2) Using a single shared connection for replaying archives better performance.
Everytime creating a new connection, it incurs 4+ seconds to establish a
connection to ZK.
3) other small modifications to mitigate excessive logging
