> URL: https://issues.apache.org/jira/browse/HBASE-8680
> Project: HBase
> Issue Type: Bug

> Reporter: Jeffrey Zhong
> Assignee: Jeffrey Zhong
> Fix For: 0.98.0, 0.95.2

> Attachments: hbase-8680.patch

>
> 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
