> 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
