Subject [jira] [Commented] (HBASE-12988) [Replication]Parallel apply edits on row-level
Date Sat, 06 Jun 2015 18:53:02 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12988?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14575879#comment-14575879

Lars Hofhansl commented on HBASE-12988:
---------------------------------------

Another observation from [~abhishek.chouhan]'s testing was that the majority of the time is
spent at the sink applying the edits. The test was done over high latency links (~60ms), and
this surprised me the most. It's not the network, it's the time spent on the sink and the
fact that the source is not doing _any_ work during that time, since it synchronously waits
for the sink to finish.
