Subject [jira] [Commented] (YARN-6768) Improve performance of yarn api record toString and fromString
Date Fri, 07 Jul 2017 16:25:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-6768?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16078331#comment-16078331

Nathan Roberts commented on YARN-6768:

Thanks Jon! As a datapoint, I have a testcase that measures how quickly we can handle NodeUpdateSchedulerEvents
when a user is at their user limit. This path causes the ActivitiesLogger to be invoked at
a very high rate. The most expensive operation within the ActivitiesLogger is application.getApplicationId().toString().
When I apply the patch on this jira, the throughput improves from 22K/sec to 32K/sec.
