Subject [jira] [Commented] (CASSANDRA-6572) Workload recording / playback
Date Wed, 30 Apr 2014 11:30:22 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-6572?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13985381#comment-13985381

Benedict commented on CASSANDRA-6572:
-------------------------------------

I wouldn't worry about the negligible amount of memory wasted storing the data - after all,
if there are no new messages to log it means the server isn't serving any requests. A shutdown
hook is probably easiest and sufficient, as a periodic flush would also miss any messages
logged between last flush and shutdown.

> "Write sample mode" gets us part way to testing new versions against a real world workload,
but we need an easy way to test the query side as well.
