Subject [jira] [Commented] (CASSANDRA-13031) Speed-up start-up sequence by avoiding un-needed flushes
Date Tue, 03 Jan 2017 16:55:58 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-13031?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15795513#comment-15795513
] 

Ariel Weisberg commented on CASSANDRA-13031:
--------------------------------------------

Are these logs apples to oranges? There are 40 instances in one and one in the other and the
code change doesn't look like it should remove some of them like changes to triggers or functions.

> Similar to CASSANDRA-12969, do a conditional update for all functions
>     with a forced blocking flush to avoid slowed-down boot sequences. The
>     small performance hit of doing a read is always smaller than the one
>     associated with a fsync().
