Subject [jira] [Commented] (CASSANDRA-10172) Hint compaction isn't actually disabled
Date Sat, 12 Sep 2015 17:10:45 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-10172?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14742130#comment-14742130
] 

Aleksey Yeschenko commented on CASSANDRA-10172:
-----------------------------------------------

bq. Right – after hint delivery. But you can see in the log I attached that compaction kicks
off before any deliveries.

Before delivery. Because we switched it to before in CASSANDRA-6998 to deal with expired hints
accumulating.
