Subject [jira] [Commented] (CASSANDRA-10579) IndexOutOfBoundsException during memtable flushing at startup (with offheap_objects)
Date Mon, 02 Nov 2015 14:07:27 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-10579?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14985256#comment-14985256
] 

Branimir Lambov commented on CASSANDRA-10579:
---------------------------------------------

I see, {{addNewKey}} calls it as well. I would remove the separate comment and change the
"handles..." one to include that it applies {{updateFunction}}.

> Sometimes we have problems at startup where memtable flushes with an index out of bounds
exception as seen below. Cassandra is then dead in the water until we track down the corresponding
commit log via the segment ID and remove it:
