Subject [jira] [Resolved] (CASSANDRA-12045) Cassandra failure during write query at consistency LOCAL_QUORUM
Date Wed, 06 Jul 2016 10:05:11 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-12045?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sylvain Lebresne resolved CASSANDRA-12045.
------------------------------------------
    Resolution: Not A Problem

As the error says, the values you are trying to insert are too big (they can't fit in a single
commit log segment, which they have to). You can bump the {{commitlog_segment_size_in_mb}}
segment *on all nodes* if you wish, but I wouldn't necessarilly advise it as Cassandra isn't
optimized for storing large values. The fact you store your xml file in a text column suggests
to me that you're not compressing it, and given the size of your xml, I'd personally definitively
compress it (client side). Otherwise, the traditional way to deal with large values is to
manually chunk them.

Overall, there is no bug here and this is a user question, so I'm going to close this ticket
and please reach out on the user mailing list (see bottom of http://cassandra.apache.org/)
if you need more info/help.
