Subject [jira] [Commented] (CASSANDRA-5451) Add Paxos TTL setting
Date Fri, 03 May 2013 13:34:15 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-5451?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13648404#comment-13648404

Sylvain Lebresne commented on CASSANDRA-5451:
---------------------------------------------

Just for the record, the only thing is that there is uses cases where a gcgs of 0 is actually
a good idea (if you ttl everything in the CF typically). In that case, we'd end up never removing
paxos state, which would be inefficient. And of course if someone uses a very short but non
zero gcgs with the same reasoning it could be problematic.

Anyway, I'm fine not adding a new setting for now, but it would be worth at least mentioning
in the NEWS file that there is a new use for gcgs and people needs to be aware of it. And/or,
maybe we could set the paxos TTL to max(gcfs, 3 hours) or some other hard-coded but reasonable
minimum?
