Subject [jira] [Updated] (CASSANDRA-12335) Super columns are broken after upgrading to 3.0
Date Wed, 03 Aug 2016 13:59:20 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-12335?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sylvain Lebresne updated CASSANDRA-12335:
-----------------------------------------
    Attachment: 0001-Force-super-column-families-to-be-compound.txt

I'll add that what's above is a bit of work, I'm out for 3 weeks at the end of this week,
and there is other tickets/reviews that needs my attention until then, so there is no change
I can have a full patch for this till then, and I'm gonna remove myself as assignee to make
that clear (I can still pick it up when back if no progress has been made).

With that said, the very first thing I mentioned, forcing {{compound}} on upgrade, is very
trivial, and it would prevent future upgrade to write bad things on disk, so I think we should
commit that ASAP and I'm attaching the trivial patch. As said above, it at least fixes the
thrift side of things for new upgrades.
