Subject Re: Secondary index data gone after restart (1.1.1)
Date Wed, 27 Jun 2012 10:58:21 GMT
CASSANDRA-3954 disabled caches on secondary index CF's in 1.1.0 and  CASSANDRA-4197 enabled
it in 1.1.1

Can you create a ticket on https://issues.apache.org/jira/browse/CASSANDRA

I guessing this has something to do with the local partitioner used for the secondary index
Cf. That would explain the BigInteger value (from the RP) and the TimeUUIDType could come
from the LocalToken. 

Cheers

Is this a bug, should I file a bug report?
