column metadata and sstable

Dear all, I'm wondering what's the advantage of assigning column metadata when NOT using secondary indices. I've gone through the SSTable internal and found out it won't do such conversion.Thus I think the only advantage we got via column metadata is a data validation type, am I correct?

Re: Secondary indexes and drop column family

Answered my own question; a snapshot gets taken when you drop a CF, per: http://cassandra-user-incubator-apache-org.3065146.n2.nabble.com/Cassandra-take-a-snapshot-after-a-column-family-update-td6222772.html So, I can recover to a known-good working position, and delete my indices properly. T

Secondary indexes and drop column family

Hey all; So, I've managed to get myself into a position where I'm not sure how to recover. I have a column family that I was a significant number of secondary indexes on. Some buggy code created a bunch of useless indexes accidentally, and I took what (at the time) seemed the most obvious pa

Probably. 0.8.3 will be out shortly with a "real" fix. In the meantime, restarting the node(s) logging schema disagreement should work around the problem. On Fri, Aug 5, 2011 at 4:57 PM, myreasoner wrote: > I got a 5-node cluster running on 0.8.2.  From the system log I'm seeing the > exact pro

I got a 5-node cluster running on 0.8.2. From the system log I'm seeing the exact problem reported in https://issues.apache.org/jira/browse/CASSANDRA-2946. And any "create column family xyz" returns null. Is it related to CASSANDRA-2946? -- View this message in context: http://cassandra-user-i

That is something we have to update, thanks for mentioning that. We should just be depending on apache hadoop components now that we are no longer supporting hadoop output streaming. On Aug 5, 2011, at 10:27 AM, Dean Hiller wrote: > oh, cloudera repo is down like a previous poster just said...
