Re: Missing non composite column

Ok. I did assume the same, here is what i have tried to fetch composite columns via thrift and CQL query as well! Not sure why thrift API is returning me column name as empty! (Tried with Cassandra 1.1.5) Here is the program:

Compound primary key: Insert after delete

Hi, Is it possible to reuse same compound primary key after delete? I guess it works fine for non composite keys. -Vivek

Re: replaced node keeps returning in gossip

Hi When I sent the mail I'd had the new node on for about an hour, the old node died about an hour before that. The weirdness in the log files stopped yesterday afternoon, about 4 or 5 hours after I replaced the node so it seems to have resolved itself. Seeing as there's no error to look at in

unexpected behaviour on seed nodes when using -Dcassandra.replace_token

Hi all I recently tried to replace a dead node using -Dcassandra.replace_token=token, which so far has been good to me. However on one of my nodes this option was ignored and the node simply picked a different token to live at and started up there. It was a foolish mistake on my part because it

Re: unexpected behaviour on seed nodes when using -Dcassandra.replace_token

Yes. That would be a good jira if it is not already listed. If node is a seed node autobootstrap and replicate_token settings should trigger a fatal non-start because your giving c* conflicting directions. Edward On Fri, Oct 19, 2012 at 8:49 AM, Thomas van Neerijnen t...@bossastudios.com wrote:

why does my Effective-Ownership and Load from ring give such different answers?

I had a two node cluster that I expanded to four nodes. I ran the token generation script and moved all the nodes so that when I run nodetool ring each node reports 25% Effective-Ownership. However, my load numbers map out to 39%, 30%, 15%, 17%. How can that be? Thanks.

Re: constant CMS GC using CPU time

ok, let me try asking the question a different way ... How does cassandra use memory and how can I plan how much is needed? I have a 1 GB memtable and 5 GB total heap and that's still not enough even though the number of concurrent connections and garbage generation rate is fairly low. If I

Re: unnecessary tombstone's transmission during repair process

Gus, we've found the cause. It was a problem in Cassandra, but it has been already fixed in cassandra 1.1.6. Commit with the problem: 2c69e2ea757be9492a095aa22b5d51234c4b4102 You can see it at https://issues.apache.org/jira/secure/attachment/12544204/CASSANDRA-4561-CS.patch Commit with the fix:

Re: Using Cassandra to store binary files?

Hello, Thank you all for your responses. Performance is not an issue at all as I described, so it shouldn't be problematic. At least this is our current understanding. We will try it and post back if something interesting comes up. Many thanks. Regards, Vasilis On Tue, Oct 16, 2012 at 7:34
