@Tyler: We were already running most of our machines in 64bit JVM (Sun, not
the OpenJDK). Those also crashed.
@Holger: Good to hear that. I'll schedule an update for our Cassandra
cluster.
Thank you both for your time.

Hi,
You do not need to have 700 Go of data in RAM. Cassandra is able to store on
disks and query from there if data is not cached in memory. Caches are
maintained by C* by itself but you still have to some configuration.
Supposing you want to store around 800 Go and with a RF=3, you will need
My rough understanding of the ruby code is that it auto connects if necessary
when you make a request.
i.e. your get turns into a _multiget call here
https://github.com/twitter/cassandra/blob/master/lib/cassandra/protocol.rb#L52
and that result is in a client connection if necessary
Hi Dwight,
I can confirm that issue on my MBP under Mountain Lion.
Can you create a ticker at https://issues.apache.org/jira/browse/CASSANDRA and
include the platform you are running on.

Going through this page and it looks like indexes are stored locally
http://www.datastax.com/dev/blog/cassandra-with-solr-integration-details .
My question is what happens if one of the solr nodes crashes? Is the data
indexed again on those nodes?
Yes the data is indexed again

Yes will do - I had already made the suggested change - cluster is up
and running.
Thanks

It works for me on Sun's jvm. It appears to be similar to:

Have you tried upgrading IBM's java or using Sun's?

3 hours ago I finished the upgraded of our cluster. Currently it runs quite

Is it possible to use a custom Partitioner type (other than RP or BOP) ?
Say if my rowkeys are all Integers and I want all even keys to go to
node1 and odd keys to node2, is it feasible ? How would I go about ?
Thanks.
Yes, you need to implement the org.apache.cassandra.dht.IPartitioner interface,
there are a couple of abstract implementations you could base it on.

I'm not endorsing the idea of doing this, but as a hack to see if
Hi!
I have 3 nodes ring running on Amazon EC2.
About once a week I see in the logs compaction messages and around the same
time info messages about GC (see below) that I think means it is taking too
long and happening too often.
Does it mean I have to reduce my cache size?
Thanks,
Tamar

hi all, I'm a bit new to Cassandra and was wondering what are the basic steps
that we must follow to optimize the Cassandra for performance in general and
how to improve the performance for select * from X type of queries. Any help
would be much appreciated. Note that, we have huge data
