Hi,
I have a keyspace called Index.
I am trying to create it when I create a new cluster from the script that
was created on the old cluster.
create keyspace Index
with placement_strategy = 'SimpleStrategy'
and strategy_options = {replication_factor : 3
and durable_writes = true;

Hi All,
I'm trying to start up Cassandra 1.0.5 on a Cent OS 6 machine. I installed JNA
through yum and made a symbolic link to jna.jar in my Cassandra lib directory.
When I run bin/cassandra -f, I get the following:
INFO 09:14:31,552 Logging initialized
INFO 09:14:31,555 JVM
Was't that on the 1.0 branch ? I'm still running 0.8x ?
@Peter: investigating a little more before answering. Thanks

There was a recent patch that fixed an issue where counters were hitting
the same natural endpoint rather then being randomized
This is quite a different subject and the question has already been asked a
few days ago (December, 1) :

Anyways, you can test it by yourself changing the name of the column
family. I don't know more about it by myself.

Possible, but unlikely. See
https://issues.apache.org/jira/browse/CASSANDRA-3537 for an example of
a memory leak that wasn't.
I didnt get the point. I have slowly increasing memory load on node, no
flushable memtables. How it could not be memory leak? Also running
nodetool upgradesstables
Hi Sylvain,
Writes under the same row key are atomic (*even across column families*)
in the
sense that they are either all persisted or none are.
Is this new feature for 1.x, or it also applies to previous version of
Cassandra?

I'm running Cassandra 1.0.1 if that makes any difference.

I'm going to mix the response to your email along with my other email from

Sorry this is a little long, but I'm stomped and I'm trying to describe

We are currently testing cassandra in RHEL 6.1 64 bit environment

Hello,
When I use nodetool cfstas, I see read/write for both keyspace and column
family. I assume both number are counted across the ring, but I saw different
read/write counts showed on one node comparing to other 7 nodes.
node 1,2,4-8:
Keyspace: ks
Read Count: 44285565
Hi
Here is the case, if we have only two nodes, which share the data (write
one, read one),

How about the conflict data when the two node on line separately. How it
synchronized by two nodes when they both on line finally?
Briefly, it's based on timestamp conflict resolution. This may be a
good resource:

1) Are KS level counts and CF level counts for whole cluster or just for an
individual node?
Individual node.
Also note that the CF level counts will refer to local reads/writes
submitted to the node, while the statistics you get from StorageProxy
(in JMX) are for requests routed. In general,
