Hello all,
We're running cassandra on EC2 (via Rightscale), and I'm working on
connecting up the cassandra JMX monitoring to try to debug why our 0.6.1
Cassandra machine spike to 100% CPU and then choke after about 6 hours worth
of production data running through them.
We're running on 64 bit EC2
We only have a few CFs (6 or 7). I've increased the MemtableThroughputInMB
and MemtableOperationsInMillions as per your suggestions. Do we really need
a swap file though? I suppose it can't hurt, but with my problem in
particular we weren't maxing out main memory.
We'll be running another test to

Hello Cassandra users+experts,
Hopefully someone will be able to point me in the correct direction. We have
cassandra 0.6.1 working on our test servers and we *thought* everything was
great and ready to move to production. We are currently running a ring of 4
large instance EC2 (http://aws.amazon.
