For anyone interested, the framework can now deploy and stress Cassandra on
multi EC2 regions.

I'm please to share a framework for running Cassandra stress tests on EC2.

The framework is a collection of Ansible playbooks and scripts, allowing to:
- Create a Cassandra cluster (setting server type, version, etc)
- Launch any
I'm running benchmark on a 2 nodes C* 2.1.8 cluster using cassandra-stress,
with the default of CL =1
Stress runs fine for some time, and than start throwing:
java.io.IOException: Operation x10 on key(s) [36333635504d4b343130]: Error
executing: (UnavailableException): Not enough replica available
How do I set TTL for cassandra-stress inserts, either in the profile yaml
file (better) or in the command line?
Thanks

My guess is system_traces initialization complete only after any data

Before it does, any attempt to read from it either from nodetool, cqlsh or
streaming to a new node will fail.

When adding a new server, I get a

exception on the cluster (not the new) server (full log below).
Indeed, when I cqlsh to the cluster server, I see the foll

Hi all
I'm using cassandra-stress directly from apache-cassandra-2.1.2/tools/bin
The documentation I found
http://www.datastax.com/documentation/cassandra/2.1/cassandra/tools/toolsCStress_t.html
is either too old or too advance, but does not match what I use.
In particular, I fail to use the -key
