Subject [Ann] Ansible base Cassandra stress framework for EC2
Date Thu, 03 Sep 2015 18:21:56 GMT
I'm please to share a framework for running Cassandra stress tests on EC2.
https://github.com/cloudius-systems/ansible-cassandra-cluster-stress

The framework is a collection of Ansible playbooks and scripts, allowing to:
- Create a Cassandra cluster (setting server type, version, etc)
- Launch any number of loaders
- Run cassandra-stress on all loaders and collect the results
- Add nodes to a running cluster
- Stop and starts nodes
- Clean old data from servers before each test
- Collect and display relevant metrics on a Collectd+Graphite+Tessera

 server

Use cases I tested using this framework:
* Stress with multiple loaders
* Out Scale
<https://github.com/cloudius-systems/cassandra-test-and-deploy/wiki/Testing-Cassandra-Out-Scale>
(adding
server under stress)
* Testing Cassandra Repair
<https://github.com/cloudius-systems/cassandra-test-and-deploy/wiki/Testing-Cassandra-Repair>

More info in README

the  and Wiki

Some of my future plans include adding YCSB, run on other providers and
more.
Contributions and suggestions will be appreciated!
