Attachment: multiproc.patch
> stress.py fixes and improvements
> --------------------------------
>
> Key: CASSANDRA-514
> URL: https://issues.apache.org/jira/browse/CASSANDRA-514
> Project: Cassandra
> Issue Type: Improvement
> Environment: debian amd64 Java(TM) SE Runtime Environment (build 1.6.0_12-b04)
> Reporter: Brandon Williams
> Priority: Minor
> Attachments: multiproc.patch

>
> stress.py cannot currently fully stress cassandra. This is due to at least two reasons:
> 1. It does not use the accelerated thrift protocol (thanks jbellis)
> 2. The GIL is preventing concurrency
> To address this, I've modified it in a backwards-compatible way to support multiprocessing, if available.
> Also, key_generator was providing floats instead of integers, causing the read test to ask for keys that did not exist.
