Subject [jira] [Commented] (CASSANDRA-9558) Cassandra-stress regression in 2.2
Date Fri, 05 Jun 2015 22:03:03 GMT


Andy Tolbert commented on CASSANDRA-9558:

Thanks [~aboudreault]!  

For reference, [JAVA-738|] was previously
opened to evaluate the pool implementation for protocol version 3+.  I've also opened up [JAVA-802|]
to ensure we incorporate testing java-driver RCs with cassandra-stress to ensure there is
no performance regression as part of the test/release process.   I'll continue doing a performance
evaluation of the driver with cassandra-stress to see if anything obvious sticks out on the
driver side.
