-----------------------------------------
Summary: Make netty pipeline fully async
Key: CASSANDRA-8075
URL: https://issues.apache.org/jira/browse/CASSANDRA-8075
Project: Cassandra
Issue Type: Improvement
Reporter: T Jake Luciani
Fix For: 3.0
Related to CASSANDRA-5239. Netty does much better if we remove the request
thread pool jump.
Here is a benchmark of our netty pipeline returning a static value (so no
actual cassandra processing). When the thread pool is removed we see a
dramatic improvement.

On my laptop using the async branch can match redis bench on the same machine
~160k ops/sec.
