Date Wed, 10 Dec 2014 21:31:15 GMT
Jonathan Ellis created CASSANDRA-8457:
-----------------------------------------

             Summary: nio MessagingService
                 Key: CASSANDRA-8457
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8457
             Project: Cassandra
          Issue Type: New Feature
          Components: Core
            Reporter: Jonathan Ellis
            Assignee: Ariel Weisberg
             Fix For: 3.0


Thread-per-peer (actually two each incoming and outbound) is a big contributor to context
switching, especially for larger clusters.  Let's look at switching to nio, possibly via Netty.
