Subject [jira] [Commented] (CASSANDRA-8457) nio MessagingService
Date Wed, 15 Feb 2017 16:39:42 GMT


Jeremiah Jordan commented on CASSANDRA-8457:

Is adding more complexity to this already complex patch really the answer here (handling large
messages)?  It seems to me like we should finish up the patch as is and make "handle large
messages" an optimization ticket after we get this in.

Getting streaming to work with this seems like a better place to spend our time.

> 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.
