Subject Re: Solr TCP layer
Date Mon, 09 Mar 2015 10:22:58 GMT
Hi Saumitra,

I've been thinking of adding http/2 support for inter node communication
initially and client server communication next in Solr. There's a patch for
SPDY support but now that spdy is deprecated and http/2 is the new standard
we need to wait for Jetty 9.3 to release. That will take care of many
bottlenecks in solrcloud communication. The current trunk is already using
jetty 9.2.x which has support for the draft http/2 spec.

A brand new async TCP layer based on netty can be considered but that's a
huge amount of work considering our need to still support simple http, SSL
etc. Frankly for me that effort is better spent optimizing the routing
