Subject [jira] [Commented] (SOLR-7339) Upgrade Jetty from 9.2 to 9.3
Date Wed, 17 Feb 2016 15:01:18 GMT


Mark Miller commented on SOLR-7339:

Well, at least they are repeatable fails.

Not sure what it is yet, but fails seem to have the following that I don't see in passes:

23813 DEBUG (qtp1185380035-63) [    ] o.e.j.i.ManagedSelector

> Jetty 9.3 offers support for HTTP/2. Interest in HTTP/2 or its predecessor SPDY was shown
in [SOLR-6699|] and [on the mailing list|].
> Among the HTTP/2 benefits over HTTP/1.1 relevant to Solr are:
> * multiplexing requests over a single TCP connection ("streams")
> * canceling a single request without closing the TCP connection
> * removing [head-of-line blocking|]
> * header compression
> Caveats:
> * Jetty 9.3 is at M2, not released.
> * Full Solr support for HTTP/2 would require more work than just upgrading Jetty. The
server configuration would need to change and a new HTTP client ([Jetty's own client|],
[Square's OkHttp|], [etc.|])
would need to be selected and wired up. Perhaps this is worthy of a branch?
