Subject [jira] [Commented] (AVRO-625) RPC: permit out-of-order responses
Date Fri, 10 Jan 2014 18:20:55 GMT

Doug Cutting commented on AVRO-625:

Perhaps we should use SPDY for Avro?

SPDY provides secure sessions that multiplex many streams over a single connection.  A handshake
need only be performed once per session.  Each request can use a new stream, so responses

For Java, Jetty provides a client and server implementation.  There SPDY libraries for C,
Ruby & Python.  For C# the best I can find is the one referenced from:

> It should be possible, when using a stateful, connection-based transport, for a client
to complete a second request over a connection before the first request has returned.  In
other words, responses should be permitted to arrive out-of-order.
