Sylvain Lebresne updated CASSANDRA-7231:
----------------------------------------
Attachment: 7231.txt
Attaching simple patch to allow for an optional additional byte to extend the
number of possible "streams" id. The change is made so that it's basically
backward compatible which has the nice property that drivers can start using
this on their own time. Also, since it's backward compatible, the patch don't
bother with checking the protocol version: if someone wants to use this in the
protocol v1 and v2, no particular reason to refuse it, it's just undocumented
there.
> Support more concurrent requests per native transport connection

>
> Right now we only support 127 concurrent requests against a given native
> transport connection. This causes us to waste file handles opening multiple
> connections, increases driver complexity and dilutes writes across multiple
> connections so that batching cannot easily be performed.
> I propose raising this limit substantially, to somewhere in the region of
> 16-64K, and that this is a good time to do it since we're already bumping the
> protocol version.
