Vijay commented on CASSANDRA-3590:
----------------------------------
I think more in parallel after retrieving from the queue are always better,
specially with all kinds of delay's introduced by the networks across the
DC's/Public internet can make it un-predictable, i will do some micro benchmark
soon. Atleast will help the cases where there frequent disconnects and we wont
need to wait till the connection is established again.

>
> Currently there is one connection between any given host to another host in
> the cluster, the problem with this is:
> 1) This can become a bottleneck in some cases where the latencies are higher.
> 2) When a connection is dropped we also drop the queue and recreate a new one
> and hence the messages can be lost (Currently hints will take care of it and
> clients also can retry)
> by making it a configurable option to configure the number of connections and
> also making the queue common to those connections the above 2 issues can be
> resolved.
