Ken Giusti commented on QPID-2935:
----------------------------------
As of 2/7/2011: Code functionally complete, and passing simple unit tests. The
following TODO items still pending:
o) Performance regression testing & tuning.
o) Cleanup synchronous completion case in SessionState ~line 267
o) Sends completion on every execution.sync, else hangs. Can this be fixed?
o) Hang in clustered + async store tests. Need debug & fix.
o) Creates a request for IOProcessing on each completion - need to aggregate
these.
o) Reviews pending for management changes.
o) Reviews pending for queue flow limit changes.
> Support "best effort" producer flow control within the AMQP 0.10
> implementation.

> To what extent, if any, could producer flow control be supported on the
> existing (pre-1.0) protocol?
> In the current C++ broker/client implementation, when a queue on the broker
> fills to the point where it cannot accept any more messages
> (--default-queue-limit hit), the broker will forcibly disconnect any client
> that attempts to route a message to that queue. This is an abrupt failure -
> the producing client is not privy to the queue's remaining capacity. The
> broker provides no feedback to the producing client, which could be used to
> throttle the client's message production rate.
> The purpose of this JIRA is to explore the possible methods for implementing
> producer throttling on the current 0.10 C++ codebase.
