Support "best effort" producer flow control within the AMQP 0.10 implementation.
--------------------------------------------------------------------------------
Key: QPID-2935
URL: https://issues.apache.org/jira/browse/QPID-2935
Project: Qpid
Issue Type: New Feature
Components: C++ Broker, C++ Client
Affects Versions: 0.9
Environment: any
Reporter: Ken Giusti
Assignee: Ken Giusti
Fix For: Future
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.
