[jira] Created: (QPID-2515) Need to be able to set flow control in
Java on a per destination level
Need to be able to set flow control in Java on a per destination level
----------------------------------------------------------------------
Key: QPID-2515
URL: https://issues.apache.org/jira/browse/QPID-2515
Project: Qpid
Issue Type: Bug
Reporter: Rajith Attapattu
Assignee: Rajith Attapattu
Fix For: 0.7
Currently consumer flow control is set at connection level.
It would nice if "capacity" (in number of messages) could be specified on a per destination basis.
We do not support producer side flow control yet, but when we do this should be easily adapted there as well.
I propose to include capacity as a link property in the new addressing scheme.

----------------------------------------
Added support for this at rev 945945 in Qpid trunk.
However some issues remain.
I have highlighted them here.

Martin Ritchie commented on QPID-2515:
--------------------------------------
The Java Broker supports PFC on the 0-91/0-9/0-8 branch using queue arguments:
x-qpid-capacity
x-qpid-flow-resume-capacity
See here:
http://qpid.apache.org/use-producer-flow-control.html
I'm not sure that reusing these values to configure consumer flow control is the right approach. We should be able to configure the two indepenantly.
Once I'm done with the Slow Consumer Detection work I'm scheduled to work on including Producer Flow Control on the 0-10 code path so would be good if we could work together on how these will interact.
