Description Sergei Vorobiev 2008-06-19 11:13:13 EDT
message broker should allow for throttling maximum incoming message rate for
accepted messages per AMQP session level
Comment 1 Carl Trieloff 2008-12-22 15:56:15 EST
to also control an AMQP client connection to the maximum rate for messages sent over specific AMQP session to a broker (i.e. limit all the taffic from one client, no matter how many sessions).
Comment 2 Andrew Stitcher 2009-02-03 16:29:48 EST
Client session throttling has now been implemented in qpid C++ broker and client:

It is configured by setting a configuration parameter in qpidd.

The new command line argument is "--max-session-rate"

This imposes a limit on the number of messages transferred per second from the client to the broker on every session.
Comment 3 Andrew Stitcher 2009-02-03 16:32:08 EST
This functionality can be tested by (for example) running the broker with a specified session rate:

qpidd --auth no --max-session-rate 200

Then by running perftest against this broker and seeing that the send rate from client to broker is just less than this rate.
Comment 5 Frantisek Reznicek 2009-02-27 09:12:58 EST
The feature has been implemented, tested using qpidd and perftest with and without --max-session-rate qpidd option.
Done on RHEL 4.7 / 5.3 i386 / x86_64 on packages:
