Resolution: Flow control are only affects home queue, not routed queue.
Home queue owns the mssages and only home queue stores the messages. The routed queues don't store messages. Thus, flowControl doesn't impact routed queue.
E.g. --------------------------- On Server 1 ==> Messages published to a Topic is bridged to a Remote Queue. Remote queue with flow control routes to home queue On Server 2 ==> Home queue with flow control has consumers --------------------------- You will observe,
a. Configure flow control on home queue only: flow control affects; b. Configure flow control on routed queue only: flow control does not affect; c. Configure flow control on both home queue and routed queue: flow control affects.
