I am using Active MQ 5.14.2 with spring boot for developing a Pub Sub model
using Topic .
Following is the problem.:
1. Producer P1 fires an Event/Message M1 for subscriber S1 and S2.
Subscriber S1 is fine and displayed the EnQueue and DeQueue of Message M1.
But the Subsciber S2, because of a program exception retry to consume M1
since I have used
RedeliveryPolicy.
policy.setMaximumRedeliveries(5);
policy.setInitialRedeliveryDelay(1000);
policy.setRedeliveryDelay(10000);
Now when the M1 is sent again and again for 5 times with an iteration, the
Subscriber S2 is blocked for subsequent Messages M2 and M3 which were
published after M1.
Is there a way that the subscriber S2 can consume M2 and M3 while the 5
redeliveries are happening for M1.What I have experienced is that the
Message M2 and M3 is blocked for Subscriber S2 till M1 goes to Dead Letter
Queue as a Poison Pill.
This simply makes my system slow.
Also, I have setDispatchAsync to true but nothing changes.
ActiveMQConnection connection = (ActiveMQConnection)
connectionFactory.createConnection();
/* Create Session Acknowledgement */
connection.createSession(false, Session.CLIENT_ACKNOWLEDGE);
connection.setDispatchAsync(true);
connection.setUseAsyncSend(true);
Please let me know is there is a way to handle this scenario to prevent S2
waiting for Message M1 to die before it could consume M2 and M3.

Are all the subscribers using the same Session?
