srouthu1 opened a new issue #11652:
URL: https://github.com/apache/pulsar/issues/11652
#### Expected behavior
I have created consumer with the following code.
Consumer consumer = client.newConsumer()
.topic("persistent://mytenant/myns/mytopic")
.subscriptionName(userName+"-default")
.subscriptionType(SubscriptionType.Key_Shared).keySharedPolicy(KeySharedPolicy.autoSplitHashRange())
.receiverQueueSize(10)
.deadLetterPolicy(DeadLetterPolicy.builder()
.maxRedeliverCount(3)
.deadLetterTopic("persistent://mytenant/myns/mytopic-userName-default.DLQ")
.build())
.ackTimeout(40,TimeUnit.SECONDS)
.subscribe();
My my publisher sends messages with different keys.
My consumer receives the messages but it does not acknowledge the message
because I want the messages to be moved to dead letter topic.
I am expecting the messages to redelivered to my consumer 3 times and then
they should be published to dead letter topic.
#### Actual behavior
The messages are getting redelivered to my consumer unlimited times. They
never moved to dead letter topic.
If I change the subscription type to shared then the messages are moving to
dead letter topic.
#### System configuration
Pulsar version: Tried with both 2.6.0 and 2.8.0
Pulsar Client: 2.6.0
