RobertIndie opened a new pull request #13355:
URL: https://github.com/apache/pulsar/pull/13355
### Motivation
If we enable the DLQ when consuming messages. For some messages that can't
be processed successfully, the messages will be moved to the DLQ, but if we do
not specify the data retention for the namespace or create a subscription for
the DLQ to retain the data, the data of the DLQ topic will be removed
automatically. Therefore, we need to create the initial subscription before
sending messages to the DLQ.
### Modifications
* Add `initSubscriptionName` and `initSubscriptionType` to the
`DeadLetterPolicy`
* Create the initial subscription before creating the deadLetterProducer in
ConsumerImpl.
