merlimat commented on issue #2400: PIP-22: Dead Letter Topic URL: https://github.com/apache/incubator-pulsar/pull/2400#issuecomment-415977386 > @merlimat @rdhabalia can you confirm the summary is correct? 👍 > frankly speaking, I am not sure about the producer concerns: producer memory, authorization, and schema. if you model DLQ topic as replicating messages whose delivery count is larger than max-delivery-count, it should be no difference than cross-data-center replication. I'm not saying it's not possible to make it efficient and safe, but that it would require more work to cover all conditions > @sijie Yes, it's approach work for me. We should send a request to broker for get redelivery count per message when consumer send redeliverUnackMessages request before? The dispatcher could include the redelivery count when pushing messages to the consumer (in `CommandMessage`).
