Hi all, When I tried to fix a problem related to replicator https://github.com/apache/pulsar/pull/17154 It surprised me that the message deduplication will not work by default with the replicator. I always thought it was enabled for replicators by default. Details to see [0].
I think we should enable the deduplication for the replicator. Otherwise, we will see duplicated messages on the remote cluster. And the producer of the replicator always has a fixed producer name, this will make the message deduplication work properly. The test introduced in https://github.com/apache/pulsar/pull/17154 will check the message replication ordering. Without the message deduplication enabled, the test is flaky with received duplicated messages. After enabling, everything is fine.
