Hi Penghui >I'm sorry, I don't fully understand your point here. What is the "support replication on message and topic level"?
>As I understand, are the `allowed-clusters` and `replication-clusters` more concise options? Pulsar support set replication-cluster for per message. After this proposal, the `replication-clusters` at the topic/namespace level could be the default value when the message level is not set, and `allowed-clusters` could be the constraint when setting `replication-cluster` for the message level. I am struggling with whether we should introduce message level into the title of this proposal. Do you have any suggestions for the title of the proposal? BR, Xiangying
