poorbarcode opened a new pull request, #22890: URL: https://github.com/apache/pulsar/pull/22890
### Motivation **Background** 1. the method `PersistentTopic.addReplicationCluster` will remove orphan replication cursors, see https://github.com/apache/pulsar/pull/19972 2. when a topic is loading up, it will initialize replicators by the cursors named `pulsar.repl.<remote cluster>` **Issue** - Mechanism `2` was called before topic-level policies initializing, so it will remove the replicator and cursor when a topic is loading up. - After the topic level policies are initialized, the broker will create a new replicator with a new cursor(start at the `latest position`), and all the messages in backlog are lost. ### Modifications Fix the issue: make Mechanism `2` being called after the topic-level policies were loaded. ### Documentation <!-- DO NOT REMOVE THIS SECTION.
