poorbarcode opened a new pull request, #25915:
URL: https://github.com/apache/pulsar/pull/25915
### Motivation
Replication is stuck due to the Topic GC
- Enable binary way replication between the `primary cluster` and `backup
cluster`
- `primary cluster`: Publishing messages into `primary cluster`
- `backup cluster`: No consumer/producer is registered.
- `backup cluster`: Check topic GC
- No subscriptions
- No producers except `remote producer`
- The topic should be GC
- Disable replication
- The topic will not be deleted since the remote-side producer is still
registered
- `backup cluster`: the topic GC progress is waiting for the remote-producer
to be disconnected.
- It will not be executed since no one wants to delete the topic.
- `backup cluster`: backlog increases because the replicator was closed
- Although the messages copied from the remote end will not be copied back
repeatedly, the replicator still needs to perform a check and then mark delete.
### Modifications
- Do not trigger topic GC if replication is still active
- `brokerReplicationInactiveThresholdSeconds` defines how to determine a
replicator is active
