   There is the plan to implement the concept of "replicated subscriptions" in open-source Apache Pulsar, to have precise failover to a different cluster. We didn't get to actually implement it yet, but it's planned for near future. 
   
   Workarounds for that are: 
    * Use active-active consumers (consume and process in both clusters)
    * Do manual failover and reset subscription to a timestamp. eg: Cluster A failed, move consumers to cluster B and rollback to 10 minutes earlier. Some amount of duplicates will occur in this case.
