cbornet opened a new issue #2962: Geo Replication and consumer failover
URL: https://github.com/apache/pulsar/issues/2962
 
 
   Hi,
   
   Could you give guidance on how to failover consumers in an async Geo Replication scenario ?
   When a Pulsar cluster crashes in one region  (or is shutdown for whatever reason, or is too slow), it's a common need to failover the producers and consumers to the replicated cluster. But AFAIK, the subscription offsets are not preserved during replication (same as Kafka) so there's a need to reset the subscription to the last received message. For Kafka, in Confluent Entreprise v5, the consumers will send their consumption timestamps to a dedicated topic that can then be used to get the offset on the replicated cluster. Is there something similar in Pulsar ? Or maybe something better ?
