Pulsar Summit - Europe 2021
No Surprises Geo Replication
The video covers the details on how geo replicated topic works under the hood while also touching lightly on the replicated subscriptions. Then we steer towards the pulsar’s behaviour in various scenarios like updating replicated topic, changes in cluster topology, outages, etc and end with the metrics & configurations to look out for. We also look into configurations to have predictable failover for replicated subscriptions when dealing with unbounded cross-region lag or subscription lag itself.
