Hi All, In an Active-Active MM2 (MirrorMaker 2) setup, I have the following Data Centres (DC1,DC2) :
DC1: Topic T1 Kafka Streams which consumes from T1 and updates a local state store (example : "MyStateStore"). the applicationId is "myapp". DC2: Topic T1 The MM2 process replicates the records from T1 to DC1.T1 on this data centre. MM2 also replicates myapp-MyStateStore-changelog to DC1.myapp-MyStateStore-changelog. MM2 configuration: "sync.group.offsets.enabled = true". Questions : When I failover "myapp" to the DC2, how will the application get access to the State Store ? In my code I can only specify the name of the statestore from which to consume. Is there a way I can get access to the State Store in this site as well ? My theory is that in DC2 will only have records in the change log topic called DC1.myapp-MyStateStore-changelog so all state is essentially lost when I failover to DC2. Regards. Neeraj
