Hi Raju, Just wanted clarify that you’re using 'in-memory" bucket i.e. Memcached for your application. If that’s correct then you can read-up on the supported capabilities for Memcached bucket. In short rebalance, failover, intra-replication and cross datacenter-replication are not supported for Memcached bucket. You should consider using Couchbase bucket in which case you get the in-memory capabilities and also availability and disaster recovery.
Thanks!
