Hello Group, I have a requirement in one of the production systems where I need to be able to migrate entire dataset from Cluster A (Azure Region A) to Cluster B (Azure Region B).
Each cluster have 3 Cassandra nodes (RF=3) running used by different applications. Few of the applications are common is Cluster A and Cluster B thereby sharing same keyspace/table names. Need suggestion for the best possible migration strategy here considering - 1. No Application code changes possible - Minor config/infra changes can be considered. 2. Zero data loss. 3. No/Minimal downtime. It'd be great to hear ideas from all of you based on your experiences. Cassandra Version - Cassandra 3.0.13 on both sides. Total Data size - Cluster A: 70 GB, Cluster B: 15 GB *Thanks & Regards,* *Ankit Gadhiya*
