Hi Rajesh, If you want to split a single cluster across two data centers, this will lead a performance penalty due to large network latency.
If you asked about data replication between clusters via WAN, Apache Ignite doesn't support this at the moment. I think there are two ways to do: make own implementation or use commercial solutions like https://docs.gridgain.com/docs/data-center-replication.
