When to use it… and when not
The datacenter to datacenter replication is a good solution in all cases where you want to replicate data from one cluster to another without the requirement that the data is available immediately in the other cluster.
The datacenter to datacenter replication is not a good solution when one of the following applies:
- You want to replicate data from cluster A to cluster B and from cluster B to cluster A at the same time.
- You need synchronous replication between 2 clusters.
- There is no network connection between cluster A and B.
- You want complete control over which database, collection & documents are replicate and which not.
