I am still confused with Node, Cluster, Active Data and Replica Data.
Let’s say, I have 2 clusters.
1 cluster has 2 servers.
Each server has 1 Active Node and 1 Replica Node
This is what I am understanding:
(1)Active Node :Doc1, Doc2, Doc3
(2)Replica Node: Doc2, Doc4, Doc6
(1)Active Node :Doc4, Doc5, Doc6
(2)Replica Node: Doc1, Doc3, Doc5
- Docs will be saved across Active nodes.
- Replica Node in each server does not save the completely identical list of doc saved in Active Node in the same server. But all replica docs are saved across the all Replica Nodes
Do I understand correctly so far?
Now if I want to have a DR cluster, should I have a whole set of cluster like the original, then, XDCR data from the original cluster to the DR cluster? If doing so, do I find the same docs are stored in the same node just as in the original cluster?
