Does Replcache handles split brain

[Huthesh]

HI Team,

We are using ReplCache for a simple cluster of 3 nodes. Nodes are hosted on Kubernetes and we are using Jgroups Kubernetes for forming the cluster.

My question is how does ReplCache handle Split brain?

It doesn't handle partitions: nodes on either side of a partition can be updated separately, leading to data inconsistencies. When a network partition heals, data should be consistent again, but at the cost of one side overwriting data of another side. If you want consistency and partition handling, take a look at jgroups-raft. Cheers
