The requirement is to do mariadb replication across two kubernetes cluster
I have one k8s cluster and each cluster running 3 mariadb pods which are syncing data using galera, it is working fine as expected. Now a other new k8s cluster is added in the network again having 3 mariadb pods and syncing data using galera.
What approach need to be followed to sync/replicate date across all 6 nodes from both cluster.
if someone can help with the approach and steps would be fine.
