@Shane Weeden One of the limitations of Redis on K8s is it does not support cross-cluster operations per their documentation. When utilizing ISVA in multiple datacenters, each datacenter having it's own K8s cluster, this presents a challenge.
However, on their REAADB (Reddit Active-Active Database) creation page they mention two geographically different namespaces, although it is somewhat unclear if REAADB supports running across K8s clusters. However, from the ISVA documentation it seems REAADB would be unsupported.
Today, DSC runs fine across multiple multiple K8s/OpenShit clusters. I've utilized various ways to get traffic into it, including nodeport and advanced networking integrations via OVN.
The issue with DSC is that it only supports 4 instances and does not support rate limiting for multiple WRP instances. For multiple datacenters and the rate limiting feature, Redis is of course preferred.
Have you known of any ISVA installations crossing K8s/OpenShift clusters that also utilize Redis doing the same?

Failover for the Redis server
Per documentation above, Redis Sentinel configuration is supported, not redis clusters.

I have what I hope is an easy question and that is does ISVA support Redis Active-Active databases?
