Compatibility with open source Redis Cluster
Redise Pack (RP) does not support Redis Cluster protocol as RP has its own clustering technology that moves the clustering, replication, sharding, HA, etc. from the client to the server side. If you have existing Redis clients and code, they will work directly against a RP cluster with only a connection string change. You point a standard Redis client and code at a RP cluster, then scale the cluster as needed.
For additional details regarding the RP architecture, refer to the System architecture section.
