Cluster API Architecture

Note: This page only pertains to Redis Enterprise Pack v5.0 Preview.

The Redis Cluster API support in Redis Enterprise Pack (RP) provides a simple mechanism for Cluster enabled Redis clients to learn and know the cluster topology. This enables clients to connect directly to an RP proxy on the node hosting the master shard for the data being operated on. The result is that for all but the initial call to get the cluster topology or reacquire the location of the master shard, the client will connect to the RP endpoint proxy where the master shard is located.

For example, the initial connection from a client might be to cluster node 1, but the client derives from the information it receives that it needs to go directly to another node in the cluster to interact directly with the data for the query. This process can dramatically reduce access times and latency, but also offers near-linear scalability.

When combined with Redis Enterprise Pack’s other high availability features, this solution provides high performance and low latency, all while providing applications the capabilities to cope with topology changes such as adding, removing of nodes, node failovers and so on.
