Redis Cluster provides a way to run a Redis installation where data is automatically sharded across multiple Redis nodes.

Redis Cluster provides a way to run a Redis installation where data is automatically sharded across multiple Redis nodes.

Redis Cluster also provides some degree of availability during partitions, that is in practical terms the ability to continue the operations when some nodes fail or are not able to communicate. However the cluster stops to operate in the event of larger failures (for example when the majority of masters are unavailable).

So in practical terms, what you get with Redis Cluster?

  • The ability to automatically split your dataset among multiple nodes.

  • The ability to continue operations when a subset of the nodes are experiencing failures or are unable to communicate with the rest of the cluster.
