How much can Redis scale?

Redis Enterprise recommends to shard if you have more than 25 GB of data and high number of operations. Other aspect is if you have above 25,000 operations per second, then sharding can improve performance. With less number of operations/second, it can handle up to 50GB of data too.

Can Redis be clustered?

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.

What are Redis connections?

Advertisements. Redis accepts clients’ connections on the configured listening TCP port and on the Unix socket, if enabled. When a new client connection is accepted, the following operations are performed − The client socket is put in non-blocking state since Redis uses multiplexing and non-blocking I/O.
