Is horizontal scalability of Redis possible to increase performance and data volume?

Redis supports horizontal scalability through the clustering mechanism (Redis Cluster). This allows data to be distributed across multiple nodes, increasing storage capacity and improving performance through parallel query processing.

Key points:

• Data is divided into slots and distributed among nodes.
• The cluster automatically redirects requests to the appropriate node.
• Fault tolerance is ensured through replication.

Thus, Redis can be scaled horizontally, but this requires using Redis Cluster and considering the features of data distribution.
