Amazon ElastiCache for Redis now supports Redis 7. This release brings several new features to Amazon ElastiCache for Redis:

Redis Functions: ElastiCache for Redis 7 adds support for Redis Functions, enabling developers to execute LUA scripts with application logic stored on the ElastiCache cluster, without requiring re-sending the scripts to the server with every connection.

ACL improvements: ElastiCache for Redis 7 adds support for the next version of Redis Access Control Lists (ACLs). With ElastiCache for Redis 7, clients can now specify multiple sets of permissions on specific keys or keyspaces in Redis.

Sharded Pub/Sub: Amazon ElastiCache for Redis 7 now gives you the ability to run Redis’ Pub/Sub functionality in a sharded way when running ElastiCache in Cluster Mode Enabled (CME). Redis’ Pub/Sub capabilities enable publishers to issue messages to any number of subscribers on a channel. With Amazon ElastiCache for Redis 7, channels are bound to a shard in the ElastiCache cluster, eliminating the need to propagate channel information across shards resulting in improved scalability.
