Amazon MemoryDB for Redis now supports Redis 7. This release brings several new features to MemoryDB:
- Redis Functions: MemoryDB adds support for Redis Functions, and provides a managed experience enabling developers to execute LUA scripts with application logic durably stored on the MemoryDB cluster.
- ACL improvements: MemoryDB adds support for the next version of Redis Access Control Lists (ACLs). With MemoryDB, clients can now specify multiple sets of permissions on specific keys or keyspaces in Redis.
- Sharded Pub/Sub: MemoryDB now gives you the ability to run Redis’ Pub/Sub functionality in a sharded way. With MemoryDB, channels are bound to a shard in the MemoryDB cluster, eliminating the need to propagate channel information across shards resulting in improved scalability.
- Enhanced I/O Multiplexing: MemoryDB now includes enhanced I/O multiplexing, which delivers significant improvements to throughput and latency at scale. As an example, when using r6g.4xlarge node and running 5200 concurrent clients, you can achieve up to 46% increased throughput (read and write operations per second) and up to 21% decreased P99 latency, compared with Amazon MemoryDB for Redis 6.
