Amazon ElastiCache version 8.0 for Valkey brings faster scaling and improved memory efficiency

Today, Amazon ElastiCache introduces support for Valkey 8.0, the latest Valkey major version. This release brings faster scaling for ElastiCache Serverless for Valkey and improved memory efficiency on node-based ElastiCache, compared to previous versions of ElastiCache for Valkey and Redis OSS. Valkey is an open-source, high-performance key-value datastore stewarded by the Linux Foundation and is a drop-in replacement for Redis OSS. Backed by over 40 companies, Valkey has seen rapid adoption since its inception in March 2024.

Hundreds of thousands of customers use ElastiCache to scale their applications, improve performance, and optimize costs. ElastiCache Serverless version 8.0 for Valkey scales to 5 million requests per second (RPS) per cache in minutes, up to 5x faster than Valkey 7.2, with microsecond read latency. With node-based ElastiCache, you can benefit from improved memory efficiency, with 32 bytes less memory per key compared to ElastiCache version 7.2 for Valkey and ElastiCache for Redis OSS. AWS has made significant contributions to open source Valkey in the areas of performance, scalability, and memory optimizations, and we are bringing these benefits into ElastiCache version 8.0 for Valkey.

ElastiCache version 8.0 for Valkey is now available in all AWS regions. You can upgrade from ElastiCache version 7.2 for Valkey or any ElastiCache for Redis OSS version to ElastiCache version 8.0 for Valkey in a few clicks without downtime. You can get started using the AWS Management Console, Software Development Kit (SDK), or Command Line Interface (CLI).
