Announcing Valkey 9.0 for Amazon ElastiCache

[Amazon ElastiCache](https://aws.amazon.com/elasticache/) now supports Valkey 9.0, bringing new capabilities to customers building real-time, AI-driven, and high-throughput applications on AWS. As applications grow more data-intensive and latency-sensitive, teams often face the overhead of managing separate search infrastructure, throughput ceilings that force over-provisioning, and complex workarounds for data lifecycle management and multi-tenant architectures. Valkey 9.0 addresses these challenges directly with built-in search, engine-level performance improvements, and new operational flexibility. Valkey 9.0 for Amazon ElastiCache introduces [full-text and hybrid search](https://valkey.io/blog/valkey-search-1%5F2/) that expands on existing vector similarity functionality to provide real-time full-text search, semantic retrieval, filtering, and aggregations over terabytes of data with microsecond latency and throughput up to millions of requests per second. Valkey 9.0 also delivers up to [40% higher throughput for pipelined w](https://valkey.io/blog/introducing-valkey-9/#:~:text=Pipeline%20Memory%20Prefetch%3A%20Memory%20prefetching%20when%20pipelining%2C%20yielding%20up%20to%2040%25%20higher%20throughput%2C)[orkloads](https://valkey.io/blog/introducing-valkey-9/#:~:text=Memory%20Prefetch%3A-,Memory,-prefetching%20when%20pipelining) through engine-level optimizations including faster command parsing and improved memory prefetching. Valkey 9.0 also introduces [hash field expiration](https://valkey.io/blog/hash-fields-expiration/) that allow TTLs to be applied to individual fields within a hash for fine-grained data lifecycle management and [multi-database support](https://valkey.io/blog/numbered-databases/) in cluster mode enabled deployments, providing lightweight logical namespaces to simplify multi-tenant architectures and migrations from standalone environments. These and more than [100 additional enhancements](https://github.com/valkey-io/valkey/releases?q=valkey+9&expanded=true) together bring the performance, functionality, and operational flexibility needed to power increasingly demanding real-time and AI-driven workloads. Valkey 9.0 is available for ElastiCache node-based clusters and serverlesss caches at no additional cost in all commercial AWS Regions, AWS GovCloud (US) Regions, and China Regions. Valkey is the most permissive open source and vendor-neutral alternative to Redis and the recommended engine on ElastiCache. To get started, create a new Valkey 9.0 cluster or upgrade an existing cluster using the AWS Management Console, AWS SDK, or AWS CLI.
