Amazon ElastiCache now supports Valkey 9.0. This brings the latest community-driven innovations from the Valkey open source project to address the performance and capability requirements of applications as they grow more data-intensive and latency-sensitive, such as real-time analytics, AI-driven retrieval, and high-throughput caching. For example, operating separate search infrastructure in addition to the cache adds cost and latency. High-volume pipelined workloads hit throughput ceilings that force over-provisioning.
