AWS has announced durability support for Amazon ElastiCache for Valkey, allowing workloads requiring low latency and high availability to prevent data loss. Customers can choose between synchronous or asynchronous writes to meet different data loss tolerance and latency requirements. This enhancement expands ElastiCache's applicability to critical use cases like AI agent memory and payment processing, and is available globally starting with Valkey 9.0.

  • ElastiCache for Valkey introduces durability options

    Amazon ElastiCache for Valkey now supports durability through synchronous or asynchronous write options, enabling workloads that cannot tolerate data loss. Synchronous writes ensure zero data loss across AZs but with higher latency, while asynchronous writes maintain microsecond latency with a potential for minor data loss in rare failure events.

  • Expanded use cases for ElastiCache

    Durability support broadens ElastiCache's use cases beyond caching to include applications sensitive to data loss, such as AI agent memory, knowledge bases for RAG, payment tokenization, and real-time inventory management.

Notes (1) ›
  • Availability and Getting Started

    Durability for ElastiCache is available in all AWS commercial, China, and GovCloud Regions with Valkey 9.0. Users can enable durability via the AWS Management Console, SDK, or CLI when creating new clusters.
