Amazon ElastiCache serves hundreds of thousands of customers and processes billions of requests per second with microsecond latency across Valkey, Memcached, and Redis OSS workloads. Many organizations find that Multi-AZ replication and automatic failover in ElastiCache meet their resilience requirements, but as customers increasingly adopt ElastiCache as a persistent data store, as well as a cache, data loss becomes a primary concern.
Today, we are announcing durability for Amazon ElastiCache for Valkey, so that you can use ElastiCache for workloads that cannot tolerate data loss.
In this post, we explain how durability works, walk through the architecture, and share performance results to show that durability doesn’t compromise the microsecond latency customers expect from ElastiCache.
How durability works
Durability in ElastiCache uses a Multi-AZ transactional log to provide data protection with a fast recovery and restart during…
