AWS has added vector, full-text and hybrid search, plus server-side aggregations, to ElastiCache Serverless for Valkey. The company says vector searches can reach up to 99% recall with latency as low as microseconds, and that updates can become searchable in as little as microseconds after writes complete.

The feature is available on Valkey 9 in commercial AWS Regions, AWS GovCloud (US) Regions and the AWS European Sovereign Cloud Region. Customers can create a new serverless cache or upgrade an existing one. AWS says the service is billed based on use and needs no infrastructure management.

## The facts
