Amazon ElastiCache now supports real-time aggregations

Amazon ElastiCache now supports aggregation queries, making it easier to filter, group, transform, and summarize data directly in your cache with a single query. Developers can use aggregation queries to build real-time application experiences with latencies as low as microseconds over terabytes of data and results reflecting completed writes.

By running aggregations directly in-memory within ElastiCache, developers can reduce architectural complexity and improve response times without a separate analytics engine. Applications can use aggregations to power faceted navigation, category counts, rollups, and leaderboards. Applications can aggregate over the most up-to-date data to deliver real-time insights such as trending content, popular categories, and top-performing items in e-commerce marketplaces and streaming services. Aggregations can drive AI-powered personalization applications that need fast summaries over search results, and operational dashboards for live monitoring and business analytics.

Aggregations are available in all commercial AWS Regions, AWS GovCloud (US) Regions, and China Regions, for node-based clusters running ElastiCache version 9.0 for Valkey at no additional cost. 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 or above cluster or upgrade an existing cluster using the AWS Management Console, AWS SDK, or AWS CLI. To learn more, read the aggregations blog and see the ElastiCache documentation.
