Amazon ElastiCache now supports real-time full-text, exact-match, and numeric range search

Amazon Web Services has enhanced its ElastiCache service with integrated real-time search capabilities, allowing developers to perform full-text, exact-match, and numeric range searches directly within their cache without requiring a separate search service. The new functionality supports searches across terabytes of data with microsecond latency and can handle millions of search operations per second, making data searchable immediately upon write completion to ensure applications always query the most current information. The search capabilities are designed for frequently updated datasets such as user session details, product inventory, and transaction records. Developers can perform exact-match searches for precise lookups by usernames or content IDs, execute numeric range queries for filtering by transaction amounts or date ranges, and utilize full-text search with prefix, suffix, and fuzzy matching for product discovery applications. Multiple search types can be combined within a single query to enable complex filtering operations. The feature is available at no additional cost across all commercial AWS regions, AWS GovCloud regions, and China regions for node-based clusters running ElastiCache version 9.0 for Valkey. Valkey serves as AWS's recommended open-source, vendor-neutral alternative to Redis, and existing clusters can be upgraded through the AWS Management Console, SDK, or CLI to access the new search functionality.
