Amazon ElastiCache now supports real-time full-text, exact-match, and numeric range search directly in your cache without a separate search service. Applications can use ElastiCache to search terabytes of data with latency as low as microseconds and throughput up to millions of search operations per second. Developers can combine any of these search types in a single query to power real-time, scalable search across frequently changing data. ElastiCache makes data searchable as soon as writes complete, so applications always search the most current data. This is ideal for frequently updated datasets such as user session details, product inventory, and transaction records. Exact-match search enables instant lookup of records by precise values such as usernames, content IDs, or genres across streaming and gaming applications. Numeric range queries enable filtering by transaction amounts, date ranges, or player scores in financial applications and leaderboards. Developers can use full-text search with prefix, suffix, and fuzzy matching to power product discovery in e-commerce platforms, or combine search types to filter by category, price, and ratings. Full-text, exact-match, and numeric range search is 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.
