DynamoDB Accelerator (DAX) is a fully managed, highly available, in-memory cache for DynamoDB that delivers up to a 10x performance improvement – from milliseconds to microseconds – even at millions of requests per second. Real-time analytics is used by many organizations to support mission-critical decisions on real-time data.The real-time journey typically starts with live dashboards on real-time data and soon moves to automating actions on that data with applications like instant personalization, gaming leaderboards and smart IoT systems. While it works great for smaller scale applications, the limitations it poses in the context of larger scale applications are not well understood. {note} Cache tags are not supported when using the file, dynamodb, or database cache drivers.
