Amazon 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. DAX does all the heavy lifting required to add in-memory acceleration to your DynamoDB tables, without requiring you to manage cache invalidation, data population, or cluster management. Now you can simply focus on building great applications for your customers without worrying about performance at scale.

Using DAX is easy and requires no modification to your application logic, since DAX is compatible with existing DynamoDB API calls. DAX can be enabled with just a few clicks in the AWS Management Console or using the AWS SDK. Just as with DynamoDB, you only pay for the capacity you provision.

DAX is now generally available in US East (N. Virginia), EU (Ireland), US West (Oregon), Asia Pacific (Tokyo), and US West (N. California) and supports a DAX SDK for Java. To learn more about using DAX with DynamoDB, visit our product page, read Amazon CTO Werner Vogels' blog, and read our DAX documentation.
