The Amazon DynamoDB Accelerator (DAX) SDK for Java 2.x is now available and is compatible with the AWS SDK for Java 2.x. You can build Java applications with accelerated access to DynamoDB and benefit from non-blocking I/O and other features of the latest AWS SDK for Java.

DAX provides a fully managed, highly available, in-memory cache for DynamoDB that can accelerate reads from DynamoDB tables by up to 10 times, even at millions of requests per second. DAX does all the heavy lifting required to add in-memory acceleration to your DynamoDB tables. DAX is API-compatible with DynamoDB, so you don’t have to change your application logic to use DAX. Just provision a DAX cluster, use the DAX client SDK to point your existing DynamoDB API calls to the DAX cluster, and let DAX handle the rest.

For DAX Regional availability information, see the “Service endpoints” section on Amazon DynamoDB endpoints and quotas. Pricing details are available on the Amazon DynamoDB pricing page. To get started with the DAX SDK for Java 2.x, see Java and DAX.
