AWS – Amazon DynamoDB Accelerator (DAX) SDK for JavaScript version 3 is now available

The Amazon DAX SDK for JavaScript, version 3 (v3) is now available. You can use this new DAX SDK to build JavaScript applications that benefit from accelerated access to DynamoDB with minimal configuration changes. The AWS SDK for JavaScript v3 offers a modular architecture and features that improve developer productivity.

DAX is a fully managed, highly available, in-memory cache for DynamoDB that can boost read performance by up to 10 times, even at millions of requests per second. It is API compatible with DynamoDB, so you do not need to change your application logic. Simply provision a DAX cluster, update your client to use the new DAX SDK for JavaScript v3, and direct your existing DynamoDB calls to the DAX endpoint.

For information about DAX Regional availability, see the “Service endpoints” section in Amazon DynamoDB endpoints and quotas. To get started with the DAX SDK for JavaScript v3, see Node.js and DAX.
