Amazon DynamoDB Accelerator (DAX) is now compatible with the Amazon DynamoDB TransactWriteItems and TransactGetItems APIs. You can integrate your DynamoDB application with DAX without making changes to your existing application logic.
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 support for DynamoDB transactions is available today using the DAX SDKs for Java, Node.js, and Go. Support for Python and .NET is coming in early 2019.
To get the latest DAX SDK, see Using the DAX Client in an Application in the DynamoDB Developer Guide.
