Amazon DynamoDB Accelerator (DAX), today announced the release of the following:
- SDK for Node.js.
- General availability in two new regions, Asia Pacific (Mumbai) and South America (São Paulo). DAX is already available in US East (N. Virginia), EU (Ireland), US West (Oregon), Asia Pacific (Tokyo), and US West (N. California.
- Support for new R4 instances in US East (N. Virginia), EU (Ireland), US West (Oregon), Asia Pacific (Mumbai) and South America (São Paulo). R4 is the next generation of Amazon EC2 Memory Optimized instances, with 2X the cache sizes of current R3 instances, well-suited for memory-intensive, latency-sensitive workloads such as DAX.
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.
