Amazon DynamoDB Accelerator (DAX) is now available in the Amazon Web Services China (Ningxia) Region, operated by NWCD. You can create DAX clusters in this Amazon Web Services Region for your DynamoDB applications that require microsecond response times.
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.
