Amazon DynamoDB Accelerator (DAX) is now available in the EU (London) and EU (Paris) Regions
DAX is now available in the EU (London) and EU (Paris) Regions. You can create DAX clusters using Amazon EC2 R4 and T2 instance types in these AWS Regions for applications that require microsecond latency. DAX provides a fully managed, highly available, in-memory cache for Amazon DynamoDB that can accelerate reads from DynamoDB tables by up to 10 times, even at millions of requests per second.

Now, you can create 20 global secondary indexes per DynamoDB table in the AWS GovCloud (US) Regions. If you need more than 20 global secondary indexes, you can request an increase. In addition, you can now have 100 projected index attributes for both global secondary indexes and local secondary indexes when you specify the ProjectionType of INCLUDE.
Amazon DynamoDB Accelerator (DAX) is now available in the China (Ningxia) Region, Operated by NWCD
DAX is now available in the China (Ningxia) Region, operated by NWCD. You can create DAX clusters in this AWS Region for your DynamoDB applications that require microsecond response times.
You now can configure table settings when you restore a table from your Amazon DynamoDB backups
DynamoDB enables you to restore your data to a new DynamoDB table by using a point-in-time or on-demand backup. Now, you can configure table settings when you restore a table from your DynamoDB backups. Specifically, you can exclude some or all of the local and global secondary indexes from being created with the restored table. You also can change the billing mode and provisioned capacity settings.

DynamoDB adaptive capacity now handles imbalanced workloads better by isolating frequently accessed items automatically. If your application drives disproportionately high traffic to one or more items, DynamoDB will rebalance your partitions such that frequently accessed items do not reside on the same partition. This latest enhancement helps you maintain uninterrupted performance for your workloads. In addition, it helps you reduce costs by enabling you to provision throughput capacity more efficiently, instead of overprovisioning to accommodate uneven data access patterns.
