Amazon DynamoDB adaptive capacity now handles imbalanced workloads better by isolating frequently accessed items automatically

Amazon 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. 

Adaptive capacity is on by default and it is provided to you at no additional cost for all DynamoDB tables and global secondary indexes. For more information about DynamoDB adaptive capacity, see Isolate Frequently Accessed Items.
