Amazon DynamoDB adaptive capacity is now instant

[Amazon DynamoDB](https://aws.amazon.com/dynamodb/) now applies adaptive capacity in real time in response to changing application traffic patterns, which helps you maintain uninterrupted performance indefinitely, even for imbalanced workloads. In addition, instant adaptive capacity helps you provision read and write throughput more efficiently instead of overprovisioning to accommodate uneven data access patterns. Instant adaptive capacity is on by default at no additional cost for all DynamoDB tables and global secondary indexes.
