AWS Amplify now orchestrates multiple Amazon DynamoDB GSI updates in a single deployment

The Amplify CLI now gives developers the ability to make multiple global secondary index (GSI) updates to their Amazon DynamoDB tables in a single deployment, enabling faster and safer data model iterations. AWS Amplify CLI is a command line toolchain that helps frontend web and mobile developers create cloud backends and connect them to their app for common use cases, like managing app data using AWS AppSync and Amazon DynamoDB.
