How the Optimized Amazon Batch integration is different than the Amazon BatchAmazon SDK integration

Note that there are no optimizations for the Request Response or Wait for a Callback with the Task Token integration patterns.

Note

Parameters in Step Functions are expressed in PascalCase, even when the native service API is camelCase.

The following includes a Task state that submits an Amazon Batch job and waits for it to complete.
