Scatter-Gather pattern using AWS Lambda and Amazon DynamoDB with CDK
This workflow demonstrates an implementation of the Scatter-Grather pattern using a Map state to call a set of AWS Lambda functions.
The Scatter-Gather pattern 'broadcasts' a request message to a set of responders, then aggregates the results. A typical use case would be getting a quotation for a flight from a number of different providers. In this case the responders are modelled as AWS Lambda functions.
