AWS API Gateway: How to aggregate results?

Question

I am investigating AWS API Gateway and I keep seeing that you can use it to "aggregate the results from multiple old-school RPC-style web service calls into a single response".

However, I cannot find anything on how to achieve this.

I have looked through the Method Execution options but only see how to define a single endpoint URL.

Is aggregation only possible using a lambda function or is there a way to configure data aggregation within API Gateway?

Answer 1

I believe you are referring to Amazon API Gateway – Build and Run Scalable Application Backends

This type of aggregation is possible, but you would need to implement it, according to your requirements. It is not a feature of the service per se, but the service allows you to implement that, if you desire.

The point that they are making is that with a new single API call that you implement, you could then aggregate the results from multiple old-school RPC-style web service calls into a single response.

The implementation is up to you.
