Advanced Data Downloading With AWS Step Functions

Read Original

This article details an advanced implementation of the AWS Step Functions Downloader Pattern. It demonstrates how to query multiple pages of an API in parallel using Map states, use ResultSelectors to manage the Step Functions output size limit, and aggregate data before storing thousands of entries in DynamoDB. It uses the EVE Online market API as a practical example to explain the technical workflow and its limitations.
