This blog post shows how to create a scalable difference checking tool for objects stored in S3 buckets. The Lambda function is invoked when S3 writes new versions of an object to the bucket. This example also shows how to remove earlier versions of object and define a set number of versions to retain.

This blog post shows how to use Step Functions’ features and integrations to orchestrate a batch processing solution. You use two Steps Functions workflows to implement batch processing, with one workflow splitting the original file and a second workflow processing each chunk file.

JSONPath provides the flexibility to work on JSON objects and arrays inside the Step Functions states machine by reducing the amount of utility code. This post uses a sample application to highlight effective use of JSONPath and data filtering strategies that can be used in AWS Step Functions.

This post shows a number of solutions to create and share archetypes or layers across the company. With these archetypes, development teams can quickly bootstrap projects with company standards and best practices.

It’s best practice to store the output of the Lambda function in a different bucket or AWS resource than the source bucket. In cases where you need to store the processed object in the same bucket, I show three different designs to help minimize the risk of recursive invocations.
