In this episode, David will be building a document processing workflow using SAM Accelerate, Step Functions, Lambda, Textract, and S3. This workflow will be triggered when a PDF file is uploaded to an S3 bucket. It will grab metadata from the PDF, extract text from the document with Textract, and then insert the resulting data into DynamoDB. All of this will be managed by a Step Function. You can see an image of the workflow below:
