This video shows how to use single-table DynamoDB design with GraphQL. Single-table is a DynamoDB pattern in which multiple entities for an application are combined into a single DynamoDB table. Using AWS AppSync, we set up a blog hosting application that contains Sites, Posts, and Comments in a single table. You will learn how to use “lookaheads” in your GraphQL resolvers to understand the nested relations that are requested in your queries. After watching this video, you will understand the tradeoffs of using single-table design in your GraphQL application.
