This video shows how to build a GraphQL application with multiple DynamoDB tables using AWS AppSync. Many DynamoDB data modeling patterns use a single table to hold multiple entities from your application; however, this single-table design pattern may not be desirable when using DynamoDB with GraphQL applications. In using multiple tables, we are able to create simpler, more focused GraphQL resolvers with more flexible querying.
