How to connect AWS AppSync to MongoDB?

Question

AppSync is good that it is a managed GraphQL service.

But I dont want to use the DynamoDB, can I plug to MongoDB?

How to do it?

Answer 1

You cannot directly connect MongoDB to AppSync, But you can create and attach a Lambda function as the DataSource and put all your configuration & mapper logic there. Here is a small tutorial about how to use Lambda resolvers. For your case, you would have to extend it and add MongoDB specific configuration & logic.
