Performance question - Atlas data api vs graphql api vs realm-web sdk

MongoDB Atlas App Services & Realm

I am considering MongoDB as a database for websites that require a mostly read-heavy workload.

Which data options in MongoDB Atlas have the highest performance for reading data?
Data API, GraphQL, or Realm web SDK?

I can’t use the node.js driver as I am planning to run the website in a serverless environment.

Hi Arpan_Patel,

The Data API and Realm Web SDK should have similar performance for read operations; the primary benefit of the Web SDK is automation and built-in authentication whereas the Data API provides a RESTful API interface, making it easy to interact with MongoDB through HTTP endpoints and a standardized API that follows REST principles.

GraphQL would be the slowest because it has to generate schemas, so I would recommend one of the above offerings.

Thanks for answering it.
Also is there a performance difference in using data API’s built-in post endpoint vs creating a custom GET endpoint to read the data from the same collection?

The Data API endpoints are automatically generated CRUD endpoints built on top of HTTPS Endpoints. So there is no difference between using the findOne Data API endpoint vs creating your own custom GET HTTPS Endpoint that does the same thing.
