hasura/graphql-engine ? reverse-engineered prompt

I want to build a backend service that acts as a powerful data layer for my applications. The main idea is that I can connect it to my existing databases, like PostgreSQL, MS SQL Server, or MongoDB, and it should automatically generate a complete, real-time GraphQL API for me. I don't want to spend time writing boilerplate code for CRUD operations.

This service needs to be blazing fast and support live queries so I can build dashboards and other features that update instantly. Security is also crucial, so I'll need a way to define fine-grained permissions and access control rules for different user roles. Finally, I'd like to be able to trigger webhooks or other actions whenever data changes in the database. Please use the latest stable version and architecture for this.
