Building a supergraph with Snowflake and PostgreSQL using Hasura

In this tutorial/guide, we will explain how to build a scalable and efficient backend using Hasura Cloud, Snowflake DB, and PostgreSQL on Neon. These tools allow developers to create a supergraph backend that can handle complex data requirements like joining data across multiple sources and filtering data based on model relations. The process involves setting up Hasura Cloud, integrating Snowflake DB and PostgreSQL on Neon, executing individual queries, and performing nested queries for complex data retrieval. By defining appropriate relationships and foreign keys in Hasura's metadata for both Snowflake and PostgreSQL, users can seamlessly perform nested queries, aggregating data from multiple sources into a single response.
