Data Federation in GraphQL using Hasura Remote Joins and Gatsby Source Plugins

This post discusses the use of Data Federation in GraphQL using Hasura Remote Joins and Gatsby Source Plugins. It introduces the concept of Data Federation, which allows for aggregating data from distributed sources into a single, common data model without containing the actual data. The post then explains how Remote Joins in Hasura enables Data Federation via GraphQL by joining data across databases and other sources like APIs. Gatsby Source Plugins are also introduced as a way to pull data into a site using GraphQL from various data sources such as APIs, databases, CMSs, local files, etc. The post provides an example use case of combining Hasura with Gatsby's GraphQL APIs and explores several potential use cases for Data Federation in this context.
