A GraphQL processor executes the user provided GraphQL query to fetch documents from the federated gateway. Reusing the index itself to power reverse lookups enabled us to keep all the logic for handling related entities contained within our systems and shield our users from that complexity. We needed to make this step much easier.

Since we index the data as-is from the federated graph, the indexing query itself acts as self-documentation. This integration with the federation gateway allows the search DGS to just return the matching entity keys from the search index instead of the whole matching document(s). Below are a couple of examples.
