Zero-to-Federation in 60 Seconds: How a GraphQL Middleware Replaced 500+ Legac…
summary
Red Hat replaces 500+ custom REST APIs with a lightweight GraphQL middleware that auto-introspects a broken Salesforce introspection by reconstructing a valid SDL, injects Apollo Federation directives like @key and @shareable while prefixing type names to avoid collisions, rewrites client queries using GraphQL aliases so Salesforce never sees prefixed names, and translates Keycloak JWTs into Salesforce OAuth tokens on the fly; hourly introspection syncs upstream schema changes and the migration that was estimated at 3+ years completes in weeks.
