Apollo Graphql as API Gateway
By Tarun Sharma
Apollo Graphql as API Gateway
API gateways often define authorization rules, throttling rates, and caching times differently for each route. But since GraphQL uses only one endpoint, it’s nearly impossible to define route-specific rules for anything. Consequently, you may need to write authorization, throttling, and caching logic in a separate layer or perhaps even in your microservices themselves.
