This project provides support for creating service proxies for GraphQLSchema definitions and on the Vert.x event bus.
Schema proxies are created by wrapping the various GraphQL classes that exist in the graphql.schemas package of graphql-java as Vert.x data objects that can be marshalled to JSON and sent on the event bus.
Clients can subsequently instantiate a proxy of the GraphQL schema. In the proxy any data fetchers and type resolvers that existed in the original schema have been replaced with a service proxy that delegates back to the original schema in the service provider.
This project will be applied to vertx-graphql-service-discovery where it facilitates support for:
- Running a query that is completely off-loaded to the schema publisher by sending the query string and awaiting the JSON result (the default)
- Running a query on the consumer-side using a fine-grained mode of communication (where a message is sent to the schema publisher for each
TypeResolverandDataFetcherthat is encountered during query execution) - Mixed mode of communication where a query is partially executed in the consumer up to a certain point (dependent on metadata) after which the schema publisher takes care of processing the remainder
