# Which Problems Are Solved The current maintained gRPC server in combination with a REST (grpc) gateway is getting harder and harder to maintain. Additionally, there have been and still are issues with supporting / displaying `oneOf`s correctly. We therefore decided to exchange the server implementation to connectRPC, which apart from supporting connect as protocol, also also "standard" gRCP clients as well as HTTP/1.1 / rest like clients, e.g. curl directly call the server without any additional gateway. # How the Problems Are Solved - All v2 services are moved to connectRPC implementation. (v1 services are still served as pure grpc servers) - All gRPC server interceptors were migrated / copied to a corresponding connectRPC interceptor. - API.ListGrpcServices and API. ListGrpcMethods were changed to include the connect services and endpoints. - gRPC server reflection was changed to a `StaticReflector` using the `ListGrpcServices` list. - The `grpc.Server` interfaces was split into different combinations to be able to handle the different cases (grpc server and prefixed gateway, connect server with grpc gateway, connect server only, ...) - Docs of services serving connectRPC only with no additional gateway (instance, webkey, project, app, org v2 beta) are changed to expose that - since the plugin is not yet available on buf, we download it using `postinstall` hook of the docs # Additional Changes - WebKey service is added as v2 service (in addition to the current v2beta) # Additional Context closes #9483 --------- Co-authored-by: Elio Bischof <elio@zitadel.com>
