gRPC Maven Dependency

Giriş

- grpc-protobuf ve grpc-stub bağımlılığı kesin gerekiyor. 

- grpc-netty-shaded veya grpc-netty arasındaki farkı bilmiyorum

- Java 9 ve üstü için annotations-api gerekiyor.

Stub Bileşeni

Açıklaması şöyle. Kendi kodumuzu yazarken kullandığımız StreamObserver gibi sınıflar bu bileşenden geliyor.

The Stub layer is what is exposed to most developers and provides type-safe bindings to whatever datamodel/IDL/interface you are adapting. gRPC comes with a plugin to the protocol-buffers compiler that generates Stub interfaces out of .proto files, but bindings to other datamodel/IDL are easy and encouraged.

Transport Bileşeni

Açıklaması şöyle

gRPC comes with three Transport implementations:

- The Netty-based transport is the main transport implementation based on Netty. It is for both the client and the server.

- The OkHttp-based transport is a lightweight transport based on OkHttp. It is mainly for use on Android and is for client only.

- The in-process transport is for when a server is in the same process as the client. It is useful for testing, while also being safe for production use.
