gRPC for production

This project abstracts away the details of the gRPC server and client configuration.

Here are the main features:

• Health check service — We use the grpc_health_probe utility which allows you to query health of gRPC services that expose service their status through the gRPC Health Checking Protocol.
• Shutdown hook — The library registers a shutdown hook with the gRPC server to ensure that the application is closed gracefully on exit
• Keep alive params — Keepalives are an optional feature but it can be handy to signal how the persistence of the open connection should be kept for further messages
• Custom Server builder with some opinionated production ready settings
• Added ability to recover the system from a Runtime exception in the request
• Added ability to add multiple ordered interceptors
• Handy Server interceptors(Authentication, request cancelled, Audit request/response...)
• Handy Client interceptors(Timeout logs, Audit request, Default timeout...)

Examples

• /Users/alexsouza/projects/my/opensource/grpc-server-java/src/test/java/com/apssouza/grpc/Server.java
• /Users/alexsouza/projects/my/opensource/grpc-server-java/src/test/java/com/apssouza/grpc/Client.java

   List<BindableService> services = new ArrayList<>();
   List<ServerInterceptor> interceptors = Factory.allDefaultInterceptors();
   GrpcServerBuilder builder = GrpcServerBuilder.port(50052);
   GrpcServer grpcServer = builder
           .withServices(services)
           .withInterceptors(interceptors)
           .withFixedThreadPool(4)
           .withMaxConnectionAge(5, TimeUnit.MINUTES)
           .withReflectionEnabled(true)
           .withHealthCheck()
           .build();
   grpcServer.start();
