gRPC [Java] Master Class: Build Modern API and Microservices - 4 Types of gRPC APIs

The video tutorial introduces GRPC and its four types of RPC calls: unary, server streaming, client streaming, and bidirectional streaming. It explains each type, highlighting their characteristics and use cases. Unary is the simplest, resembling traditional request-response APIs. Server streaming allows a single request to receive multiple responses. Client streaming involves sending multiple requests with a single response. Bidirectional streaming supports asynchronous communication between client and server. The tutorial also discusses the advantages of GRPC, such as performance and suitability for big data and chat applications. It concludes with a guide on defining GRPC APIs using protocol buffers.
