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.

Which type of GRPC call involves a single request from the client and a single response from the server?

• Server Streaming

• Client Streaming

• Unary

• Bidirectional Streaming

In which GRPC call type does the server send multiple responses to a single client request?

• Bidirectional Streaming

• Client Streaming

• Server Streaming

• Unary

What is a key advantage of using protocol buffers in GRPC?

• Increased latency

• Reduced performance

• Simplified API definition

• Limited data types

Which GRPC call type allows both the client and server to send a stream of messages to each other?

• Unary

• Bidirectional Streaming

• Server Streaming

• Client Streaming

What is the significance of the 'stream' keyword in defining GRPC APIs?

• It specifies the use of HTTP/1.1

• It indicates a unary call

• It limits the number of messages

• It denotes streaming capabilities
