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

The video tutorial introduces gRPC and its four types of APIs: unary, server streaming, client streaming, and bidirectional streaming. It explains each type, highlighting their characteristics and use cases. Unary APIs are similar to traditional request-response models, while streaming APIs allow for continuous data flow. Bidirectional streaming enables asynchronous communication between client and server. The tutorial also covers how to define these APIs using protocol buffers, emphasizing the simplicity of defining contracts in gRPC.

Which type of gRPC call is similar to a traditional request-response model?

• Server Streaming

• Unary

• Bidirectional Streaming

• Client Streaming

In server streaming, how does the server send data to the client?

• By sending multiple requests

• As a continuous stream of responses

• In a single response

• By waiting for client confirmation

What is a key characteristic of bidirectional streaming in gRPC?

• The client sends a single request

• The server sends a single response

• Both client and server can send multiple messages asynchronously

• The server waits for all client messages before responding

What keyword is used in Protocol Buffers to define a streaming API?

• async

• channel

• stream

• buffer

How does gRPC enhance traditional APIs?

• By using XML for data serialization

• By eliminating the need for HTTP

• By providing better performance with Protocol Buffers

• By supporting only unary calls
