gRPC [Golang] Master Class Build Modern API and Microservices - GreetManyTimes API Definition

The video tutorial introduces the 'greet many times' API, a server streaming API using gRPC. It explains how to define this API in protocol buffer files, highlighting the use of the 'stream' keyword for server streaming. The tutorial covers defining the necessary request and response messages and emphasizes the importance of creating new message types for new RPCs. Finally, it demonstrates generating code from the protocol buffer definitions and confirms successful implementation.

What is the primary function of the 'greet many times' API?

• To send multiple requests and receive a single response

• To send a single request and receive multiple responses

• To send and receive a single request and response

• To send multiple requests and receive multiple responses

What does the 'greet many times' response contain?

• A single greeting

• A result string

• A list of errors

• A status code

What keyword is used to define a server streaming RPC in protocol buffers?

• pipe

• channel

• flow

• stream

Why is it important to create new request and response message types for each new RPC?

• To reduce the size of the protocol buffer files

• To improve the speed of the API

• To ensure backward compatibility

• To allow for future changes and avoid conflicts

What is the purpose of generating code after defining the protocol buffer file?

• To optimize the performance of the API

• To check for any runtime errors

• To ensure the RPC is correctly implemented in the code

• To verify the syntax of the protocol buffer file
