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.

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

What was the final outcome of the protocol buffer definition process as mentioned in the text?
