gRPC [Java] Master Class: Build Modern API and Microservices - Client Streaming API Client Implementation - Part 2 - Ref

The video tutorial explains how to implement a client streaming function using gRPC. It covers creating an asynchronous client, handling server responses with a stream observer, sending data to the server, and using a countdown latch for synchronization. The tutorial concludes with testing the implementation to ensure it works correctly.

What is the significance of calling 'onCompleted' in the request observer?

How do you send messages to the request observer in the client streaming implementation?

What are the expected outputs when the client successfully receives a response from the server?

Discuss the importance of asynchronous programming in the context of client streaming.
