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

The video tutorial covers implementing a client call for a streaming RPC, testing it against a running server, and ensuring it functions as expected. It explains setting up server streaming using a blocking stub, building requests, and handling responses in Java. The tutorial demonstrates executing the client, expecting 10 messages spaced by one second, and discusses the importance of Java 8 functions. It concludes with a suggestion to try using an asynchronous client for further learning.

What is the primary purpose of creating a blocking stub in a client call setup?

• To enable asynchronous communication

• To ensure synchronous communication

• To improve server performance

• To handle multiple requests simultaneously

In server streaming, what is the role of a Java iterator?

• To iterate over multiple responses from the server

• To handle asynchronous responses

• To send multiple requests to the server

• To manage server-side errors

Which Java version introduced the 'forEachRemaining' function used in handling server responses?

• Java 6

• Java 7

• Java 8

• Java 9

What is the expected output when running the greeting client main?

• Ten 'Hello Stefan' messages spaced out by one second

• A single 'Hello Stefan' message

• A continuous stream of 'Hello Stefan' messages

• An error message indicating a failed connection

What happens when the client sends are complete in the streaming process?

• The iterator stops and the channel shuts down

• The server continues to send responses indefinitely

• The server sends an error message

• The client sends additional requests
