gRPC [Java] Master Class: Build Modern API and Microservices - [Solution] FindMaximum API

This lecture covers the implementation of a bidirectional streaming function called 'find maximum'. The function sends a stream of requests and receives a stream of responses, updating the maximum value as new data is received. The server logic is implemented to handle incoming data and respond only when a new maximum is found. The client logic involves sending a predefined list of numbers and handling server responses. The lecture concludes with a demonstration of the server and client interaction, highlighting the efficiency of the streaming process.

What is the primary purpose of the find maximum function?

• To identify the maximum value in a stream

• To sort the numbers in a stream

• To find the minimum value in a stream

• To calculate the average of a stream

In the server-side implementation, what is the initial value of the current maximum?

• A random number

• Zero

• The first number in the stream

• Negative infinity

What happens when a new number is greater than the current maximum on the server side?

• The current maximum is updated and a response is sent

• The server ignores the new number

• The server stops receiving numbers

• The server resets the current maximum

What is the role of the request observer in the client-side implementation?

• To send data to the server

• To shut down the server

• To generate random numbers

• To calculate the maximum value

How does the client handle receiving a new maximum value from the server?

• It sends an error message to the server

• It resets the list of numbers

• It stops sending numbers

• It logs the value and continues sending numbers

During the demonstration, what is the final maximum value received by the client?

• 17

• 30

• 9

• 12

What does the demonstration illustrate about the server's response behavior?

• The server only responds when the maximum value changes

• The server responds to every message received

• The server never responds to the client

• The server responds with the minimum value
