gRPC [Java] Master Class: Build Modern API and Microservices - ReadBlog Server

The video tutorial covers the process of creating a read request in a proto file, generating the necessary proto files using Gradle, and implementing the read blog method in a blog service. It explains how to handle blog IDs, query MongoDB for a blog, and manage potential errors. The tutorial also demonstrates constructing responses and adding logging to the code, concluding with running the server and preparing for client-side implementation.

What is the primary purpose of the 'read blog' RPC in the proto file?

• To delete a blog entry

• To fetch a blog using a blog ID

• To update an existing blog

• To create a new blog entry

In the implementation of the read blog method, what is the first step after receiving a request?

• Connect to the MongoDB database

• Return a read blog response

• Extract the blog ID from the request

• Log the request

What happens if the blog ID does not match any entry in the MongoDB collection?

• The request is ignored

• A 'not found' error is returned

• An error is logged but no response is sent

• A new blog is created

Which method is used to parse the document from MongoDB to construct a blog object?

• getString()

• parseDocument()

• getDocument()

• buildDocument()

What is the final step in constructing a blog response?

• Log the response

• Complete the response observer

• Build the blog object

• Set the blog ID

Why is logging important in the read blog process?

• To monitor each stage of the process

• To debug the MongoDB connection

• To ensure the server is running

• To track the number of requests

What is the next step after running the blog server?

• Write the client code

• Test the server with sample data

• Optimize the server performance

• Deploy the server to production
