gRPC [Golang] Master Class Build Modern API and Microservices - ListBlog Server

The video tutorial covers the implementation of a list blog RPC using server streaming. It explains how to handle empty requests, generate code, and implement the Listblog function. The tutorial delves into using MongoDB cursors to retrieve data and handle errors during data decoding and streaming. Finally, it demonstrates how to send data to clients and finalize the stream.

What is the purpose of the list blog RPC in the context of server streaming?

• To handle client-side errors

• To return a stream of blog responses

• To send a single blog response

• To filter blog requests

What is unique about the function signature for server streaming in the Listblog implementation?

• It includes a stream parameter

• It uses a unary call

• It requires a filter parameter

• It returns multiple values

In the context of MongoDB, what does the 'find' function return?

• A cursor and an error

• A list of errors

• A filter and options

• A single document

What is the role of the 'defer' keyword in handling MongoDB cursors?

• To close the cursor eventually

• To open the cursor

• To initialize the cursor

• To handle errors immediately

How is data sent to clients in the server streaming process?

• Using a unary call

• By returning a list

• By closing the cursor

• Through a stream send function

What should be done if an error occurs during the cursor iteration?

• Ignore the error

• Return a status error

• Continue without handling

• Restart the server

What indicates the successful completion of the server streaming process?

• Restarting the server

• Closing the stream with nil

• Returning a non-nil error

• Sending a final blog response
