gRPC [Golang] Master Class Build Modern API and Microservices - gRPC Services in the Real Word

The video tutorial explores the use of gRPC in Google Cloud services, focusing on Google Pubsub and Spanner. It examines the structure of proto files, highlighting the importance of documentation and comments. The tutorial also covers RPCs, REST API integration via gRPC Gateway, and introduces Google's experimental streaming API. The course concludes by encouraging learners to explore real-life proto files for better understanding.

What is the primary purpose of using comments in gRPC service definitions?

• To make the code look longer

• To define how the code should be documented

• To reduce the file size

• To confuse the developers

Which syntax version is used in the Google Pubsub proto file?

• proto 3

• proto 4

• proto 2

• proto 1

What is the role of the gRPC Gateway in the context of REST APIs?

• To convert REST APIs to SOAP

• To allow gRPC services to be accessed as REST APIs

• To disable REST API access

• To encrypt REST API requests

What type of streaming API is described as an experimental feature in the transcript?

• Unidirectional streaming

• Bidirectional streaming

• No streaming

• Multidirectional streaming

What is the main difference between the proto files for Pubsub and Spanner according to the transcript?

• Spanner does not use comments

• Spanner uses a different syntax version

• Spanner has fewer RPCs and messages

• Spanner has more RPCs and messages
