gRPC [Golang] Master Class Build Modern API and Microservices - Protocol Buffers & Language Interoperability

The video tutorial explains the workings of gRPC and its reliance on Protocol Buffers for efficient communication. It highlights the advantages of Protocol Buffers over JSON, such as reduced payload size and CPU usage. The tutorial also covers the wide range of languages supported by gRPC and the interoperability it offers across different platforms. It emphasizes the ease of code generation and the ability to evolve APIs without breaking existing clients, making Protocol Buffers a preferred choice for gRPC.

What is the role of Protocol Buffers in gRPC?

• To make data human-readable

• To replace all JSON APIs

• To define API endpoints and generate code

• To increase the complexity of the API

What is the primary reason for using Protocol Buffers in gRPC?

• To reduce payload size and increase efficiency

• To support only JSON format

• To make data human-readable

• To complicate the API design

How does Protocol Buffers compare to JSON in terms of CPU usage?

• Both have the same CPU usage

• Protocol Buffers are less CPU intensive

• JSON is less CPU intensive

• Protocol Buffers are more CPU intensive

Why is Protocol Buffers considered efficient for network communication?

• Because it requires more bandwidth

• Because it uses XML format

• Because it is binary and smaller in size

• Because it is text-based

Which of the following is NOT a language officially supported by gRPC?

• Python

• Go

• Java

• HTML

What is a key feature of gRPC in terms of language interoperability?

• It does not support cross-language communication

• It only supports Java and Go

• It requires manual code generation for each language

• It allows automatic code generation for multiple languages

What is the advantage of using Protocol Buffers for API evolution?

• It limits the API to one language

• It makes APIs harder to understand

• It allows API changes without breaking existing clients

• It requires frequent versioning
