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

The video tutorial explains the workings of GRPC and the importance of protocol buffers. It highlights the advantages of using protocol buffers over JSON, such as reduced payload size and lower CPU usage. The tutorial also covers GRPC's support for multiple languages and its ability to generate code for different languages, facilitating cross-language communication. The benefits of protocol buffers, including efficient data serialization and API evolution without breaking clients, are also discussed.

What is a key reason for using protocol buffers over JSON in GRPC?

• Protocol buffers have a larger payload size.

• Protocol buffers are human-readable.

• Protocol buffers are less efficient than JSON.

• Protocol buffers reduce network bandwidth usage.

How do protocol buffers benefit devices with limited resources?

• They increase CPU usage.

• They reduce CPU cycles needed for parsing.

• They require more memory.

• They are less efficient for communication.

Why is protocol buffers considered efficient for network communication?

• They are slower to parse than JSON.

• They require more bandwidth.

• They are binary and smaller in size.

• They are text-based and easy to read.

Which of the following is NOT an officially supported language by GRPC?

• HTML

• Python

• Java

• Ruby

What is the advantage of GRPC's ability to generate code for different languages?

• It requires manual code writing for each language.

• It allows microservices to interact across different languages.

• It limits the use of protocol buffers.

• It restricts the use of GRPC to a single language.

What is a benefit of using protocol buffers for API definition?

• APIs become harder to evolve.

• APIs are tied to a specific language.

• APIs require more versioning.

• APIs can evolve without breaking existing clients.

How does GRPC ensure compatibility across different programming languages?

• By using language-specific APIs.

• By using a common framework and protocol buffers.

• By restricting to a single programming language.

• By generating code manually for each language.
