gRPC [Golang] Master Class Build Modern API and Microservices - What's a Server Streaming API?

The video tutorial introduces gRPC streaming APIs, focusing on server streaming APIs, which allow a client to send one message and receive multiple responses. This is particularly useful for big data applications where large payloads are sent in smaller chunks to ensure successful transfer. The tutorial explains when to use server streaming APIs, such as in live feeds or chat applications, and how to implement them using protocol buffers and RPC definitions.

What is a key difference between server streaming APIs and traditional REST APIs?

• REST APIs are better suited for live feeds.

• REST APIs can handle larger data transfers more efficiently.

• Server streaming APIs do not require HTTP/2.

• Server streaming APIs can send multiple responses for a single request.

In what scenario is a server streaming API particularly useful?

• When the server needs to send a large amount of data in a reliable manner.

• When the server needs to handle multiple clients simultaneously.

• When the server needs to send a small amount of data.

• When the client needs to send multiple requests.

How does server streaming improve the reliability of large data transfers?

• By sending data in a single large message.

• By using a different protocol than HTTP/2.

• By requiring client acknowledgment for each message.

• By breaking down data into smaller, manageable messages.

What keyword is used in protocol buffers to define a server streaming API?

• batch

• async

• buffer

• stream

What is the purpose of the 'stream' keyword in gRPC server streaming APIs?

• To indicate that the server will send a single response.

• To limit the data transfer to a fixed size.

• To specify that the server can send multiple responses over time.

• To ensure the client sends multiple requests.
