gRPC [Java] Master Class: Build Modern API and Microservices - What's a Client Streaming API?

The video tutorial explains client streaming APIs, which allow clients to send multiple messages to a server and receive a single response. It highlights the benefits of using client streaming in scenarios involving large data transfers or expensive server processing. The tutorial also covers how to implement client streaming using protocol buffers by defining request and response messages and adding stream keywords.

What is the primary function of a client streaming API?

• To ensure secure data transmission over HTTP/1.1

• To facilitate real-time data synchronization between client and server

• To enable the client to send multiple messages and receive one response

• To allow the server to send multiple responses to the client

In which scenario is client streaming particularly useful?

• When the server processes data in bulk

• When the client needs to send large amounts of data

• When the server needs to send data in real-time

• When the client needs to receive multiple responses

Why is it beneficial to process messages one by one in client streaming?

• It reduces the server's processing time

• It allows the client to receive responses faster

• It minimizes the risk of data loss

• It enables immediate processing of each message

What keyword is added to indicate client streaming in protocol buffers?

• queue

• async

• stream

• buffer

What must be defined for each RPC request in protocol buffers?

• A single response message

• A request and a response message

• Multiple request messages

• A streaming protocol
