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

The video tutorial explains bidirectional streaming in GRPC, highlighting its functionality and use cases. It describes how clients and servers can exchange multiple messages asynchronously, which is useful for applications like chat protocols. The tutorial also covers the implementation details, including defining request and response messages using protocol buffers.

What is a key feature of bidirectional streaming in gRPC?

• The client and server must send an equal number of messages.

• Messages are sent in a synchronous manner.

• The client and server can send multiple messages independently.

• It only supports unidirectional communication.

In which scenario would bidirectional streaming be most beneficial?

• When a client needs to download a file from a server.

• When a client and server need to exchange large amounts of data asynchronously.

• When a server needs to broadcast a message to multiple clients simultaneously.

• When a client needs to send a single request and receive a single response.

How does bidirectional streaming handle message exchange between client and server?

• Messages are queued and sent one at a time.

• Messages are exchanged in a predefined sequence.

• Messages can be sent and received independently without waiting for a response.

• Messages are sent only after receiving an acknowledgment.

What keyword is used twice in defining bidirectional streaming messages?

• buffer

• async

• channel

• stream
