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

The video tutorial explains bidirectional streaming in gRPC, where a client and server can send multiple messages to each other asynchronously. It discusses use cases like chat protocols and long-running connections. The tutorial also covers the implementation details, including defining request and response messages using streams.

What is a key feature of bidirectional streaming in gRPC?

• Only the server can initiate the message stream.

• The client must wait for a response before sending the next message.

• The client and server can send multiple messages independently.

• Messages are sent synchronously.

In which scenario would bidirectional streaming be most beneficial?

• When a single message needs to be sent.

• In a chat application where messages are exchanged continuously.

• For a simple request-response interaction.

• When data needs to be stored in a database.

What is a common use case for bidirectional streaming?

• Rendering a static webpage.

• Sending a single file.

• Implementing a chat protocol.

• Performing a database query.

How is the 'stream' keyword used in bidirectional streaming?

• It is used only once for the server.

• It is used twice, once for the client and once for the server.

• It is used only once for the client.

• It is not used at all.

What must be defined in a bidirectional streaming service?

• Both request and response messages.

• Neither request nor response messages.

• Only a response message.

• Only a request message.
