Complete the code to choose the main protocol used for real-time communication.
The system uses [1] protocol to enable real-time data exchange between clients and servers.
WebSocket is the standard protocol for real-time, full-duplex communication between client and server.
Complete the code to select the component responsible for broadcasting messages to multiple clients.
In the architecture, the [1] handles sending real-time updates to all connected users simultaneously.The Message Broker efficiently distributes messages to multiple clients in real-time systems.
Fix the error in the code to ensure the system supports horizontal scaling of real-time connections.
To scale real-time connections, the system uses [1] to share session state across servers.Distributed Cache allows multiple servers to share session data, enabling horizontal scaling.
Fill both blanks to complete the real-time message flow code snippet.
Client sends a message via [1] to the server, which then publishes it to the [2] for distribution.
Clients use WebSocket for real-time sending, and the Message Broker distributes messages to subscribers.
Fill all three blanks to complete the code for a scalable real-time notification system.
Notifications are sent from [1] to [2] using [3] to ensure low latency and high throughput.
Clients send notifications to the Message Broker, which uses WebSocket to deliver messages quickly.
