Building realtime applications is hard.

A scalable solution to this problem involves many cumbersome steps:

• Hooking into replication logs of the database servers, or writing custom data invalidating logic for realtime UI components.
• Adding messaging infrastructure (e.g. RabbitMQ) to your project.
• Writing sophisticated routing logic to avoid broadcasting every message to every web server.
• Reimplementing database functionality in the backend if your app requires realtime computation (e.g. realtime leaderboards).
  
  All this requires enormous commitment of time and engineering resources.
