What is the event bus pattern and how does it affect performance?

The event bus pattern is a design pattern that facilitates communication between different components in a system. It allows components to publish and subscribe to events, promoting loose coupling. Regarding performance, it can improve scalability but may introduce latency if not managed properly.

Can you explain how it improves scalability?

Certainly! By decoupling components, the event bus pattern allows multiple components to operate independently. This means you can scale individual components based on demand without affecting the entire system, leading to better resource utilization.

What are some potential downsides of using the event bus pattern?

Some downsides include increased complexity in debugging, potential message loss if not handled correctly, and the overhead of managing the event bus itself.

How can I mitigate the downsides?

You can mitigate downsides by implementing robust error handling, using message persistence, and monitoring the event bus for performance issues.
