What will happen to the IDataEvent handler in a load-balanced production environment?

In a load-balanced production environment, the IDataEvent handler will execute only on one node - the one triggering the event. This behavior is due to how event handling is designed in a distributed system. When an event occurs, it is typically handled by the specific node that is responsible for managing that particular request or process.

In this context, load balancing distributes incoming requests across multiple servers to ensure no single server becomes overwhelmed. When an IDataEvent is triggered, the handling of that event needs to be consistent and reliable, which is why it only processes on the node that received the request. This helps maintain data integrity and consistency, as multiple nodes attempting to handle the same event could lead to concurrency issues or conflicts.

Consequently, each node operates independently in response to its workload, and events are not propagated to all nodes simultaneously. This ensures a clearer event-handling logic within the web application.
