public interface HistoryEventHandler

The interface for implementing an history event handler.

The HistoryEventHandler is responsible for consuming the event. Many different implementations of this interface can be imagined. Some implementations might persist the event to a database, others might persist the event to a message queue and handle it asynchronously.

The default implementation of this interface is DbHistoryEventHandler which persists events to a database.
