org.camunda.bpm.engine.impl.history.handler.HistoryEventHandler

The interface for implementing an history event handler.

The {@link HistoryEventHandler} is responsible for consuming the event. Many differentimplementations 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 {@link DbHistoryEventHandler} whichpersists events to a database.
