Research direction
Start by locating the AggregateProcessor implementation and its existing state-handling or restart-related tests. Determine what aggregate state must be persisted and restored across Data Prepper restarts; done means the current state survives a restart without losing or misrepresenting aggregates, with coverage for the behavior.
