  3. abstract def viewId: String

    View id is used as identifier for snapshots performed by this PersistentView.

    View id is used as identifier for snapshots performed by this PersistentView. This allows the View to keep separate snapshots of data than the PersistentActor originating the message stream.

    The usual case is to have a *different* id set as viewId than persistenceId, although it is possible to share the same id with an PersistentActor - for example to decide about snapshots based on some average or sum, calculated by this view.

    Example:

    class SummingView extends PersistentView {
      override def persistenceId = "count-123"
      override def viewId        = "count-123-sum" // this view is performing summing,
                                                   // so this view's snapshots reside under the "-sum" suffixed id
    
      // ...
