> the current persistence granularity is _single nodes_ (a node consists of properties and child node information).
> instead of storing/retrieving single nodes it would IMO make sense to store subtree aggregates of specific nodes. the choice of granularity could be based on simple filter criteria (e.g. property value).
> dynamic persistence granularity would help reducing the number of records and r/w operations on the underlying store, thus improving performance.
