> Both the MongoDocumentStore and the RDBDocumentStore maintain a "_modCount" property, which uniquely identifies a version of a document in the persistence.
> Sometimes, we read data from the persistence although we already might have the document cached. This happens:
> a) when the cached document is older than what the caller asked for
> b) when running a query (for instance when looking up children of a node)
> In both cases, we currently replace the cache entry with a newly built NodeDocument.
> It would make sense to re-use the existing document instead. (This would probably require modifying the "created" timestamp, but would avoid the trouble of having to update the cache at all)
