Julian Reschke commented on OAK-3634:
-------------------------------------
[~mreutegg]: if I understand correctly, the change clears the cache at the end
of the method call. Doesn't that mean that we still have time window in which
the cache contains the incorrect entries? Shouldn't we avoid updating the cache
in the first place?
> RDB/MongoDocumentStore may return stale documents

> It appears that the implementations of the {{update}} method sometimes
> populate the memory cache with documents that do not reflect any current or
> previous state in the persistence (that is, miss changes made by another
> node).
> (will attach test)
