Chetan Mehrotra resolved OAK-1567.
----------------------------------
Resolution: Won't Fix
Fix Version/s: (was: 1.0)
0.20
This was required for Blob GC usecase. For now at least for Blob GC this is met
via Mongo specific impl of ReferenceBlobCollectory (OAK-1643). So this is not
required.
If later need is felt to support this for some other case then it can be
reopened
> Return Iterator instead of returning List in DocumentStore.query

> Currently the DocumentStore query method returns List after performing any
> query against backend. In case of Mongo the DBCursor returned [1] implements
> Iterable interface. And in all usage so far the code can work perfectly fine
> with Iterable
> It would be better if we change the api contract to return iterator and allow
> lazy traversal of the NodeDocuments. Further the pagination/batching would be
> handled within the Driver itself and the code above would not have to
> construct there on batching.
