Hi, I was looking into the support for Version GC (OAK-1341). For that I had a look at BlobReferenceIterator#loadBatchQuery which currently does a pagination over all Documents which have binaries. The DBCursor returned by Mongo [1] implements the Iterator contract and would lazily fetch the next batch.
So had two queries 1. Should we expose the Iterator as part of DocumentStore API and rely on Mongo to paginate. Probably the ResultSet in DB case can also easily Iterator pattern 2. Cache Handling - Currently fetching document in such pattern for GC handling would also overflow the cache. So should we pass an extra flag to not cache docs from such calls Chetan Mehrotra [1] http://api.mongodb.org/java/2.0/com/mongodb/DBCursor.html
