Dmitry Kan commented on SOLR-1726:
----------------------------------
"Scrolling is not intended for real time user requests, it is intended for
cases like scrolling over large portions of data that exists within
elasticsearch to reindex it for example."
are there any other applications for this except re-indexing?
Also, is it known, how internally the scrolling is implemented, i.e. is it
efficient in transferring to the client of only what is needed?

> There are possibly ways to improve collections of "deep paging" by passing
> Solr/Lucene more information about the last page of results seen, thereby
> saving priority queue operations. See LUCENE-2215.
> There may also be better options for retrieving large numbers of rows at a
> time that are worth exploring. LUCENE-2127.
