Scott Stults commented on SOLR-1726:
------------------------------------
Dmitry, I think "scrolling" would help in the case of Hadoop integration, such
as pulling a few hundred thousand docs based off of a query to the local node
so that you can do an aggregated calculation with Pig or M/R.

> 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.
