-----------------------------------------------------
i would add this extension to the Jackrabbit API such that JCR/Jackrabbit API
consumers can make use of it; thus moving this issue to jcr-commons

> New method RangeIterator.getSize(int max)
> -----------------------------------------
>
> Key: OAK-1930
> URL: https://issues.apache.org/jira/browse/OAK-1930
> Project: Jackrabbit Oak
> Issue Type: New Feature
> Components: core, jcr, query
> Affects Versions: 1.0
> Reporter: Thomas Mueller
> Assignee: Thomas Mueller
> Fix For: 1.1
>
>
> The method RangeIterator.getSize() is part of the JCR API, and returns the
> number of items, but can also return -1 if not known.
> Currently, Oak doesn't return -1, but counts the items. This is slow
> (potentially very slow) if there are many items, for example, in a query
> result.
> I propose to add a new method RangeIterator.getSize(long max) that limits
> counting the entries. That way, an application can use a reasonable limit,
> and Oak doesn't need to count.
