-----------------------------------
Summary: 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.
