[jira] [Created] (OAK-9361) PrefetchIterator#getSize() may access the internal iterator unnecessarily

Manfred Baedke created OAK-9361:
-----------------------------------

             Summary: PrefetchIterator#getSize() may access the internal iterator unnecessarily
                 Key: OAK-9361
                 URL: https://issues.apache.org/jira/browse/OAK-9361
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: jcr
            Reporter: Manfred Baedke
            Assignee: Manfred Baedke


If fastSize is enabled and minPrefetch is 0, there is no need to check the internal iterator for the availability of a next value, which can be expensive in edge cases (e.g. if the result is very large but the caller actually doesn't have access rights to any of the entries).
