Thomas Mueller updated OAK-2926:
--------------------------------
Description:
When asking for the correct result size of a query, the complete result needs
to be read, so that access rights checks are made, and (unless the index is
known to be up-to-date, and can process all conditions) so that the existence
and all query conditions are checked.
Jackrabbit 2.x supports a fast way to get an estimate of the result size,
without doing access rights checks. See also JCR-3858.
Please note that according to the JCR API, NodeIterator.getSize() may return -1
(for "unknown"), and in Oak this is currently done if counting is slow. This
would also need to be disabled if a fast result size estimate is needed.
