Subject [jira] Commented: (DIRSTUDIO-312) Add count function

Alex Karasulu commented on DIRSTUDIO-312:
-----------------------------------------

Each server will probably implement such a  count function over a filter.  Just the subordinates
or descendant count is not enough IMHO.  For this reason I think we should be looking at a
search request control which makes the search request return immediately with a search response
control showing the number of entries that would be returned for the search.  The search would
not return any entry results.

Latest changes proposed for ApacheDS system indices allow for easily implementing the count
function as a control.  Scan count calculations are already performed so we can use this to
implement a count control on search instead of performing the search.

> We should add a count function that counts the children of an entry or the results of
a search. Currently when searching at least the DN and the object classes of an entry are
loaded and stored in memory. This is very memory intensive if one just wants to know the number
of children.
