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.
