-----------------------------------------
Component/s: ldap
backend
> We don't have to update the RDN index up to the top when moving an entry
> ------------------------------------------------------------------------
>
> Key: DIRSERVER-2153
> URL: https://issues.apache.org/jira/browse/DIRSERVER-2153
> Project: Directory ApacheDS
> Issue Type: Improvement
> Components: backend, ldap
> Affects Versions: 2.0.0-M21
> Reporter: Emmanuel Lecharny
> Priority: Major
> Fix For: 2.0.0.AM26
>
>
> When we move an entry, we update all the ascendants up to the root, in order
> to update the number of descendants.
> We can save us a few updates by stopping when we met the common ascendant,
> because it will have the same descendant number.
> For instance, moving an entry from A/B/C/D/xxx to A/B/E/F/xxx will decrement
> the {{nbSubordinate}} counter for C and D, increment it for E and F, but for
> B, it will remain the same.
> Doing so, in this very example, we would save 4 updates, dividing by 2 the
> number of updates.
