[jira] [Commented] (DIRSERVER-2129) Add the number of descendant and the number of children to entries

["Emmanuel Lecharny (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DIRSERVER-2129?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15181673#comment-15181673 ] 

Emmanuel Lecharny commented on DIRSERVER-2129:
----------------------------------------------

A better solution : add a method in the BtreePartition that returns those two values. It will be invoked in the {{OperationalIntecreptor}} if those values are requested. That will not impact any other code, and it will cost only for the requests looking for those values.

> We do have this information in the database, associated with the ParentIdAndRdn, it would be interesting to add them as operational attributes to any entry pulled from the database.
> It will require a bit of refactoring of the {{AbstractBtreePartition.buildEntryDn()}} method, because we cache the DN to avoid pulling the information everytime.
> Another possibility is to get those 2 values only if required.
