Subject [jira] [Commented] (DIRSERVER-2162) Searcing for users using ObjectClass=person takes long
Date Thu, 11 Aug 2016 08:19:21 GMT

    [ https://issues.apache.org/jira/browse/DIRSERVER-2162?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15416734#comment-15416734
] 

Emmanuel Lecharny commented on DIRSERVER-2162:
----------------------------------------------

There is indeed a problem : we pull the full data from the backend when doing a search with
{{ObjectClass=person)}}, while we should pull a reference to a sub-btree. This is absolutely
wrong, and that will impact the addition/update operations performances greatly.

>             Project: Directory ApacheDS

>    Affects Versions: 2.0.0-M20

> When we do the below query the result takes long. Around 10-50 seconds.
> Search base: ou=users,dc=xxx,dc=fi
> Filter (&(cn=*USERNAME*)(objectClass=person))
> Scope: Subtree
> However the below query returns the result immediately
> Search base: ou=users,dc=xxx,dc=fi
> Filter (&(cn=*USERNAME*)(objectClass=*))
> Scope: Subtree
> Looking at the Partition settings it has Indexed attributes ObjectClass and cn.
> First both queries took long. Then we added cn to the index and rebooted apacheDS and
the second query got fast.
> It seems like a bug that using ObjectClass in the query makes it slow all tough it is
in the index.
> It seems something similar was reported before DIRSERVER-2048, but it says it's fixed
in M20 which we are using.
