Subject [jira] Resolved: (JCR-2710) Add support for large number of users in a group
Date Tue, 24 Aug 2010 12:14:17 GMT

     [ https://issues.apache.org/jira/browse/JCR-2710?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Michael Dürig resolved JCR-2710.

    Fix Version/s: 2.2.0
       Resolution: Fixed

This is basically fixed now. A possible improvement is to make group membership collection
lazy. I'll create a separate issue for that.

> In the current implementation there are several factors which limit the number of users
in a group:
> - group membership is recorded in a multi valued property which does not scale well
> - members of groups are collected eagerly which does not scale well
> I propose to add complementary support for recording group membership in a node structure
to the current solution. That node structure would - similar to users and groups - add intermediate
nodes when a group reaches a certain threshold on the number of its users.
