Thanks for the info William and Thierry, this all makes sense. We'll start testing in the coming weeks and see how it goes. -morgan > On May 19, 2022, at 03:25, Thierry Bordaz <tbordaz@xxxxxxxxxx> wrote: > > > On 5/19/22 1:51 AM, William Brown wrote: >> >>> On 19 May 2022, at 00:48, Morgan Jones <morgan@xxxxxxxxxxxxxxx> wrote: >>> >>> Hello Everyone, >>> >>> We are merging our student directory (about 200,000 entries) into our existing employee directory (about 25,000 entries). >>> >>> They're a pair of multi-master replicas on virtual hardware that can easily be expanded if needed though hardware performance hasn't been an issue. >>> >>> Does this justify creating separate database for students?

The benefit to extra databases is "improved write performance" generally speaking.

Just a comment if you decide to merge the students entries into the employee directory. Either you will have to ADD 200K students entries into your existing directory and it will take several hours. Either you will use import (e.g. merge employee/students ldifs and reimport), that will require a reinit of the topology. The second option would be the fastest as import + reinit of a db with 225K entries should be fast. >> >> >>> We're still on CentOS 7 for the time being: >>> [root@prdds21 morgan]# rpm -qa|grep 389 >>> 389-admin-1.1.46-4.el7.x86_64 >>> 389-console-1.1.19-6.el7.noarch >>> 389-dsgw-1.1.11-5.el7.x86_64 >>> 389-admin-console-1.1.12-1.el7.noarch >>> 389-ds-1.2.2-6.el7.noarch >>> 389-ds-base-libs-1.3.10.2-13.el7_9.x86_64 >>> 389-ds-base-1.3.10.2-13.el7_9.x86_64 >>> 389-adminutil-1.1.22-2.el7.x86_64 >>> 389-admin-console-doc-1.1.12-1.el7.noarch >>> 389-ds-console-doc-1.2.16-1.el7.noarch >>> 389-ds-console-1.2.16-1.el7.noarch >>> [root@prdds21 morgan]# >>> >>> thank you, >>> >>> -morgan >>> >>> >>> >>> _______________________________________________ >>> 389-users mailing list -- 389-users@xxxxxxxxxxxxxxxxxxxxxxx >>> To unsubscribe send an email to 389-users-leave@xxxxxxxxxxxxxxxxxxxxxxx >>> Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ >>> List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines >>> List Archives: https://lists.fedoraproject.org/archives/list/389-users@xxxxxxxxxxxxxxxxxxxxxxx >>> Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure >> -- >> Sincerely, >> >> William Brown >> >> Senior Software Engineer, >> Identity and Access Management >> SUSE Labs, Australia >> _______________________________________________ >> 389-users mailing list -- 389-users@xxxxxxxxxxxxxxxxxxxxxxx >> To unsubscribe send an email to 389-users-leave@xxxxxxxxxxxxxxxxxxxxxxx >> Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ >> List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines >> List Archives: https://lists.fedoraproject.org/archives/list/389-users@xxxxxxxxxxxxxxxxxxxxxxx >> Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure > _______________________________________________ > 389-users mailing list -- 389-users@xxxxxxxxxxxxxxxxxxxxxxx > To unsubscribe send an email to 389-users-leave@xxxxxxxxxxxxxxxxxxxxxxx > Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ > List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines > List Archives: https://lists.fedoraproject.org/archives/list/389-users@xxxxxxxxxxxxxxxxxxxxxxx > Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure _______________________________________________ 389-users mailing list -- 389-users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to 389-users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/389-users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
