RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:
lmdb and lmdb-devel are needed to build and run kf5-baloo

If kf5-baloo isn't able to be rebuilt, it will affect:

 * dolphin
 * gwenview
 * plasma-desktop
 * plasma-mediacenter
 * plasma-milou
 * plasma-workspace

Basically, withouth lmdb and lmdb-devel, KDE Plasma Desktop cannot be in epel9.

Version-Release number of selected component (if applicable):
lmdb-0.9.29-3.el9

This is done for current composes.

rhel9 lmdb-libs-0.9.29-3.el9.i686
rhel9 lmdb-libs-0.9.29-3.el9.x86_64

I have verified that I can see, and build with lmdb and lmdb-devel from CentOS Stream 9.
This allows me to build my packages in epel9.
Thank you very much.
I don't know what else needs to be done for this ticket, but for me it can be closed if you want.

I'm not sure why this wasn't closed.  
lmdb lmdb-libs and lmdb-devel are available in RHEL 9.1
