Comment 20 for bug 1918145

Rodolfo, yes, we have that commit/PR -- specifically, we're now on a very recent Ussuri and still have slow queries without applying workarounds to the code.

Although c#9 and c#10 may be confusing, I can absolutely attest that working around that saved us a bunch of heartache at scale - we saw OpenStack API calls that were running for upwards of one minute or more get cut down to 100s of milliseconds.

I am tied up early this week triaging some other issues, but ack your request to add an index and report back.
