Out of interest, what happens if you’ve added some custom indexes to your slurmdbd?  I’ve had slow query log running on ours, and added some custom indexes for certain cases, which has made sacct quite a lot faster for certain queries, but I worry about whether I’ve created a land-mine for future upgrades which include schema changes…. I can always delete the indexes as part of my SOP of course, and re-create them afterwards

That's only an issue when doing a major Slurm upgrade from (eg) 23.11 to
24.05 or 24.11.

For a minor upgrade like you're doing you should be able to mix and
match versions (though of course it's best to minimise it).

All the best,
Chris
