Could you define too long, and what problems it caused please? We're looking at upgrading Slurm to from 2.6 to 14.03 shortly and I believe that's when those extra indexes appear. We've got about 14 million rows across the various *_job_table and *_step_table. However, on our Percona Cluster (i.e. MySQL Galera) DB servers adding a multi-column index to an 8+ million row table in another database took just a few seconds.
