I noticed in the app that these queries were slowwww! I was able to track it down to a bad query plan, as we explain in the comment. I searched online for "mysql query performance filter on one join table sort by another", and was surprised to find this answer suggest a subquery, which I've often been told to expect to be slower compared to joins? But it certainly worked in this case! https://stackoverflow.com/questions/35679693/mysql-optimize-join-with-filter-and-order-on-different-tables |
