Hi, I'm doing some migration squashing, which was long overdue; so, I'm squashing dozens of migrations at once. Within these migrations, there are data migrations (RunPython operations) which, of course, stand as barriers to optimization. The operations have not been defined elidable -- because we are still on Django 1.8. So, after squashing, I go over the operations one by one, find that they are indeed elidable, and delete them. Which leaves me with a sub-optimized squashed migration.
This got me thinking, though, about our solution to the situation in general: If I were on Django 1.10, I could probably solve my problem by changing the original operations to elidable, and then running squashmigration again. But does this solve all cases? Wouldn't we like a way to take a hand-edited migration, squashed or otherwise, and optimize it? For the record, the optimizing command was suggested, under the name "resquash", by Piotr MaliĆski[1]. The suggestion didn't really get a lot of traction, and as mentioned, the "elidable" flag solves a big part of the problem, if not all of it. Thoughts? Thanks, Shai.
