I'm trying to import nodes from a Drupal 7 database to a brand new Drupal 8 one using the Feeds module.
I'v imported stuff and then deleted it (because I'm testing at the moment the best way to do it). I keep deleting nodes, but I've noticed that the revision tables are full of stuff.
Currently there is no node in the site, but the revision tables are occupying 50MB already.
Is it safe to empty all those tables?
