   Thanks @potiuk  and @mik-laj for the review. I updated the PR according to your comments.
   
   Also, I noticed that doing `TR.__table__.delete().where(...)` seems to be slightly faster than what I was doing with `session.query(...).filter(...).delete()` by a small margin. So I changed the PR to use it instead.
