I'm not exactly sure which part of the change was the issue, but it resulted in an explosion of database connections, ultimately exhausting the database. It likely has to do with the context manager not exiting as expected and the session not being closed.
I've reverted this because I don't think it's currently required, but was opportunistic in nature (it was included in a PR with other unrelated optimizations).
