PR Summary
This PR optimizes document tag deletion performance and modifies email header handling, with key changes focused on query efficiency and email configuration.
- Improved orphan tag deletion in
/backend/onyx/db/tag.pyby replacing outer join/group by with a more efficient NOT EXISTS subquery - Added conditional 'From' header check in
/backend/onyx/auth/email_utils.pythat needs review as missing headers could cause email delivery failures - Query optimization removes dependency on SQLAlchemy's
funcmodule while maintaining correct tag identification

There was a problem hiding this comment.
logic: Removing the 'From' header when mail_from is None will cause email delivery failures. The 'From' header is required by SMTP. Should use EMAIL_FROM as fallback instead.
Suggested change
| if mail_from: | |
| msg["From"] = mail_from | |
| msg["From"] = mail_from or EMAIL_FROM |
