We store the group deletion schedule in a separate table called [`group_deletion_schedules`](https://gitlab.com/gitlab-org/gitlab/-/blob/810aa9b753b76de360dbc31603f6ad660bb17d34/db/structure.sql?page=12#L11517) but we store the same info for projects in the projects table itself. To reduce the table width and improve performance, we should move the following scheduled project deletion-related columns to another table called `namespace_deletion_schedules` along with the required index and foreign keys: ```sql marked_for_deletion_at date, marked_for_deletion_by_user_id bigint, ```
