we should probably run it in the morning after billing.

Approved but those 53'34' minutes worry me... maybe we should consider releasing the DB (sleep(0.5)) after each batch so other processes can update it in the meantime 🤔 or maybe I am being too paranoic and it is fine 😄 but in that case, we should run it when there isn't much traffic 🤔
