D1ken7-d1-failed-import-writes

D1 import failures reset the database and inflated writes to about 550 million rows.

ken7 reports migrating a read-heavy site to Workers with D1, then repeated internal D1 failures that reset the instance and forced full re-imports. The author says about 550,456,381 rows written on the invoice reflect failed import retries rather than production usage, and requests a waiver or credit. No dollar amount is given.
