D1user2412-d1-failed-import-writes

user2412: failed D1 imports that hit the 30s timeout still billed 109M writes, $59.

Community user user2412 says importing the CBDB biographical database (about 80 tables, 9.5 million rows, 375 indexes) into D1 with Wrangler repeatedly hit the 30-second timeout, and each failed attempt still consumed billed writes even though the transactions rolled back. The account was charged for 109 million writes against a 50 million free tier, so 59 million writes were billed at $1 per million, $59. The author argues the platform's timeout limit is being turned into user cost, and later posts billing case 01780096.
