Introducing on-demand profiling: Cloudflare production examples

Dominik Picheta introduces on-demand CPU and memory profiling for Workers and Durable Objects, sharing Cloudflare examples of removing duplicate work and unnecessary allocation paths.

CloudPrinters.sa: an auth refresh-token bug drove about 2 billion D1 writes and a ~$2,078 charge.

Community user salman1 says D1 normally costs CloudPrinters.sa nothing, but over the August 16 to September 15, 2026 cycle an auth bug rewrote one account's entire refresh-token history every time a stale token was retried, generating roughly 2 billion D1 writes. He says the revoke logic and retry loop were fixed and that a billing ticket requests a courtesy credit for the D1 write overage of about $2,078.

Workers

RetainDB: a reported $36k bill from a queue loop with 81 users.

Reddit user alameenswe, building RetainDB on Workers, KV, Durable Objects and Queues, reports a Cloudflare bill of about $36k for one month with 81 users; the post body says $35,000. He attributes it to a queue consumer that re-queued async writes, 12 unbatched Durable Object writes per memory write and a kv.list() authentication fallback.

A missing index on a D1 DELETE read about 4 trillion rows, a $4,114.97 charge.

Community user user11226 says a missing database index made a DELETE operation repeatedly scan the table, generating about 4.03 trillion D1 rows read in the billing period and an unexpected $4,114.97 bill on what they understood to be a $5-a-month subscription. In follow-ups they accept they should have configured billing alerts, say Cloudflare successfully challenged their chargeback while the urgent billing case took more than three weeks to get a response, and ask for someone to review the circumstances.
