Full-table scans on D1 produced $564.23 in usage for one cycle.
Community user need1026 says a hot-path query that full-scanned a large table without an index drove the May 13 to June 12, 2026 cycle to $564.23 of billable usage, almost all D1 Rows Read ($562.84). The author added the missing indexes on June 5 and asks for a one-time credit before the invoice is finalized.
