Developer Tejas Kumar criticized Cloudflare's D1 database after three months in production: 3% of reads take 3-10 seconds while the same SQL runs in 1ms on an idle database, "overloaded" errors appear at just a few hundred queries per second, and he's seen minute-long freezes. He hopes the product improves; the post is drawing attention to D1's production reliability.
