What people warn about
Each mark is one comment
Very expensive at non-trivial scale
“KV is so expensive that it's barely usable, and like R2, is very slow.”
Comment from 3 Nov 2025 in “Oxy is Cloudflare's Rust-based next generation proxy framework (2023)” “KV is super expensive - once you're operating at non-trivial scale”
Comment from 3 Nov 2025 in “Oxy is Cloudflare's Rust-based next generation proxy framework (2023)” “Cloudflare KV is so extremely ridiculously absurdly expensive”
Comment from 25 Jun 2026 in “Cloudflare launched self-managed OAuth for all” Slow writes and high latency
“writes are way too slow for database-ish use and "eventually consistent" isn't what you want for state that is changing often”
Comment from 25 Jun 2026 in “Cloudflare launched self-managed OAuth for all” “KV checks/DB queries through their services can be double-to-triple digit ms latencies”
Comment from 11 Nov 2025 in “Head in the Zed Cloud” “KV is so expensive that it's barely usable, and like R2, is very slow.”
Comment from 3 Nov 2025 in “Oxy is Cloudflare's Rust-based next generation proxy framework (2023)” Locked in, hard to migrate away
“It requires a rewrite and to migrate production systems away from it.”
Comment from 10 Oct 2026 in “Cloudflare acquires Deno” “those locked-in things (KV, D1, etc.) always made it hard to switch.”
Comment from 1 Jan 2026 in “OpenWorkers: Self-Hosted Cloudflare Workers in Rust” “you can't run KV or Queues”
Comment from 9 Oct 2026 in “Cloudflare acquires Deno”
