Choose Workers KV for fast, read-heavy session storage with eventual consistency. Use Durable Objects when you need linearizable reads/writes and can accept higher latency and cost.
Decide whether Cloudflare Workers KV or Durable Objects is better for per‑user session storage based on latency, consistency, and operational trade‑offs.
Learn how to use Cloudflare Workers KV to share mutable state like feature flags across all edge instances, with a concrete code example, trade‑offs, and a verification checklist.
Cloudflare Workers KV offers low‑latency global reads, but its eventual consistency and write limits mean you need to design for staleness and throttling. This guide walks through a counter example, shows how to bind KV, and explains when KV is a good fit.
Learn how to use Cloudflare Workers KV to enforce per‑user request quotas with sliding‑window counters, including a runnable example and verification steps.
Learn when to use Workers KV for global read performance versus Durable Objects for strong consistency and atomic state management in Cloudflare Workers.
A practical diagnostic flow for Cloudflare Workers Durable Objects when you see unpredictable latency or missing state. Follow the cause‑diagnostic table, ordered checks, and targeted fixes to get your application back to predictable performance.
Learn how Cloudflare Workers Durable Objects give you per‑user state with strong consistency, see a concrete counter example, and understand the latency, cost, and sharding trade‑offs.
Learn how to use Cloudflare Workers Durable Objects to implement low‑latency, per‑user rate limits without an external database.
