When a Cloudflare Worker needs mutable state, pick the right storage: KV for global, eventually consistent caching; Durable Objects for strong consistency, low‑latency per‑instance state. This guide compares options, explains trade‑offs, and shows a concrete example with validation steps.
When Durable Objects lose state, lag, or lose updates, the culprit is often a mis‑configured key, cold start, or race condition. This guide walks through common symptoms, ordered checks, quick fixes, and escalation steps.
Learn how to build a stateful counter with Cloudflare Workers Durable Objects, see the exact code, understand size and concurrency limits, and avoid common pitfalls.
A counter in a Worker's memory doesn't add up across locations. Here's how Durable Objects serialize per-tenant state, with a worked limiter and its limits.
A decision guide for choosing between Cloudflare Workers KV, Durable Objects, and D1 based on consistency, scaling, and access patterns, with a concrete validation example.
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.
