Worker Previews auto-provisions isolated Durable Objects and containers per preview
dinasaur_404 · x · 2026-09-22
Worker Previews automatically provisions a separate Durable Objects namespace/storage and container app/instances for each preview, so state changes, migrations, sessions, and concurrent tests stay scoped. KV, D1, R2, and queues bind by id/name—sharing means shared data; bind distinct resources to isolate.
