Multi-app workflows다중 앱 워크플로

One durable workflow dispatches activities to services with different app IDs.

···

Durable Object facets동적 앱별 저장소 분리

Give each dynamically loaded app its own SQLite storage.

···

Sharded workflow control plane분산 워크플로 제어면

Distribute coordination across workflow shards to scale concurrent executions.

Task queue priority and fairness작업 큐 우선순위와 공정성

Run urgent tasks sooner while preventing one tenant from monopolizing shared workers.

Cloudflare Dynamic Workflows, introduced in 2026, let a loader select tenant code by ID and connect it to a durable workflow engine. Even if a step resumes hours later, dispatch returns to the appropriate tenant code without keeping idle code running.

The demo sends the same start request through different stages for tenants A and B. Platforms running dynamic code still need explicit isolation, versioning, and authorization.

When to use

Consider it for a multi-tenant platform that executes different automation code per customer.
