A nested loop over priority tiers becomes the scheduler when every yield* is a durable Resonate checkpoint.
Process a batch of jobs in strict priority-tier order with up to 2 jobs running concurrently per tier. Each job is a durable checkpoint, so a mid-batch crash only retries the failing job — completed higher-priority jobs are not re-run.
How the fan-out / fan-in pattern collapses to four `yield ctx.rfi(...)` calls plus four `yield <handle>` fan-in points when every branch is a durable promise.
Notify a customer over email, SMS, Slack, and push in parallel. Each channel is an independent durable checkpoint, so a retry of one branch does not re-send the others.
How the fan-out / fan-in pattern collapses to four ctx.beginRun calls plus four yields when every branch is a durable promise.
Notify a customer over email, SMS, Slack, and push in parallel. Each channel is an independent durable checkpoint, so a retry of one branch does not re-send the others.
How the same recursive fan-out / fan-in workflow runs across six deployment shapes in three languages.
A recursive LLM agent that decomposes a topic into subtopics and dispatches a fresh durable workflow per subtopic, with six sibling variants spanning plain Node, Cloudflare Workers, Google Cloud Functions, Supabase Edge Functions, Python, and Rust.
How `ctx.run(...).spawn()` turns parallel work items into individually durable promises that survive process crashes.
Run several work items in parallel and collect their results, while keeping per-item progress durable across crashes. Each spawned task is its own durable promise, so a restart only re-executes items that had not completed.
How fan-out / fan-in over an AI-provider call collapses to two for-loops when each branch is a Resonate durable promise.
Generate multiple style variations of an image prompt in parallel, with per-branch crash recovery. Each generator call is a durable checkpoint; a failed call retries independently while the others continue.
