Deep dive in Durable Functions

" summary

Azure Durable Functions provide code-based workflow orchestration on Azure with fan-out/fan-in parallelism and long running steps by using a special orchestrator that serializes state to Azure Storage and then orchestrator sleeps to avoid billing. Practical limits include a consumption timeout of 5–10 minute timeout (premium ~30 minutes). Example: automation that rebuilds docs.microsoft.com session pages for ~300 sessions every 30 minutes runs ~30 minutes locally but ~2 minutes on Azure. Gotchas: avoid local files, keep serialization public (no internal setters), never await non‑context tasks, and manage task hub names when purging history.
