Delightful Durable Function Patterns

on YouTube ↗48m

" summary

Azure Durable Functions are shown as a code-first way to build stateful serverless workflows using client, orchestrator, activity and entity functions with Azure Storage event-sourced history; six concrete patterns are demonstrated: function chaining, fan-out/fan-in, async HTTP API, monitor, human interaction, and aggregator. Orchestrators replay deterministically (avoid DateTime/random/multi‑threading), the library supplies 202 + status URLs and durable timers, and the claim is that only the orchestrator’s lifecycle is billed while activities run independently—examples include a parallel lumpia factory and an approval-with-timeout demo.
