Deep dive into Azure Durable Functions

on YouTube ↗53m

" summary

Deep dive into how Durable Functions actually runs: the runtime replays orchestrators from an event-sourced history table and stores current status in an instances table, uses a task hub with blob leases to implement a distributed lock across a configurable number of control queues, and sends activity work via a shared work item queue. Coverage includes the default Azure Storage provider layout (tables, blobs, leases), Netherite’s Event Hubs + page blobs + Faster backend, the SQL provider built on stored procedures, service-bus transactional behavior, and the in‑memory emulator for testing.
