Cadence: Durable Workflow Orchestration

by Shriira Press

A practical, in-depth guide to Cadence, the fault-tolerant workflow orchestration engine (from Uber) that pioneered durable execution. Learn how Cadence makes reliable long-running processes easy: the durable execution problem, the server and worker architecture, workflows and activities, event history and determinism (replay), timers, signals and queries, reliability (retries, timeouts, heartbeats, sagas), versioning and replay testing, and operating Cadence at scale.
