Cadence is a distributed, scalable, durable, and highly available orchestration engine we developed at Uber Engineering to execute asynchronous long-running business logic in a scalable and resilient way.

cadence-client is the framework for authoring workflows and activities in Java.

If you are authoring in Go, seeGo Cadence Client.

For samples, seeSamples for the Java Cadence client.

Run Cadence Server using Docker Compose:

If this does not work, see instructions for running the Cadence Server athttps://github.com/uber/cadence/blob/master/README.md.
