[Cadence](https://github.com/uber/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.
