Specification

The Distributed Async Await specification — protocols, definitions, and models for durable execution.

Protocols, definitions, and models

Distributed Async Await is a collection of protocols, sub-specifications (definitions), and models. This section is the canonical home for the formal specification — for working code that implements it, see the TypeScript, Python, and Rust SDKs.

The specification is structured into three parts:

  • Programming model — the intended structure of distributed programs and the developer interface.
  • Execution model — how distributed programs reliably make progress.
  • System model — the environment in which distributed programs exist, and a way of thinking about them.

A glossary defines the load-bearing terms.
