Reactor

Elixir CI License: MIT Hex version badge

Reactor is a dynamic, concurrent, dependency resolving saga orchestrator.

Woah. That's a lot. Let's break it down:

  • Saga orchestrator A saga is a way of providing transaction-like semantics across multiple distinct resources.
  • Dependency resolving reactor allows you to describe the dependencies between your saga steps using arguments which are converted into a DAG and used to compute execution order.
  • Concurrent unless otherwise specified reactor will run as many steps as possible concurrently whilst taking into account the results of the dependency resolution.
  • Dynamic whilst you can define a reactor statically using our awesome DSL, you can also build workflows dynamically - and even add steps while the reactor is running.
