View Source Reactor

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.

Installation

The package can be installed by adding reactor to your list of dependencies in mix.exs:

def deps do
  [
    {:reactor, "~> 0.8.1"}
  ]
end

Documentation for the latest release will be available on hexdocs and for the main branch.
