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

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

• Saga orchestrator Asaga is a way of providingtransaction-like semantics across multiple distinct resources.
• Dependency resolving reactor allows you to describe the dependenciesbetween your saga steps usingarguments which are converted into aDAG and used to compute execution order.
• Concurrent unless otherwise specified reactor will run as many steps aspossible concurrently whilst taking into account the results of the dependencyresolution.
• Dynamic whilst you can define a reactor statically using our awesome DSL,you can also build workflows dynamically - and even add steps while thereactor is running.

Thanks toAlembic Pty Ltd for sponsoring a portion ofthis project's development.

Reactor contains an igniter installer, so if you have igniter installed already you can runmix igniter.install reactor to add Reactor to your app.

The package can be installed by addingreactor to your list of dependencies inmix.exs:

defdepsdo[{:reactor,"~> 0.17.0"}]end
