Recipe-Walkthrough

The recipe walkthrough has two large functionalities. The first one is the initialization of a recipe. When a recipe along with all of it’s steps are triggers are sent to this service, it will first store this data in memory and also initialize the current state. The state has data about what step we are currently on. After storing this data, the triggers and the actions for the first step will then be sent over and registered in the trigger queue.

The other functionality of this service is to either change the current step or the current recipe. If the action is to change the step (i.e. an action from a trigger is trying to increment to the next step) or recipe, both will first will ensure that all triggers for the currently active step have been removed from the trigger queue. If it a new step, the new step will be initialized. If the step is to change recipes, it will now enter the initialize recipe workflow.
