Using asynchronous workflows

A workflow executes its elements along its path one after another. Using asynchronous workflow execution, we can change this behavior and actually execute workflows in parallel.

Getting ready

We will need to build a new workflow.

For the first example, we will reuse the sleep workflow as well as the getNow action we created in the recipe Waiting tasks in this chapter. (06.04.01 Sleep and the com.packtpub.Orchestrator-Cookbook2ndEdition.helpers module in the example pack).

How to do it...

We will see two examples to demonstrate the asynchronous feature.

The first example

Here are some basics:

1. Create a new workflow and create the following variables:

   Name	Type	Section	Use
   sleepTime	Number	IN	It defines the time the workflow should sleep
   wfToken	WorkflowToken	Attribute	The workflow token of the asynchronous workflow

2. Drag an Asynchronous workflow task into the schema.

3. When prompted, enter the name of the sleep workflow we have created in the recipe...
