Parallel state allows you to process multiple states in parallel and perform simultaneous executions.

Let us see how to configure the Parallel state in Builder View and Code View.

Builder View

In order to execute states in parallel, you must configure them as paths in the Parallel state.

1. In Builder View, drag and drop the Parallel state from the left pane into your Circuit or click the required Parallel state in your Circuit.
2. Under the configurations tab, update the common state field attributes and click Add Path, to add parallel states.
3. Under Add Path section, in the Name field, provide a unique name for the path and in Start At field provide the state that needs to act as the root or starting point for the path.
   
4. In the Input/Output section, you can configure the required paths for a parallel state as discussed in Input & output processing section.

      

If any path fails, either by an unhandled error or by transitioning to a failure state, the entire Parallel state is considered to have failed and all its paths are stopped. If the error is not handled by the Parallel state itself, the Circuit terminates the execution with an error.

Code View

In Code View, along with the common fields, the paths are also defined with their unique name and root.

Parallel state example:

"Parallel IT Tasks - Employee Provisioning": {
    "type": "parallel",
    "next": "Onboarded Successfully",
    "paths": [
        {
            "name": "add_ad_user",
            "root": "Add User in AD"
        },
        {
            "name": "add_ad_group",
            "root": "Add User to AD Group"
        },
        {
            "name": "add_user_db",
            "root": "Add User in Legacy Database"
        },
        {
            "name": "add_asset",
            "root": "Asset Allocation"
        }
    ]
}
