Workflow Execution and Data Flow
The order of workflow operation can be split into two concepts:
Workflow Execution
A workflow processes nodes in sequential order:
- Beginning at the root of the Node tree with an entry node.
- Every subsequent node in the chain is processed in order. The execution may take the path of another branch based on conditionals.
- The workflow ends either when it reaches an explicit exit node or when no more nodes are available in the chain.
Workflow Data Flow
Each node in a workflow has an input and output data type.
With this typed data system, even though nodes are processed sequentially, you do not need a direct line between two nodes in order to pass data from one to another. Instead, data can be referenced using dot notation of a node's alias and it's output alias:
$[node_alias].[output_alias]TIP
You can view the data type by clicking on a node and viewing the value within the parenthesis next to the name of the object.
