Node

A node in a chain can be a workflow or another chain. It is a workflow if it has a workflow_id, and a chain if it has a chain_id.

A node can have multiple children, and it can have multiple parents. It is a tree structure, but it is not a binary tree.

You can define the behavior to handle logic better.

​​ Parallel

In Parallel mode, the node will run all children at the same time. It will wait for all children to finish before it finishes. The next element in the node will receive an array of results from all children.

​​ Sequential

In Sequential mode, the node will run all children one by one. It will wait for the first child to finish before it runs the second child.
