What is a characteristic of action nodes that are unchained?

The characteristic of action nodes that are unchained is that they execute without dependencies. When action nodes are unchained, they operate independently from one another, meaning that the execution of one action does not rely on the completion of another. This allows for greater flexibility in workflows, as multiple unchained nodes can run simultaneously or be triggered at different times, contributing to more efficient process execution.

In contrast, chained nodes imply that there are dependencies between them, meaning that one node must complete before the next one can start. Options referring to execution times, memory usage, or the ability to execute multiple times do not accurately describe what it means for action nodes to be unchained in this specific context. They focus more on the conditions that affect how nodes interact rather than the independence that defines unchained action nodes.
