Cluster nodes#

Cluster nodes are node groups that work together to provide functionality in an n8n workflow. Instead of using a single node, you use a root node and one or more sub-nodes. This allows extensive configuration of node functionality.

Root nodes#

Each cluster starts with one root node.

Sub-nodes#

Each root node can have one or more sub-nodes attached to it.
