Edge

An edge is a connection between two nodes in a workflow graph. It is a directed connection, meaning that it has a source node and a target node. The source node is the node from which the edge originates, while the target node is the node to which the edge points.

Edges are used to define the sequence of execution in a workflow graph. The target node of an edge is executed only after the source node has completed execution. This allows for the creation of complex workflows that can't be adequately represented in a linear sequence.
