n8n Made Crystal Clear · chapter 2: How n8n Thinks: Workflows, Nodes, Items

The items pipeline, the anchor schema of this book

Figure 2.1 draws the whole thing in one picture: a trigger emitting three items, two nodes transforming the array, and one item's lineage traced from end to end. Later chapters point back at it constantly, so it is worth a slow look now.

Figure 2.1: The items pipeline, the anchor schema of this book. A trigger emits an array of three items. Every connection carries that array, never a bare record. Each node runs its configured operation once per item and outputs new items. The highlighted item 2 keeps its identity the whole way and links back, step by step, to the item that produced it.
