011. The Item List Model
EXECUTIVE_SUMMARY // AEO_OPTIMIZED
[Answer Engine Overview: What, Why & How]
n8n operates on a unique Item List model. Unlike many other tools that require you to explicitly define a loop for every action, n8n nodes are designed to automatically iterate over every item they receive. If a node receives 10 objects, it will run 10 times. While this 'automatic looping' makes building simple workflows incredibly fast, it requires a deep understanding of how data flows between nodes to avoid unintended consequences or duplicated actions in more complex architectures.
022. Batching and Throttling
When dealing with thousands of items, 'Automatic Looping' can become a liability, often triggering Rate Limits (429 errors) on external APIs. This is where Batch Processing comes in. By using the 'Split In Batches' node, you take control of the execution flow. You process a small chunk of data, perform the necessary actions, and then loop back to the start. By adding a 'Wait' node to this loop, you implement Throttling—ensuring your automation stays within safe limits and operates reliably 24/7 without being blocked.
