Iteration Node (Realtime)

The Iteration Node is essentially an array processor. In the Realtime Canvas, you map a specific array payload (like a JSON list of products), and the Iteration Node feeds them one-by-one into a subsequent block (like an Agent Node).

Streaming Data Sequences

When an external system Enqueues a real-time call, the starting payload frequently contains large dataset bounds (e.g., $5$ open tickets assigned to a caller).

The Iteration Node traverses this mapped list invisibly in the background, firing conversational summaries down the WebSocket. It guarantees that the caller will hear the sequence properly ordered without the LLM getting confused about multiple concurrent documents.

[!NOTE] The Iteration Node operates locally in memory. It causes absolute zero audio delays to the caller between iterations, provided the downstream components do not pause.
