Changed

The Changed node determines whether the incoming dataset has changed compared to the previously processed version. It uses an internal cache to compare the current data with the last stored state and controls whether the dataflow continues.

This node has no configuration options.

When to use it

The Changed node is typically used to prevent downstream processing when the incoming data is identical to the previous run. If changes are detected, the dataflow continues; if no changes are detected, the dataflow is stopped.

Tips

• Place this node early in the dataflow to avoid unnecessary processing.
• Use for update-only or incremental dataflows.
• Ensure consistent row ordering in the input data.
