Aggregator

The "Aggregator" is designed to transform an input dataset into one single variable.

To do that it uses mathematical functions like SUM(), AVG() and other aggregating functions.

In addition to the mathematical expression, you can also configure how you want the output variable to be called to access it in the next task.

In the following example, an aggregator calculates an average invoice amount in the input dataset and rounds it down to 2-digit precision. The result is available in the next task as {{ average_amount }}
