The "Condition" is a one-of-a-kind task having two outputs instead of one.

It allows you to branch your pipelines and dynamically execute one part of it if the condition result is true and another one if it is false.

As same as the "" the "Condition" can use like SUM(), AVG() and other aggregating functions and operations like +,-,==, !=,<,>. etc. The full list can be found .

The result of it can be compared with a desired value.

For example:

In addition to that, you can execute several tasks depending on the condition is true or false:

Or build more complicated branched and nested conditions:

🚡
Aggregator
mathematical functions
here
If list is not empty
If average amount is equal to the last amount
Or even a single field value can be used
