Overview

Iterate over an Array received on the input, wait a feedback from all the sent elements before send an output on the second output

Parallel Iterator

This node have 1 input and 2 outputs, the upper output is where is sent each element of the Array, the lower output is where is sent the output after all elements of the Array are processed.

Every element of the Array is sent as payload.

While the node is iterating over the Array he preserve the values of the properties that aren't payload.

The node have the following properties :

Iterate over msg.

Is the property that contains the Array that you want to iterate, you can use a dot for access to deeper properties Example :

payload.response.items

Output processed data

The data from each feedback is stored in an Array that is at the end passed as payload.

Recursive

If this checkbox is checked then the node will check while iterating if the input is an Array, in positive case the node will start iterating over the new input, and after finishing the new iterations then continues with the previous input.

Store id in the message

If this checkbox is checked then the node stores an identifier of the flow in the msg. If you have simultaneous flows flowing in this node at the same time, you need to check this property. In case you have only one flow at a time it's better to not use this property because if is used your feedback needs to have the property stored in the msg.
