ThingsBoard save an array sent from Python inside a JSON

Question

I've been trying for days to understand if ThingsBoard (TB) is capable of manipulating arrays. So far, I found out that one can not simply send an array from Python to a Device in TB directly. However, it is possible to send it if it is previously packed inside a JSON with an appropriate JSON key.

To my knowledge, the array can then be accessed through a function inside a RuleEngine which would parse the incoming data.

Before I try to write this function, I would like to know if the RuleEngine will require me to save the array value by value in the database, with each value having a different name or timestamp, or can I save the array directly inside one DataPoint, with one name and one timestamp for the entire array.

The array represents a 48h temperature prediction (calculated in Python), which I would like to update every hour while saving every previously predicted array. I am using requests library with HTTP API in TB.

Thank you in advance for your reply!
