Dear all,
I would like to know about the nature of Orion. I have read that it does not
have a persistence system by default. I would like to implement an Orion that
stores sensor data from different sensors that are sending data continuously.
However, I would like to save the historical data, not to overwrite it. Is
there a simple way to not remove these "old" historical records?

Thank you very much.
