Limitless or big data runs in Newman/Postman runner


I want to run a collection which will be adding live data to my database (limitless run) or a collection which will add plenty of data to my database. I wrote those collections, its ready to use but there is a huge problem called MEMORY. Durning live mode collection or that which adds plenty of data to my database (it can run a few hours) my memory is filled in 100% and my computer stops working. I don’t understand why postman and newman keeps some data. Moreover, this data rapidly increases to the max size of my cache memory.

I wander if there is any possibility to stop storing data in Newman/Postman.
Because this makes my collections very limited to small amount of data and this is big problem for me.

Thanks for any kind of help/information.
