Description
Currently playing with Polars and noticing that we don't support streaming which is quite nice for larger than memory datasets.
Note I'm just opening this as a trigger for discussion, I realize this is not yet done and cannot promise I will continue on this since this was just me playing around on the weekend. But hoping I get to play more and bring this into our pipeline (and thus here) :)
Development notes
Updated to the latest features of polars which includes streaming=True and leaving the option to the user to do partitioned writing using rust based parquet support
