Hi Spark dev folks,

First of all kudos on this new Data Source v2, API looks simple and it makes easy to develop a new data source and use it.

With my current work, I am trying to implement a new data source V2 writer with Spark 2.3 and I was wondering how I will get the info about partition by columns. I see that it has been passed to Data Source V1 from DataFrameWriter but not for V2.


Thanks,
Aakash
