This takes ownership of the DataFrame so that drop is called earlier. Does not check if schema is correct
Concat the DataFrames to a single DataFrame.
Given two datatypes, determine the supertype that both types can safely be cast to
Simple wrapper to parallelize functions that can be divided over threads aggregated and finally aggregated in the main thread. This can be done for sum, min, max, etc.
