We are really looking for serialization libraries that will work with pandas and scikit.

This stuff is really all over the place - PMML, Arrow, Dill, pickle.

Some stuff won't work with one or the other. I will actually pay for consistency versus performance.

There are way too many primitive serialization libraries. Surprisingly none for the higher order ML, etc stuff.

Give the kind of people behind Arrow, I would love wrapper that will use Arrow to do all of this...But doesn't matter at the end of the day.
