What's the fastest way to pickle a pandas DataFrame?

Question

Which is better, using Pandas built-in method or pickle.dump?

The standard pickle method looks like this:

pickle.dump(my_dataframe, open(\'t         


        

Answer 1

Easy benchmark, right?

Not difference at all, in fact I expect that Pandas implements getstate so that calling pickle.dump(df) is actually the same as calling df.to_pickle().

If you search for example __getstate__ on the Pandas source code, you will find that it is implemented on several objects.
