Feather efficiently stores pandas DataFrame objects on disk. It depends on the Apache Arrow for Python

pip install feather-format

pip users note: feather-format depends on pyarrow and may not be available on your platform via pip. If that does not work try conda-forge.

From conda-forge:

conda install feather-format -c conda-forge

Some features of pandas are not supported in Feather:

• Non-string column names
• Row indexes
• Object-type columns with non-homogeneous data
