Wes suggested to raise this feature request here again, after I wondered why pandas.read_feather is lacking a columns-parameter like the feather-format package has it.

You can read in only a subset of columns from a feather-file with e.g.:
df = feather.read_dataframe('df_test.feather', columns='b')

It would be really nice if pandas.read_feather also had this built in, so you don't have to install and import the feather-package just for that.
