Web1 day ago · Vaex convert csv to feather instead of hdf5. Does vaex provide a way to convert .csv files to .feather format? I have looked through documentation and examples and it appears to only allows to convert to .hdf5 format. I see that the dataframe has a .to_arrow () function but that look like it only converts between different array types. I am processing a huge dataset (50 million rows) in CSV. I am trying to slice it and save it as Feather Format in order to save some memory while loading the feather format later. As a workaround, I loaded the data in chunks as CSV file and later merged it into one data frame. This is what I have tried so far: df[2000000:4000000].to_feather('name')
