Feather: A Fast On-Disk Format for Data Frames for R and Python
HDF5 is supported by many languages including C, C++, R, and Python. It has compression built in. It can read slices easily. It is battle-tested, stable, and used in production for many years by thousands of people. Pandas even has integrated support for DataFrames stored in HDF5.<p>What's the advantage of Feather over HDF5? Couldn't the Feather libraries be written with the same API but HDF5 as the storage format, if the Feather API is preferable?
