🖥 zarr - Python library for implementing compressed N-dimensional arrays

- pip install zarr

Zarr provides classes and functions for working with N-dimensional arrays, which behave like #NumPy arrays, but the data is divided into chunks and each chunk is compressed. If anyone is familiar with HDF5, Zarr arrays provide similar functionality, but they are more convenient.

Also, unlike HDF5, Zarr has better multithreading support.
