%description
Blosc (https://blosc.org) is a high performance compressor optimized
for binary data. It has been designed to transmit data to the processor
cache faster than the traditional, non-compressed, direct memory fetch
approach via a memcpy() OS call.

Blosc works well for compressing numerical arrays that contains data
with relatively low entropy, like sparse data, time series, grids with
regular-spaced values, etc.

python-blosc2 is a Python package that wraps C-Blosc2, the newest version
of the Blosc compressor. Currently python-blosc2 already reproduces the
API of python-blosc, so the former can be used as a drop-in replacement
for the later.
