=============================
Announcing python-blosc 1.2.7
=============================
What is new?
============
Updated to use c-blosc v1.6.1. Although that this supports AVX2, it is
not enabled in python-blosc because we still need a way to devise how to
detect AVX2 in the underlying platform.
At any rate, c-blosc 1.6.1 fixed an important bug in the blosclz codec that a release was deemed important.
For more info, you can have a look at the release notes in:
More docs and examples are available in the documentation site:
What is it?
===========
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 is the first compressor that is meant not only to reduce the size
of large datasets on-disk or in-memory, but also to accelerate object
manipulations that are memory-bound
how much speed it can achieve in some datasets.
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.
the Blosc compression library.
There is also a handy tool built on Blosc called Bloscpack
interface that allows you to compress large binary datafiles on-disk.
It also comes with a Python API that has built-in support for
serializing and deserializing Numpy arrays both on-disk and in-memory at
speeds that are competitive with regular Pickle/cPickle machinery.
Installing
==========
python-blosc is in PyPI repository, so installing it is easy:
$ pip install -U blosc # yes, you should omit the python- prefix
