============================= Announcing python-blosc 1.0.4 ============================= What is it? =========== A Python wrapper for the Blosc compression library. Blosc (http://blosc.pytables.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-blosc is a Python package that wraps it. What is new? ============ Optimized the amount of data copied during compression (using _PyBytes_Resize() now instead of previous PyBytes_FromStringAndSize()). This leads to improvements in compression speed ranging from 1.2x for highly compressible chunks up to 7x for mostly uncompressible data. Thanks to Valentin Haenel for this nice contribution.
