Blosc: A Technical Explanation of the C++ Data Compression Library Designed for Speed

1. Overview Blosc (pronounced /blɒsk/) is a high-performance C library focused on binary data compression, providing an extremely simple C++ interface. Its design philosophy is fundamentally different from traditional compression libraries (such as zlib or LZMA): its primary goal is not the ultimate compression ratio, but the ultimate compression/decompression speed, aiming to achieve “the speed … Read more
