blosc2

A fast, compressed, persistent binary data store library for C

Blosc is a high performance compressor optimized for binary data (i.e. floating point numbers, integers and booleans). 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 main goal is not just to reduce the size of large datasets on-disk or in-memory, but also to accelerate memory-bound computations. C-Blosc2 is the new major version of C-Blosc, and tries hard to be backward compatible with both the C-Blosc1 API and its in-memory format. However, the reverse thing is generally not true for the format; buffers generated with C-Blosc2 are not format-compatible with C-Blosc1 (i.e. forward compatibility is not supported). In case you want to ensure full API compatibility with C-Blosc1 API, define the BLOSC1_COMPAT symbol.
