%description
Blosc is a high performance compressor optimized for binary data
(i.e. floating-point numbers, integers, and booleans, although it can handle
string data too). 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 is 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.
