%description
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.
