description = """
Blosc2 is a high-performance compressor and data format optimized for binary
data, including numerical arrays, tensors, and other structured formats. It
provides a flexible framework of codecs and filters, enabling developers to
balance compression speed and ratio for specific use cases, from high-throughput
data pipelines to persistent storage. As the successor to the original Blosc
library (released in 2010), Blosc2 is built on a mature foundation and is
integrated into many popular scientific computing libraries, such as PyTables,
h5py, and Zarr.

C-Blosc2 is the latest 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 (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.
