Python-Blosc2: Compress Better, Compute Bigger
Top-Notch Compression
Combine advanced codecs and filters for efficient lossless and lossy compression to reduce storage space while maintaining high performance.
Full-Fledged NDArrays
NDArray objects enable efficient storage and manipulation of arbitrarily large N-dimensional datasets, following the Array API standard, with an additional C API.
Compute Engine Inside
Combines compression with high-speed computation of complex mathematical expressions and reductions, while maintaining compatibility with NumPy.
Hierarchical Structures
Efficiently store data hierachically with the TreeStore class for convenience and optimized performance.
Flexible Storage
Access data from anywhere: read/write in memory or disk, stream from the network, or use memory-mapped files for high-performance I/O.
Uncomplicated Format
Blosc2’s format is simple and accessible, with specifications under 4000 words that make it easy to read and integrate.
