It excels at compressing binary data with low entropy\u2014sparse arrays, time series, regularly-spaced grids\u2014and supports multiple compression codecs (blosclz, lz4, lz4hc, zlib, zstd, and optionally snappy). The package provides straightforward Python functions for compression and decompression, with control over compression level, codec selection, and shuffle modes (shuffle and bitshuffle).\n\nThe package is production-stable and widely used in scientific and data-processing workflows. It has no runtime Python dependencies and ships with prebuilt wheels for most platforms, though it does require a C compiler if building from source. The maintainers note that Python-Blosc2 is a more modern alternative with additional features, but this package remains actively maintained and suitable for straightforward compression tasks.","worth_installing":"Yes, if you need fast compression of numerical or binary data. The package is stable, actively maintained, has no Python dependencies, and offers prebuilt wheels for common platforms. However, check whether Python-Blosc2 better suits your needs if you require more advanced features or plan a new project, as the maintainers recommend it as the more modern alternative."},"id":"blosc","links":{"html":"https://skillfed.io/packages/blosc","md":"https://skillfed.io/packages/blosc.md","pypi":"https://pypi.org/project/blosc/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-01-17","license_spdx":null,"license_treatment":"permissive","name":"blosc","python_support":"supports_current","summary":"Blosc data compressor"},"popularity":{"monthly_downloads":608604,"position":5779,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.11.4"}
