It wraps PyVista and zstandard to provide faster I/O with better compression ratios. The library automatically registers with PyVista's reader system, so once installed, pv.read() handles .pv files directly without additional imports.\n\nThe main advantage over VTK's XML format is speed and compression efficiency. According to the description, it achieves significantly higher write throughput (up to 1845 MB/s with threading) and better compression ratios (3.02 vs 2.52 for zlib) while using less disk space overall. It supports multi-threaded compression and decompression, and optimizes storage for fixed-width cell topologies by storing the cell width once instead of repeating it for every cell.","worth_installing":"Yes, if you work with VTK datasets in PyVista and care about I/O performance or file size. The package is actively maintained, has no known vulnerabilities, and integrates seamlessly with PyVista. Install friction is low. The MIT license poses no restrictions. Best suited for workflows where mesh file I/O is a performance concern; less critical for one-off analysis or small datasets."},"id":"pyvista-zstd","links":{"html":"https://skillfed.io/packages/pyvista-zstd","md":"https://skillfed.io/packages/pyvista-zstd.md","pypi":"https://pypi.org/project/pyvista-zstd/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-08-10","license_spdx":"MIT","license_treatment":"permissive","name":"pyvista-zstd","python_support":"supports_current","summary":"VTK zstandard compression library."},"popularity":{"monthly_downloads":88912,"position":13694,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.3.0"}
