Rather than converting dataframes to SQLite, running SQL, and converting back, QPD directly translates SQL into the native operations of each backend, which can be faster. It prioritizes correctness and consistency: for example, it follows SQL semantics for NULL handling in GROUP BY rather than the default pandas behavior of dropping null groups.\n\nThe package depends on pandas, triad, adagio, and antlr4-python3-runtime. It supports Python 3.7 through 3.10 and is classified as production-stable. However, it has been abandoned since 2023-07-12 with no updates since then, so it will not receive bug fixes or compatibility patches for newer versions of its dependencies or Python itself.","worth_installing":"Yes, if you need to run SQL on Pandas, Dask, or Ray and can tolerate an abandoned package. The low install friction and permissive license make it a low-risk experiment. However, do not rely on it for production workloads without testing thoroughly against your current dependency versions\u2014no updates have been released since 2023-07-12, so compatibility with newer pandas, Dask, Ray, or Python versions is not guaranteed."},"id":"qpd","links":{"html":"https://skillfed.io/packages/qpd","md":"https://skillfed.io/packages/qpd.md","pypi":"https://pypi.org/project/qpd/"},"maintenance":{"status":"abandoned"},"meta":{"latest_release":"2023-07-12","license_spdx":null,"license_treatment":"permissive","name":"qpd","python_support":"supports_current","summary":"Query Pandas Using SQL"},"popularity":{"monthly_downloads":350688,"position":7329,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.4.4"}
