{"library":"fastparquet","type":"library","category":null,"description":"fastparquet is a Python library providing performant read/write support for the Parquet file format, without needing a Python-Java bridge. It integrates well with Python-based big data workflows, particularly Dask and Pandas (versions < 3.0). As of March 2026, with Pandas 3.0 explicitly depending on PyArrow, `fastparquet` is being retired, and no further development is anticipated, though it remains usable for Pandas 2.x users.","language":"python","status":"deprecated","version":"2026.3.0","tags":["parquet","data processing","dataframe","io","dask","pandas"],"install":[{"cmd":"pip install fastparquet","imports":["from fastparquet import ParquetFile","from fastparquet import write"]},{"cmd":"conda install -c conda-forge fastparquet","imports":[]}],"homepage":null,"github":"https://github.com/dask/fastparquet","docs":null,"changelog":null,"pypi":"https://pypi.org/project/fastparquet/","npm":null,"openapi_spec":null,"status_page":null,"smithery":null,"compatibility":{"summary":{"python_range":"3.10–3.9","success_rate":100,"avg_install_s":8.3,"avg_import_s":1.18,"wheel_type":"wheel"},"url":"https://checklist.day/v1/registry/fastparquet/compatibility"},"provenance":{"verified_status":"passing","verified_at":"Sun Jun 28","last_verified":"Sun Jun 28","next_check":"Tue Jul 28","install_tag":"verified"}}
