fastparquet
JSON → 2026.3.0 verified Wed May 20 auth: no python install: verified deprecated
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.
