fastparquet has not been actively maintained and lacks Python 3.14 support. PyArrow is now the standard for Parquet operations and is better maintained with broader community support. Changes: - Remove pyathena/fastparquet/ module - Remove tests/pyathena/fastparquet/ tests - Remove fastparquet from pyproject.toml dependencies - Update pyathena/pandas/result_set.py to use PyArrow only - Remove fastparquet test cases from pandas cursor tests - Remove fastparquet test table from create_table.sql.jinja2 - Update README.rst and docs/introduction.rst BREAKING CHANGE: Users explicitly using engine="fastparquet" must migrate to engine="pyarrow" (the default). The "auto" engine selection already preferred PyArrow, so most users are unaffected. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
