Thanks, I didn't expect the topic to move so quickly

Out of curiosity, do you also intend not to require these dependencies in the pre-built wheel?
https://github.com/chdb-io/chdb/blob/main/setup.py#L177

        setup(
            packages=["chdb"],
            version=versionStr,
            package_data={"chdb": pkg_files},
            exclude_package_data={"": ["*.pyc", "src/**"]},
            ext_modules=ext_modules,
            python_requires=">=3.8",

@wudidapaopao I think it's reasonable to remove pyarrow and pandas as necessary deps. And we should run our unit tests in 2 groups w/ and w/o pyarrow and pandas.
