Description

Feature Type

• Adding new functionality to pandas
• Changing existing functionality in pandas
• Removing existing functionality in pandas

Problem Description

Currently df.convert_dtypes() will convert to nullable types (Int64, Boolean, etc), but it would be nice if there was an option to opt into the pyarrow-backed nullable types via pd.ArrowDtype

Feature Description

Maybe either

• New keyword argument nullable_type="pandas"|"pyarrow"
• Refactor io.nullable_backend global setting to mode.nullable_backend and allow that global config to apply to df.convert_dtypes

Alternative Solutions

For loop over the existing DataFrame object using astype and constructing pd.ArrowDtype?
