ENH: Disable sorting groups by default in `groupby`

[asemptote]

Feature Type

• Adding new functionality to pandas

• Changing existing functionality in pandas

• Removing existing functionality in pandas

Problem Description

The default sorting of groups is not relevant for most use cases and adds significant overhead for large dataframes. I find myself adding sort=False more often than not and am wondering if other users have a similar experience. As a rule of thumb, functions should reasonably do the minimum work needed by default and leave overhead functionality to non-default flags.

Feature Description

In pandas/core/frame.py#L9155:

def groupby(..., sort: bool = False, ...):
    ...

Alternative Solutions

from functools import partial

partial(df.groupby, sort=False)
