Description

Feature Type

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

Problem Description

df.join() does not retain the attrs of the dataset. Given that the attrs manual states that "many operations that create new datasets will retain attrs", this seems like an omission.

Feature Description

Join is different from concat because there is a clear dataframe that the operation is on. Therefore, it would seem natural if df.join() would retain the attrs of the initial dataframe.

Alternative Solutions

It would also be possible to make the attrs dependent on "how" but this would only be natural for "left" and "right".
