[I] Why uuid is only assigned for create_dataframe, not assigned for read_xxx [datafusion-python]
chenkovsky opened a new issue, #996:
URL: https://github.com/apache/datafusion-python/issues/996
I find that uuid is assigned for `create_dataframe`, but not for `read_csv`.
it's confusing, when I join two dataframe.
when I join dataframes created from `create_dataframe`, there's no column name conflict, because two dataframes have different qualifiers.
but it's not that case for read_csv.
maybe it's better to make these methods have similar behavior.
