TheNeuralBit opened a new issue, #24091: URL: https://github.com/apache/beam/issues/24091
### What happened? Pandas to_feather fails when used with a non-default index: ``` ValueError: feather does not support serializing a non-default index for the index; you can .reset_index() to make the index into column(s) ``` Unfortunately, our DataFrame partitions will only have a default index in rare cases. Typically each partition will have some hash-based index. So to_feather will usually fail with the above error at execution time. ### Issue Priority Priority: 2 ### Issue Component Component: dsl-dataframe -- This is an automated message from the Apache Git Service.
