Uwe L. Korn created ARROW-3388:
----------------------------------

             Summary: [Python] boolean Partition keys in ParquetDataset are reconstructed as string
                 Key: ARROW-3388
                 URL: https://issues.apache.org/jira/browse/ARROW-3388
             Project: Apache Arrow
          Issue Type: Bug
          Components: Python
            Reporter: Uwe L. Korn
             Fix For: 0.12.0


Saving a {{ParquetDataset}} using a boolean column as a partitioning column will store {{True/False}} as the values in the path. On reload these columns will then be string columns with the values {{'True'}} and {{'False'}}.
