------------------------------------
Summary: Converting Table to pandas raises NotImplementedError
(when table previously saved as partitioned parquet dataset)
Key: ARROW-17636
URL: https://issues.apache.org/jira/browse/ARROW-17636
Project: Apache Arrow
Issue Type: Bug
Components: Python
Affects Versions: 9.0.0
Environment: Docker container, based on continuumio/anaconda3
Python 3.9.12
PyArrow 9.0.0
Reporter: Roberto Lobo
When converting a table in which one of the column's type is of DictionaryType
(values=int32, indices=int32, ordered=0) the conversion to pandas DataFrame
fails with:
NotImplementedError: dictionary<values=int32, indices=int32, ordered=0>
The dictionary has this conversion not implmented yet.
This DictionaryType is used as type when using one of the columns (Int64) as
one of the parquet's dataset partition columns.
