Lance Dacey created ARROW-9682:
----------------------------------
Summary: [Python] Unable to specify the partition style with
pq.write_to_dataset
Key: ARROW-9682
URL: https://issues.apache.org/jira/browse/ARROW-9682
Project: Apache Arrow
Issue Type: Improvement
Affects Versions: 1.0.0
Environment: Ubuntu 18.04
Python 3.7
Reporter: Lance Dacey
I am able to import and test DirectoryPartitioning but I am not able to figure
out a way to write a dataset using this feature. It seems like write_to_dataset
defaults to the "hive" style. Is there a way to test this?
{code:java}
from pyarrow.dataset import DirectoryPartitioning
partitioning = DirectoryPartitioning(pa.schema([("year", pa.int16()), ("month",
pa.int8()), ("day", pa.int8())]))
print(partitioning.parse("/2009/11/3"))
{code}
