Varun Patil updated ARROW-8418:
-------------------------------
Priority: Trivial (was: Major)
> [Python] partition_filename_cb in write_to_dataset should be passed
> additional keyword arguments rather than just keys
> ----------------------------------------------------------------------------------------------------------------------
>
> Key: ARROW-8418
> URL: https://issues.apache.org/jira/browse/ARROW-8418
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python
> Reporter: Varun Patil
> Priority: Trivial
> Labels: easyfix, newbie
>
> I recently had a requirement where I would have liked to construct a filename
> based on additional context from Apache Airflow (specifically execution_date).
> It would be nice to pass the additional kwargs to *partition_filename_cb* so
> that the filename can be constructed using additional information rather than
> just the keys used for partitioning.
> I believe the fix should be as simple as passing kwargs to the
> *partition_filename_cb* inside *write_to_dataset.*
