Subject [jira] [Created] (ARROW-6579) [Python] Parallel pyarrow.parquet.write_to_dataset
Date Tue, 17 Sep 2019 12:47:00 GMT
Adam Lippai created ARROW-6579:

             Summary: [Python] Parallel pyarrow.parquet.write_to_dataset
                 Key: ARROW-6579
             Project: Apache Arrow
          Issue Type: Improvement
    Affects Versions: 0.14.1
            Reporter: Adam Lippai

pyarrow.parquet.write_to_dataset() is single-threaded now and converts the table from/to Pandas.
We should lower the dataset writing to C++ (dropping Pandas usage) so it's easier to write
the partitioned dataset using multiple threads.
