Pipeline ParallelRunStep: Parquet Output

There seems to be a lack of documentation regarding possible output data of ParallelRunStep, as all the examples in documentation only mention writing the output as delimited file. Is there a possibility to use parquet as an alternative output format? I am currently facing the issue, that the output data contains several characters that kind of mess up AzureML's parsing ability for delimited files (newline characters within data, seperator characters within data, etc.).
