No plans to add Parquet support in the short term.
Shouldn't be too hard though. We just need to add a ParquetRecordParser that delegates to the official parquet-cpp implementation https://github.com/apache/parquet-cpp.
@jorgemarsal, thanks for clarification. At the moment I also don't have time for porting parquet-cpp, so will use SparkR in short term. Will try to return back and have a closer look on parquet-cpp integration.
