Parallel column is increasing the performance. I checked by creating multiple `ParquetRecordBatchStream<Reader>` for each column and all `ParquetRecordBatchStream<Reader>` reading parallely, performance increase from 60Mega Bytes / sec (when single `ParquetRecordBatchStream<Reader>` for a file) to 200 Mega Bytes / sec. Reading a Parquet files, all contains 8 columns and of size of approximately 250MB. -- This is an automated message from the Apache Git Service.
