Hi, I’m trying to read a parquet file with a projection from Scala and I can’t find docs or examples for the correct way to do this.
I have the file schema and have filtered for the list of columns I need, so I have a List of ColumnDescriptors. It looks like I should call ParquetFileReader.setRequestedSchema() but I can’t find an example of constructing the required MessageType parameter. I’d appreciate any pointers on what to do next. Thanks, Andy.
