**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** If an empty array is passed to `ArrowReader::get_record_reader_by_columns` it returns an error. **Describe the solution you'd like** It would be advantageous to support an empty projection within ParquetRecordBatchReader, and instead use file metadata to return the requisite number of rows. This will need the ability to create a RecordBatch with no columns and a non-zero row count #1536 **Describe alternatives you've considered** We could not add this functionality **Additional context** This would simplify the implementation of Hive based partitioning, amongst other things - https://github.com/apache/arrow-datafusion/pull/2000 -- This is an automated message from the Apache Git Service.
