[GitHub] [arrow] rladeira commented on issue #1771: pyarrow-- reading selected columns from multiindex parquet file

   I found the same issue here, using pyarrow version '0.17.1'. I could not select columns from a multi index dataframe saved as a parquet file. Is there some way to accomplish this? Read just some columns from a multindex parquet file? Something like:
   
   `pd.read_parquet('file.parquet', engine='pyarrow', columns=[('a', 'b')])`
