[jira] [Created] (PARQUET-568) Read only specified top-level columns

Aliaksei Sandryhaila created PARQUET-568:
--------------------------------------------

             Summary: Read only specified top-level columns
                 Key: PARQUET-568
                 URL: https://issues.apache.org/jira/browse/PARQUET-568
             Project: Parquet
          Issue Type: Improvement
          Components: parquet-cpp
            Reporter: Aliaksei Sandryhaila
            Assignee: Aliaksei Sandryhaila


At the moment, `ParquetFileReader` instantiates Scanners for all columns and reads contents of all columns. We should be able to specify a subset of top-level columns to be read.
