             Summary: Specialize ColumnReaders based on the column type
                 Key: PARQUET-433
                 URL: https://issues.apache.org/jira/browse/PARQUET-433

          Issue Type: Improvement
          Components: parquet-cpp

ColumnReader class is used to read columns of all types. This leads to a lot of type checking and 'switch' statements. ColumnReaders should be specialized to different types, while sharing the same interface.
