[jira] [Created] (PARQUET-1393) [C++] Change parquet::arrow::FileReader::ReadRowGroups to read into continuous arrays

------------------------------------

             Summary: [C++] Change parquet::arrow::FileReader::ReadRowGroups to read into continuous arrays
                 Key: PARQUET-1393
                 URL: https://issues.apache.org/jira/browse/PARQUET-1393
             Project: Parquet
          Issue Type: New Feature
          Components: parquet-cpp
            Reporter: Uwe L. Korn
             Fix For: cpp-1.6.0


Instead of creating a chunk per RowGroup, we should read at least for primitive type into a single, pre-allocated Array. This needs some new functionality in the Record reader classes and thus should be done after https://github.com/apache/parquet-cpp/pull/462 is merged.
