   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   
   Currently the parquet -> arrow conversion supports the 3-level representation of lists, as described [here](https://github.com/apache/parquet-format/blob/master/LogicalTypes.md#lists).
   
   However, there is limited support for alternative representations as described [here](https://github.com/apache/parquet-format/blob/master/LogicalTypes.md#backward-compatibility-rules). In particular
   
   * No test coverage of fallback representations for List annotated types
   * No support for repeated fields outside of List annotated types
   
   **Describe the solution you'd like**
   
   We should support the parquet specification
