> Struct type is not supported in MapWork with vectorization, it should be supported to
improve the performance.
> The following improvements will be implemented:
> * Add fields of struct type to VectorizedRowBatchCtx.
> * Improve the VectorizedParquetRecordReader to support the struct type for parquet file.
> Note:
> * Orc file won't be supported.
> * Filter operator won't be supported.
