        public static RowDataProjection create​(Schema schema,
                                               Schema projectedSchema)
        Creates a projecting wrapper for RowData rows.

        This projection will not project the nested children types of repeated types like lists and maps.

        Parameters:
        schema - schema of rows wrapped by this projection
        projectedSchema - result schema of the projected rows
        Returns:
        a wrapper to project rows
      • create

        public static RowDataProjection create​(org.apache.flink.table.types.logical.RowType rowType,

                                               Types.StructType projectedSchema)
        Creates a projecting wrapper for RowData rows.

        This projection will not project the nested children types of repeated types like lists and maps.

        Parameters:
        rowType - flink row type of rows wrapped by this projection
        schema - schema of rows wrapped by this projection
        projectedSchema - result schema of the projected rows
        Returns:
