   @tustvold maybe I get your idea wrong but I can't reproduce it in any ways
   
   ```
   message table {
               repeated group my_group_map {
                   REQUIRED BYTE_ARRAY kek;
                   optional group map (MAP) {
                       repeated group key_value {
                           REQUIRED BYTE_ARRAY key;
                           OPTIONAL group nested_map (MAP) {
                               repeated group key_value {
                                   REQUIRED BYTE_ARRAY key;
                                   REQUIRED BYTE_ARRAY value;
                               }
                           }
                       }
                   }
               }
               
           }
   
   ```
