According to KIP-968, this KIP introduces the public enum ResultOrder to determine whether keys are sorted in ascending or descending or unordered order. It Order is based on the serialized byte[] of the keys, not the 'logical' key order. employs the withDescendingKeys() and withAscendingKeys() methods to specify that the keys should be ordered in descending or ascending or unordered sequence, and the resultOrder() method to retrieve the value of enum value in ResultOrder. I've incorporated these variables and methods into the RangeQuery class and modified some method inputs. As a result, we can now use withDescendingKeys() to obtain results in reverse order and use withAscendingKeys to obtain the result in ascending order.
