      • compareValuesAndCheckForIncreasingTimestamp

        public static boolean compareValuesAndCheckForIncreasingTimestamp​(byte[] left,
                                                                  byte[] right)
        Parameters:
        left - the serialized byte array of the old record in state store
        right - the serialized byte array of the new record being processed
        Returns:
        true if the two serialized values are the same (excluding timestamp) or if the timestamp of right is less than left (indicating out of order record) false otherwise
