      • constant

        public static java.lang.String constant​(int ttlInSeconds)
        TTL option for write with a constant TTL. When same values for TTL should be used for all rows in a bulk write call use this option.
        Parameters:
        ttlInSeconds - ttl value in seconds
        Returns:
        TTLOption

      • constant

        public static java.lang.String constant​(java.time.Duration duration)
        TTL option for write with a constant TTL. When same values for TTL should be used for all rows in a bulk write call use this option.
        Parameters:
        duration - ttl value in Duration
        Returns:
        TTLOption

      • perRow

        public static java.lang.String perRow​(java.lang.String ttlColumnName)
        TTL option for writes with TTL per Row. When different TTL has to be used for different rows in a bulk write call use this option. It expects the input RDD to supply the TTL values as an additional column at each row of the RDD. The TTL value provider column is selected by ttlColumnName
        Parameters:
        ttlColumnName - column name which has TTL values for each row
        Returns:
        TTLOption
