Limitations
Though it is standardized, full-zone transfer being described as one of the possible database replication mechanisms in RFC 1034 (incremental zone transfer described in RFC 1995), zone transfer is the most limited of those database replication mechanisms. Zone transfer operates in terms of "wire format" resource records, i.e. resource records as they are transferred using the DNS protocol. However, the schema of wire format resource records may not match the database schema used by the back ends of the DNS servers themselves.

Famous quotes containing the word limitations:
“Growing up means letting go of the dearest megalomaniacal dreams of our childhood. Growing up means knowing they can’t be fulfilled. Growing up means gaining the wisdom and skills to get what we want within the limitations imposed by reality—a reality which consists of diminished powers, restricted freedoms and, with the people we love, imperfect connections.”
—Judith Viorst (20th century)
“No man could bring himself to reveal his true character, and, above all, his true limitations as a citizen and a Christian, his true meannesses, his true imbecilities, to his friends, or even to his wife. Honest autobiography is therefore a contradiction in terms: the moment a man considers himself, even in petto, he tries to gild and fresco himself.”
—H.L. (Henry Lewis)
“Much of what contrives to create critical moments in parenting stems from a fundamental misunderstanding as to what the child is capable of at any given age. If a parent misjudges a child’s limitations as well as his own abilities, the potential exists for unreasonable expectations, frustration, disappointment and an unrealistic belief that what the child really needs is to be punished.”
—Lawrence Balter (20th century)
