I could not do this work yet.
I have a comment for the draft.
Section 3.2 mentions thousands of zones synchronization.
But there is a company which operates already over 50,000 zones in one
system.
The number of zones may be over 1 million on large scale DNS providers
or registrars.
Large number of zones case, DNS protocol may not work for
synchronization because there are many refresh check
queries/timers. If there are 1 million zones whose REFRESH is 3600, At
least 1000000/3600 = 277qps REFRESH queries are generated. It is not
realistic.
To resolve this problem, another zone synchronization mechanism is
required.
I'm sorry, but I do not understand....
in what context is 277 operations per second a large number?
AFAIK, a REFRESH operations (for no zone change) is a lightweight operation.
