Hopefully Bert can answer better than I can on this.
Have you read the documentation about writeing a backend?
http://doc.powerdns.com/master-backends.html
It says that the backend only needs to have these two function to functions as
a master backend and that what's I have done with the MongoDB backend.
Fredrik, you are right! The documentation states as you say:
"Periodically, PDNS queries backends for domains that may have changed,
and sends out notifications for slave nameservers."
It also says: "Some backends may be able to detect zone changes, others
may choose to let the operator indicate which zones have changed and
which haven't." (http://doc.powerdns.com/master.html)
So, please, be so kind as to answer one more question: When PDNS queries
backends for updated serials, does it provide them with a list of the
'notified_serial's (as per your explanation in a previous post of
yours), that is, a list of all serials which it has previously used in
notifications, or the backends have to maintain such a list (of
previously notified serials)?
Sorry, I may be becoming tiresome, but I have a hard time running
through the source code to find out this detail. I may have to find time
to read a bit about programming in C.
I have a hard role to play without a regular maintainer on the LDAP
backend.
Thank you VERY much for all the details you provide and your cooperation,
Nick
