I have added an article to my Wiki covering setup of PowerDNS with MySQL as well as enabling DNSSEC. I highly recommend using the MySQL database with replication (or even Percona XtraDB Cluster) as you will get a few nice advantages:
- Instant updates – no waiting for zone transfers
- Zone deletion works perfectly – you don’t get left with a bunch of zones you no longer host DNS for on the slaves
- Scales well – If you are hosting a very large number of zones that have frequent updates zone transfers do not seem to scale well
im interesting in read the wiki about this topic, this still exist some where?? the link to the wiki is broken.
