bind dns + mysql (sdb) = any good?

been tinkering with mysql, and i kinda like it... :lol:

anywho, i was looking at possibly moving bind dns into mysql... dlz looks confusing as hell, so i was wondering if anyone has tried sdb...

is there any performance gains from using bind with a mysql backend? does it handle zone updates well? (ie: do i have to update the zone serial by hand?)

thanks in advance

I've been thinking about using http://www.powerdns.com/ for a mysql powered DNS server

My understanding is that all db backed named servers are slower than local file name servers. That makes sense if you think about it. Bind will load the zone and cache it in memory whereas with a db involved it'll always need to query the db to make sure it has the latest data. There are ways Bind could cache the db records, but they would be complicated and require some sort of intermittent process to track db changes.

The only reason to move to db based zone files is for ease of management. At least that was the situation when I looked into it a few years ago. IIRC PowerDNS was even recommending ways to use Bind to front end it which involved some hackery with adding new domains.
