AXFR with 25k records for each DHCP allocation is indeed "suboptimal" :-)
Have you considered using BIND's "new" DLZ dlopen()  for that? I'm
thinking dynamic update to BIND with your dlz driver updating PowerDNS'
backend record. Might be easier to implement than the two suggestions
above. Just a thought ...
