Hi! I have PDNS 3.0 in a slave setup (not even answering queries, just fetching zones and writing them into a postgresql database).
Currently ~10 000 zones are configured. Every slave-cycle-interval=60 PDNS checks if the "refresh" is expired, thus causing 10 000 SOA queries, taking around 5 seconds. Currently this is not a problem, but when adding around 2 000 000 zones, that would take (if duration extends linear) around 1000 seconds, which would mean that I have to increase the slave-cycle-interval, causing much more delay in updating the zones. Is it just the way that PDNS queries all 2mio SOA records for refresh detection? This seems a bit inefficient. I currently use: distributor-threads=32 receiver-threads=8 Is there anything I can do to handle 2mio zones and still having a short slave-cycle-interval?
