[Pdns-users] Immediate update visibility

[Daniel Miller]

I started to ask how to do something apparently non-standard - which 
probably means I'm doing it wrong.

I'm locally hosting my domain records using the authoritative server and 
also using a recursor. The recursor is configured with a list of 
forward-zones. My master server just has the auth & recursor running (on 
different internal IPs) - my slave server uses dnsdist in front of its 
own instances of auth & recursor (I'm still getting used to dnsdist).

I include all that just in case it's relevant - but I had this issue 
prior to dnsdist and prior to replication so I'm hoping not.

Anyway, after all that - when I make a change to a domain record using 
pdnsutil or an external tool using the API - the changes are immediately 
applied to the zone but are not immediately visible through the 
recursor. To make that happen I need to either flush the cache or just 
restart the recursor.

This is an issue when creating/updating ACME challenge records - I 
haven't been able to totally automate the process. I need to introduce 
lengthy delays, try manually applying the changes, restart the servers, 
whatever.

So - either I'm just doing this wrong (likely) or I need to ask: is 
there a way to make changes in the auth server immediately visible in 
the recursor? Possibly by explicitly disabling caching for the internal 
zones? Probably a bad idea but I can't think how else to accomplish 
this.
