NSD single record update without full reload

Question

I have a large zonefile (2 GB) that takes 15 minutes to load into nsd.

nsd-control reload zone

I would like to add a new record to the zonefile and avoid a full zone reload.

Is there a strategy to avoid the 15 minute reload when applying a single record update to the zonefile?

Use DNS dynamic updates instead? Also for NSD did you try the `zonec` command explicitely before reloading it? — Patrick Mevzek, Nov 21 '22 at 17:07

I hear NSD is best used as a secondary server, since it supports Zone Transfer and Incremental Zone Transfer, but not Dynamic DNS (DDNS).

One possible setup is to use a hidden DDNS-capable primary, with NSD public secondaries.
