Behavior of Full/Delta polling for DNS Orchestrators

Default Full Snapshot Interval is 24 hours

Default Delta Snapshot Interval is 60 minutes

These are also the minimum allowed values for these timers.

DNS Records may rarely change. So, for optimal fetching behaviour, at every delta snapshot interval, Secure Workload will check if the serial numbers of any of the DNS zones has changed from the previous interval. If no zones have changed, no action is needed.

If any zones have changed, we will perform a zone transfer from all configured DNS zones (not just the single zone that has changed).

Every full snapshot interval, Secure Workload will perform zone transfer downloads from all zones and inject into the label database regardless of whether the zone serial numbers have changed.
