Can dns clusters be improved?

Like real time syncing.

I notice when it syncs it deletes all DNS entries and add back in, how about checking if any changes have been made instead of deleting everything thus taking longer to sync ?

Another issue i found is that when deleting a domain and dns entry it does not allow me to add back the domain because another user “dns-cluster” still has that data.

I wonder it is faster as it sync up the full file in 1 go:

hestiacp/hestiacp/blob/44e3131312ed21f3e6a3132fb8e93f11ff07e0a1/bin/v-add-remote-dns-domain#L81-L83


      
          # Inserting synced records
          cluster_cmd v-insert-dns-records $DNS_USER $DOMAIN $tmp_file 'no'
          check_result $? "$HOST connection failed" "$E_CONNECT"

or

          # Syncing domain records
          tmp_file="/tmp/vst-sync.$DOMAIN"
          cluster_file "$USER_DATA/$user/dns/$DOMAIN.conf" "$tmp_file"
          check_result $? "$HOST connection failed" "$E_CONNECT"
          
          
cluster_cmd v-insert-dns-records "$DNS_USER" "$DOMAIN" "$tmp_file" 'no'
          check_result $? "$HOST connection failed" "$E_CONNECT"

Otherwise you need to check everything that takes every records seperately.

But currently working on some major rewrite to allow support for DNSSEC (DNSSEC – What Is It and Why Is It Important? - ICANN). How ever it is still in an early beta phase.
