See 4.5.0 release notes:

KCC improvements for sparse network replication

The Samba KCC will now be the default knowledge consistency checker in
Samba AD. Instead of using full mesh replication between every DC, the
KCC will set up connections to optimize replication latency and cost
(using site links to calculate the routes). This change should allow
larger domains to function significantly better in terms of replication
traffic and the time spent performing DRS replication.
