Modern zone data replication using LMDB and Lightning Stream


As a follow up to my award-winning FOSDEM 2023 talk "Hosting your own DNS for 'fun' and zero profit", I'll provide an update covering my experiences using Lightning Stream for zone data replication between PowerDNS authoritative servers.

Lightning Stream offers significant advantages over traditional database-style replication (typically using relational databases like MariaDB and PostgreSQL), including simpler configuration, easier troubleshooting, and the ability add/remove cluster members without having to reconfigure existing cluster members (providing a very loosely coupled 'cluster').
