Modern zone replication using LMDB and Lightning Stream
Abstract
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 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 to add/remove cluster members without having to reconfigure existing cluster members (providing a very loosely coupled 'cluster').
