It says: “TigerBeetle uses a single core by design and uses a single leader node to process events. Adding more nodes can therefore increase reliability, but not throughput.”
How does this work with multi-region? Does this mean that regardless of where in the world your users might live, they need to make a request to the leader node for a write to occur?
The way I understand it yes. Latency will be dictated by going to the leader node and replication to enough followers. The CAP theorem dictates that if you want strong consistency the way they offer you have to talk to a quorum of nodes IIRC N/2 + 1. Paxos and Raft also work that way.

Is distribution purely for redundancy?
