Multi region with only 2 connections

Hi everyone,

I’m starting playing with cockroachDB and i would like to know if it’s possible to have multiple datacenter, but all DC will not be connected to every DC. It will be connected to at least 2 others DC.

Is it possible to have a setup like that and have the data everywhere ?


All nodes in a CockroachDB cluster must be able to talk to each other directly. CockroachDB clusters will not function properly without this.

Please see the production checklist for details on how nodes can be configured in various scenarios.


Thx :slight_smile:

Just to be sure i understand, so if we are using multiple region, each nodes inside the region should be able to communicate to all the nodes.


Hi @haplo37,

Yes, all nodes need to communicate with all nodes.
