by Example

A supercluster is a set of clusters that have gateway connections established between them. A gateway connection bridges communication, specifically by propagating the subject-interest graph across clusters.

In practice, this means a client connecting to cluster A that is interested in using a service by a client connected to cluster B, messages will transparently flow across clusters without the client needing to have any knowledge of physical location.

This example shows how to setup a basic supercluster with two clusters. Note, if you are using JetStream, please refer to the dedicated Supercluster with JetStream example.
