Keycloak on Distributed SQL (CockroachDB) - Part 2/2

In part one of this post, we configured a single Keycloak node to store it's data in a resilient and available CockroachDB. In this post we cover how to add more nodes to the cluster and ensure that the keycloak nodes are able to register themselves on CockroachDB which, then

Demo of CockroachDB surviving a regional outage

In this demo I'll show you one of the key characteristics of CockroachDB, its multi-regional survivability. CockroachDB clusters can easily spanning multiple geographic regions and replicate your data across those regions for maximum availability, in order to help you design systems with "always-on" requirements, which will help to drive negative
