For example, liveness probes could catch a deadlock, where an application is running, but unable to make progress. The event is recorded and the labeled is updated only when the Cassandra container’s readiness probe passes. customisable Cassandra config (cassandra.yaml, jvm.options, extra libs) customisable liveness / readiness probes automated rolling update of Cassandra cluster definition changes A readiness probe indicates if the application running inside the container is “ready” to serve requests.
