Hi Domenico, Thanks for the reply, I was not aware of those default options being passed into ArkMQ.org in a Kubernete3s cluster. We are using Ceph for S3-compatable storage in out Kubernetes cluster. We are also using the broker-init container to set other broker parameters that were not exposed through the CRD. Paul

This is why you don't see the journal-buffer-timeout in broker.xml. You could change the default options by using the environment variables: AMQ_JOURNAL_TYPE and AMQ_EXTRA_ARGS but it is not recommended because the storage type used in a Kubernetes cluster is usually a network storage with low performance. The domain ArtemisCloud.io was replaced by ArkMQ.org[2]. Starting from ArkMQ Operator[1] 1.0.17 you can use the broker properties to customize the settings in the broker.xml file[3].
