Restart Doris Cluster

When using the Doris cluster, if you need to restart the cluster, you can modify the cluster configuration by using kubectl edit dc ${name} -n ${namespace}. To indicate the desired rolling restart for Doris cluster components, add the annotation al-assad.github.io/restartedAt to the Spec of the respective Doris cluster components, with the Value set to the current time. In the following example, annotations are set for the FE, BE, CN, and Broker components, indicating a rolling restart for all Pods of these three Doris cluster components. Depending on the actual situation, you can set annotations only for specific components.
