📄️ Backup and Recovery
StarRocks supports backing up the current data as a file to a remote storage system via the broker (the broker is an optional process in the StarRocks cluster, mainly used to support StarRocks to read and write files and directories on the remote storage, please refer to the Broker Load documentation. The backup data can be restored from the remote storage system to any StarRocks cluster with the restore command. This feature supports periodic snapshot backup of data. It also allows migrating data between clusters.
📄️ Parameter Configuration
After the service is started, you may adjust the configuration parameters to meet the business requirements. You need to reboot the BE and Fe to apply the changes.
📄️ Monitor and Alerting
You can build your own monitoring services, or use the Prometheus + Grafana solution. StarRocks provides a Prometheus-compatible interface that directly links to the HTTP port of the BE and FE to obtain monitoring information from the cluster.

Administrators can recover the mistakenly deleted data with the RECOVER command.
