CloudTable is a distributed and scalable key-value data storage service provided by HUAWEI CLOUD. CloudTable provides the following functions of the cluster mode on the web-based console.

• Cluster creation: You can create a cluster on the CloudTable Service console. It supports charging based on the number of computing units you selected when creating the cluster and the actual storage capacity. You can independently choose and install the advanced features, which are charged separately. You will be notified of renewal if your balance is insufficient for fee deduction. Cluster resources will be frozen during a retention period and unfrozen after your renewal. CloudTable helps you reduce costs as much as possible by adopting an architecture with computing isolated from storage and dynamically adjusting computing resources.
• Expanding the cluster capacity: Computing units of a cluster can be increased.
  • Increasing computing units: You can dynamically increase the number of computing units based on site requirements or service conditions to ensure read/write performance. Clusters can automatically implements load balancing to ensure service continuity and smooth capacity expansion. An extra fee will be generated when you increase computing units.
• Advanced feature: Currently, the CloudTable cluster mode supports the OpenTSDB and GeoMesa advanced features. You can choose to enable or disable advanced features. If the OpenTSDB advanced feature is enabled, it will be charged.
• Cluster management: You can manage clusters you create.
  • Monitoring metrics: CloudTable collects monitored metric data from a running cluster and reports it to Cloud Eye so that you can view cluster running status displayed in graphics. If there is an abnormal metric, CloudTable sends a message to notify you and administrators for immediate manual intervention.
  • Deleting a cluster: You can delete a cluster when you do not need it. Deleting a cluster is risky and may cause data loss. Before deleting a cluster, ensure that there is no running service and all data has been saved.
  • Restarting a cluster: After the HBase parameters of the cluster are modified or the system runs slowly due to running for a long time, you need to restart the cluster. Restart may cause data loss in running services. If you have to restart a cluster, ensure that there is no running service and all data has been saved.
  • Querying alarms: In case of a cluster operating exception or system failure, CloudTable will collect fault information and report it to the network management system for maintenance personnel to locate faults.
  • Querying logs: CloudTable records your operations on clusters to help you locate causes of a cluster running exception.
