Features
Feature | Description | References |
Cross-zone high availability | The cross-zone high availability feature is supported to implement zone-disaster recovery. You can add the cross-zone compute unit (CU) type for a workspace to schedule and switch over deployments of the workspace across zones in the same city. If a zone to which the workspace belongs fails, the deployments can run as expected in the other zone. This effectively prevents service interruptions caused by faults in a single zone and ensures the continuity and high availability of deployments. | |
Operator profiling (public preview) | The operator profiling feature is supported to allow you to query the intermediate results of SQL deployments that are running. This feature simplifies the check of data correctness. | |
CloudMonitor | CloudMonitor can be selected when you purchase a Realtime Compute for Apache Flink workspace. CloudMonitor is free of charge and provides basic monitoring and alerting capabilities. Monitoring and alert management are free of charge. You are charged only for the text messages and voice notifications that are sent. | |
Search of deployments based on IP addresses | Search of deployments based on IP addresses is supported. If the connection between a TaskManager node and a third-party component such as MySQL is abnormal, you can enter the IP address of the TaskManager node in the search box on the Deployments page in the Realtime Compute for Apache Flink console to search for and locate the related deployment. This way, you can perform O&M operations to avoid risks. Note If you have upgraded the network architecture, the search of deployments based on IP addresses is not supported due to the change of the overall network environment. For more information, see Network architecture upgrade. | N/A |
Optimization of the Workflows feature (public preview) | Alerts can be sent if a task in a workflow fails. You can rerun a task, set the state of a failed task to successful, or terminate a task. | |
Startup or cancellation of multiple deployments at a time | Multiple deployments can be started or canceled at a time on the Deployments page in the Realtime Compute for Apache Flink console. | N/A |
