Target customers: DataWorks users and big data developers and O&M personnel. Features released: Tasks may queue in shared resource groups of DataWorks, which causes the generation of task outputs to be delayed. Exclusive resource groups are used to fix this issue. Resource usage monitoring is now supported for exclusive resource groups. You can use the resource usage monitoring feature to view the following information: 1. The trend of the resource usage. 2. The status of task running and queuing, which helps you perform fine-grained scale-in or scale-out operations on resource groups. 3. The running tasks, which allows you to view resource consumption.
