Quota serves as a computing resource pool of MaxCompute. It provides the CPU and memory resources that are required for computing jobs, such as MaxCompute SQL jobs, MapReduce jobs, Spark jobs, Mars jobs, and Machine Learning Platform for AI (PAI) jobs.
The unit of MaxCompute computing resources is compute unit (CU). One CU equals 1 CPU core and 4 GB of memory. Quotas are classified into subscription resource quotas and pay-as-you-go resource quotas based on the billing methods of resources. For more information about the billing methods, see Subscription.
- Configure quota groups
You can add, change, or remove quota groups. You can also configure resource scheduling periods for quota groups. This ensures that different projects can schedule computing resources in different periods of time.
- Change the quota group of a project
You can change the quota groups that are associated with a MaxCompute project.
- When you create a MaxCompute project, you can configure the quota group parameter to specify the quota group that you want to associate with the project.
- To change the quota group that is associated with an existing MaxCompute project, you can go to the MaxCompute console, find the project, and then click Switch quota group in the Actions column. You can also change the quota group that is associated with the project on the Projects tab of MaxCompute Management. For more information, see Change the quota group of a project.
