Multi-Tenancy Capability GBase 8a MPP Cluster provides multi-tenant capabilities through virtual cluster technology to achieve physical or logical isolation between tenants. The computing nodes are grouped into multiple virtual subsets within a virtual cluster, with each subset physically isolated on resources and logically separated in the namespace. The virtual cluster provides a unified access entry, metadata view, execution scheduling, authentication, and permission management for all subsets. On each computing node of a virtual subset, different application and user resource quotas and query priorities can be flexibly configured through resource management and resource groups. With a sound permission authorization and management mechanism, different applications can run in different virtual subsets, and different types of tasks of the same application can run in the same subset, but with different resource quotas and priorities, and necessary isolation is ensured. It's like running in a transparent "sandbox."
