java.lang.Object
- io.trino.execution.resourcegroups.InternalResourceGroup

All Implemented Interfaces:

ResourceGroup
```
@ThreadSafe
public class InternalResourceGroup
extends Object
implements ResourceGroup
```
Resource groups form a tree, and all access to a group is guarded by the root of the tree. Queries are submitted to leaf groups. Never to intermediate groups. Intermediate groups aggregate resource consumption from their children, and may have their own limitations that are enforced.
