Class ResourceGroup

java.lang.Object

org.apache.pulsar.broker.resourcegroup.ResourceGroup

public class ResourceGroup
extends Object

The resource group (RG) data structure. One of these is created internally for every resource group configured. The RG name is considered a key, and must be unique. Being the key, the name can't be modified after the RG is created. Tenants and Namespaces directly reference RGs. The usage is "vertical": i.e., a tenant or namespace references the same RG across all of the monitoring classes it uses (Publish/Dispatch/...), instead of referencing one RG for publish, another one for dispatch, etc.

Nested Class Summary

Nested Classes

Modifier and Type	Class and Description
static class	ResourceGroup.BytesAndMessagesCount Convenience class for bytes and messages counts, which are used together in a lot of the following code.
protected static class	ResourceGroup.PerBrokerUsageStats
protected static class	ResourceGroup.PerMonitoringClassFields
static class	ResourceGroup.ResourceGroupMonitoringClass Usage "sense" for resource groups: publish and dispatch for now; may be more later (e.g., storage-monitoring) ToDo: "class" is vague; is there a better term to call this?
static class	ResourceGroup.ResourceGroupRefTypes The entities that might reference RGs are tenants, namespaces (and maybe topics, later).
