brooklyn.policy.loadbalancing
[Java] Class BalanceableWorkerPool

java.lang.Object
  groovy.lang.GroovyObjectSupport
      brooklyn.entity.basic.AbstractEntity
          brooklyn.policy.loadbalancing.BalanceableWorkerPool
All Implemented Interfaces:
Resizable
public class BalanceableWorkerPool
extends AbstractEntity

Represents an elastic group of "container" entities, each of which is capable of hosting "item" entities that perform work and consume the container's available resources (e.g. CPU or bandwidth). Auto-scaling and load-balancing policies can be attached to this pool to provide dynamic elasticity based on workrates reported by the individual item entities.

Nested Class Summary
static class BalanceableWorkerPool.ContainerItemPair

Encapsulates an item and a container; emitted for ITEM_ADDED, ITEM_REMOVED and ITEM_MOVED sensors.
