IntraBrokerDiskCapacityGoal()
Constructor for Capacity Goal.
|
Modifier and Type | Method and Description |
---|---|
protected SortedSet<Broker> |
brokersToBalance(ClusterModel clusterModel)
Get brokers in the cluster so that the rebalance process will go over to apply balancing actions to replicas
they contain.
|
ModelCompletenessRequirements |
clusterModelCompletenessRequirements()
Specify the load requirements for this goal.
|
void |
finish()
Signal for finishing the process for rebalance or self-healing for this goal.
|
protected void |
initGoalState(ClusterModel clusterModel,
OptimizationOptions optimizationOptions,
Optional<OptimizationMetrics> optimizationMetricsOpt)
Sanity checks: For each alive broker in the cluster, the load for
Resource.DISK less than the limiting capacity
determined by the total capacity of alive disks multiplied by the capacity threshold. |
boolean |
isHardGoal()
True if this is a hard goal, false otherwise.
|
String |
name()
Get the name of this goal.
|
ActionAcceptance |
partitionActionAcceptance(PartitionBalancingAction action,
ClusterModel clusterModel)
Checks if the action on the partition specified by the
PartitionBalancingAction
is acceptable. |
boolean |
partitionActionSelfSatisfied(ClusterModel clusterModel,
PartitionBalancingAction action)
Check if requirements of this goal are not violated if this partition action is applied
to the given cluster state, false otherwise.
|
protected void |
rebalanceForBroker(Broker broker,
ClusterModel clusterModel,
Set<Goal> optimizedGoals,
OptimizationOptions optimizationOptions)
Perform optimization via replica movement cross disks on broker to ensure balance: The load on each alive disk
is under the disk's the capacity limit.
|
ActionAcceptance |
replicaActionAcceptance(ReplicaBalancingAction action,
ClusterModel clusterModel)
Check whether the given action is acceptable by this goal.
|
boolean |
replicaActionSelfSatisfied(ClusterModel clusterModel,
ReplicaBalancingAction action)
Check if requirements of this goal are not violated if this action is applied to the given cluster state,
false otherwise.
|
protected void |
updateGoalState(ClusterModel clusterModel,
Set<String> excludedTopics)
Update goal state.

is acceptable.
For performance optimization purposes, it is recommended goals return the wider-level action acceptance first
(e.g ActionAcceptance.BROKER_REJECT
versus ActionAcceptance.REPLICA_REJECT
) as that helps
the proposal-generating logic short-circuit invalid proposal generations.action
