List of rebalance() Examples

Examples of rebalance()

com.linkedin.helix.manager.zk.ZKHelixAdmin.rebalance()
org.apache.helix.HelixAdmin.rebalance()
Rebalance a resource in cluster @param clusterName @param resourceName @param replica @param keyPrefix
org.apache.helix.manager.zk.ZKHelixAdmin.rebalance()
org.infinispan.distribution.ch.ConsistentHashFactory.rebalance()
Create a new consistent hash instance, based on an existing instance, but "balanced" according to the implementation's rules.
It must be possible to switch from the "intermediary" consistent hash that includes the old owners to the new consistent hash without any state transfer.
{@code rebalance(rebalance(ch))} must be equivalent to {@code rebalance(ch)}. @param baseCH An existing consistent hash instance, should not be {@code null} @return A new {@link ConsistentHash} instance, or {@code baseCH} if the existing instancedoes not need any changes.
org.infinispan.distribution.ch.DefaultConsistentHashFactory.rebalance()
org.infinispan.distribution.ch.impl.DefaultConsistentHashFactory.rebalance()
voldemort.client.rebalance.RebalanceController.rebalance()
Validate the plan, validate the cluster, and then kick off rebalance. @param rebalancePlan
