Method Detail

updateConsistentHash

CompletionStage<Void> updateConsistentHash(CacheTopology cacheTopology)

Invoked when the CH has to be immediately updated because of a leave or when the state transfer has completed and we have to install a permanent CH (pendingCH == null). A state transfer is not always required.

rebalance

CompletionStage<Void> rebalance(CacheTopology cacheTopology)

Invoked when state transfer has to be started. The caller will not consider the local rebalance done when this method returns. Instead, the handler will have to call LocalTopologyManager.confirmRebalancePhase(String, int, int, Throwable)
