                                         float threshold)

Creates a new RebalanceDecision, computing the explanation based on the decision parameters.

getCanRebalanceDecision

@Nullable
public Decision getCanRebalanceDecision()

Returns the decision for being allowed to rebalance the shard.

getNodeDecisions

@Nullable
public java.util.Map<java.lang.String,NodeRebalanceResult> getNodeDecisions()

Gets the individual node-level decisions that went into making the final decision as represented by RelocationDecision.getFinalDecisionType(). The map that is returned has the node id as the key and a NodeRebalanceResult.
