org.elasticsearch.cluster.routing.allocation.allocator.BalancingRoundSummary.CombinedBalancingRoundSummary
- Record Components:
numberOfBalancingRounds- How many balancing round summaries are combined in this report.nodeNameToWeightChanges-numberOfShardMoves- The sum of shard moves for each balancing round being combined into a single summary.
- Enclosing class:
BalancingRoundSummary
public static record BalancingRoundSummary.CombinedBalancingRoundSummary(int numberOfBalancingRounds, Map<String,org.elasticsearch.cluster.routing.allocation.allocator.BalancingRoundSummary.NodesWeightsChanges> nodeNameToWeightChanges, long numberOfShardMoves)
extends Record
Holds combined
BalancingRoundSummary results. Essentially holds a list of the balancing events and the summed up changes
across all those events: what allocation work was done across some period of time.
TODO: WIP ES-10341
Note that each balancing round summary is the difference between, at the time, latest desired balance and the previous desired
balance. Each summary represents a step towards the next desired balance, which is based on presuming the previous desired balance is
reached. So combining them is roughly the difference between the first summary's previous desired balance and the last summary's
latest desired balance.-

combine
public static BalancingRoundSummary.CombinedBalancingRoundSummary combine(List<BalancingRoundSummary> summaries) Merges multipleBalancingRoundSummarysummaries into a singleBalancingRoundSummary.CombinedBalancingRoundSummary. -
toString
Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components. -
hashCode
public final int hashCode()Returns a hash code value for this object. The value is derived from the hash code of each of the record components. -
equals
Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared withObjects::equals(Object,Object); primitive components are compared with '=='. -
numberOfBalancingRounds
public int numberOfBalancingRounds()Returns the value of thenumberOfBalancingRoundsrecord component.- Returns:
- the value of the
numberOfBalancingRoundsrecord component
-
nodeNameToWeightChanges
public Map<String,org.elasticsearch.cluster.routing.allocation.allocator.BalancingRoundSummary.NodesWeightsChanges> nodeNameToWeightChanges()Returns the value of thenodeNameToWeightChangesrecord component.- Returns:
- the value of the
nodeNameToWeightChangesrecord component
-
numberOfShardMoves
public long numberOfShardMoves()Returns the value of thenumberOfShardMovesrecord component.- Returns:
- the value of the
numberOfShardMovesrecord component
