Package org.elasticsearch.search.aggregations

Class MultiBucketConsumerService

java.lang.Object

org.elasticsearch.search.aggregations.MultiBucketConsumerService

public class MultiBucketConsumerService
extends Object

An aggregation service that creates instances of MultiBucketConsumerService.MultiBucketConsumer. The consumer is used by BucketsAggregator and InternalMultiBucketAggregation to limit the number of buckets created in Aggregator.buildAggregations(long[]) and InternalAggregation.reduce(java.util.List<org.elasticsearch.search.aggregations.InternalAggregation>, org.elasticsearch.search.aggregations.InternalAggregation.ReduceContext). The limit can be set by changing the `search.max_buckets` cluster setting and defaults to 65536.
