Method Summary

Modifier and Type	Method	Description
BigArrays	bigArrays()
void	consumeBucketsAndMaybeBreak(int size)	Adds count buckets to the global count for the request and fails if this number is greater than the maximum number of buckets allowed in a response
static InternalAggregation.ReduceContext	forFinalReduction(BigArrays bigArrays, ScriptService scriptService, IntConsumer multiBucketConsumer, PipelineAggregator.PipelineTree pipelineTreeRoot)	Build a InternalAggregation.ReduceContext to perform the final reduction.
static InternalAggregation.ReduceContext	forPartialReduction(BigArrays bigArrays, ScriptService scriptService, Supplier<PipelineAggregator.PipelineTree> pipelineTreeForBwcSerialization)	Build a InternalAggregation.ReduceContext to perform a partial reduction.
boolean	isFinalReduce()	Returns true iff the current reduce phase is the final reduce phase.
Supplier<PipelineAggregator.PipelineTree>	pipelineTreeForBwcSerialization()	Supplies the pipelines when the result of the reduce is serialized to node versions that need pipeline aggregators to be serialized to them.
PipelineAggregator.PipelineTree	pipelineTreeRoot()	The root of the tree of pipeline aggregations for this request.

Method Details

forPartialReduction

public static InternalAggregation.ReduceContext forPartialReduction(BigArrays bigArrays,
 ScriptService scriptService,
 Supplier<PipelineAggregator.PipelineTree> pipelineTreeForBwcSerialization)

Build a InternalAggregation.ReduceContext to perform a partial reduction.

forFinalReduction

public static InternalAggregation.ReduceContext forFinalReduction(BigArrays bigArrays,
 ScriptService scriptService,
 IntConsumer multiBucketConsumer,
 PipelineAggregator.PipelineTree pipelineTreeRoot)

Build a InternalAggregation.ReduceContext to perform the final reduction.

Parameters:

pipelineTreeRoot - The root of tree of pipeline aggregations for this request

isFinalReduce

public boolean isFinalReduce()

Returns true iff the current reduce phase is the final reduce phase. This indicates if operations like pipeline aggregations should be applied or if specific features like minDocCount should be taken into account. Operations that are potentially losing information can only be applied during the final reduce phase.

bigArrays

public BigArrays bigArrays()

scriptService

public ScriptService scriptService()

pipelineTreeRoot

public PipelineAggregator.PipelineTree pipelineTreeRoot()

The root of the tree of pipeline aggregations for this request.

pipelineTreeForBwcSerialization

public Supplier<PipelineAggregator.PipelineTree> pipelineTreeForBwcSerialization()

Supplies the pipelines when the result of the reduce is serialized to node versions that need pipeline aggregators to be serialized to them.

consumeBucketsAndMaybeBreak

public void consumeBucketsAndMaybeBreak(int size)

Adds count buckets to the global count for the request and fails if this number is greater than the maximum number of buckets allowed in a response
