All Implemented Interfaces:

Closeable, AutoCloseable, Releasable, SingleBucketAggregator

public class DiversifiedBytesHashSamplerAggregator
extends SamplerAggregator

Alternative, faster implementation for converting String keys to longs but with the potential for hash collisions.

buildDeferringCollector

public DeferringBucketCollector buildDeferringCollector()

Description copied from class: DeferableBucketAggregator

Build the DeferringBucketCollector. The default implementation replays all hits against the buckets selected by {#link DeferringBucketCollector.prepareSelectedBuckets(long...).

Overrides:
