Class DenseVectorCountApproximateAggregatorFunction

java.lang.Object

org.elasticsearch.compute.aggregation.CountApproximateAggregatorFunction

org.elasticsearch.compute.aggregation.DenseVectorCountApproximateAggregatorFunction

All Implemented Interfaces:

Closeable, AutoCloseable, AggregatorFunction, org.elasticsearch.core.Releasable

public class DenseVectorCountApproximateAggregatorFunction
extends CountApproximateAggregatorFunction

Specialized CountApproximateAggregatorFunction for dense_vectors. Dense vectors are represented as multivalued fields, so we should only count 1 value for each dense_vector row instead of counting the number of dimensions.
