All Implemented Interfaces:

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

public class DenseVectorCountAggregatorFunction
extends CountAggregatorFunction

Specialized CountAggregatorFunction 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 values
