public class DenseVectorCountGroupingAggregatorFunction
extends CountGroupingAggregatorFunction

Specialized CountGroupingAggregatorFunction 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
