public class DenseVectorCountApproximateGroupingAggregatorFunction
extends CountApproximateGroupingAggregatorFunction

Specialized CountApproximateGroupingAggregatorFunction 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.
