TDigestArrayAggregatorBase

abstract class TDigestArrayAggregatorBase[V] extends Aggregator[V, Array[TDigest], Array[TDigest]]

A base class for aggregating over array-like collections of values. Supplies all Aggregator methods except reduce, which is class specific. Maintains and returns an Array[TDigest], regardless of specific input type.

V

the specific array-like column type expected from input column
