CompositeAggregator

Executes a collection of aggregators against the same entry set and returns the list of results, one for each aggregator in the collection.

GroupAggregator

A wrapper aggregator that allows you to split entries in a set based on some criteria and to aggregate each subset separately and independently.

The important thing to note about the various average, max, min, and sum aggregators is that they differ from each other in how they treat the numeric values they are aggregating, as well as by the type of the return value.
