AGGREGATE

For example, you can:

• Count the number of employees.
• Get the sum of a stream of prices.
• Pick the oldest person of a stream of persons.
• Extract the last percentile of a distribution.

You define aggregations with the AggregationFunction object.

For more information about Aggregation Functions, see their documentation.

You generally need only one aggregation and define it in the SingleAggregatorContainer.

If you want to process several aggregations at the same time, use the MultipleAggregatorContainer.
