Supported Operations

The Grouping Engine has several built-in summaries such as:

*Int32Aggregate DoubleAggregate (Count, Min, Max, Sum) StringAggregate (MaxLength, Count) Count DistinctCount (Count, Values array) Vector (Values) DoubleVector (statistical methods: Median, Min, Max, 25% Quartile, 75% Quartile).

The engine supports summaries that operate on vectors such as Distinct Count, Median, 25% and 75% Quartile. Custom summaries may easily be added.
