TaQL node representing an array aggregate function.
Internal
This class is similar to TableExprAggrNode, but its result is an array instead of a scalar value. There are few aggregate functions resulting in an array. An example is gaggr
, which aggregates the non-empty arrays in a group into a single array. Other functions (like medians, runningmean, etc.) can be applied to its result making it quite versatile.
Most array aggregate functions are lazy to avoid using too much memory.
