Generate View Aggregation Data

Generate aggregation results for a view.

Executes each aggregation declared on the view against the transformations rows produced by the named functions inside the supplied timeWindow, applying the view's filters. Supported aggregation functions: count, count_distinct, sum, average, min, max. Grouped aggregations return up to 200 groups per aggregation; non-grouped aggregations return a single group with an empty groupName.

As with table-data, the functions field is required.
