Concrete methods
The underlying data expressions that supply input for the evaluation. These are used to fetch data from the data stores. There may be some expressions types that generate data and will have an empty set. Examples are constants, random, or time.

Attributes
Returns the final grouping for the expression. For non-grouped expressions this will be an empty list. If a multi-level group by is used, then this will return the grouping of the final result and ignore any intermediate groupings.

Attributes
Returns the grouping key generated for a given tag map. All keys for the group by must be present in the map.
