Function partitions_by_grouping_labels 

Source 
fn partitions_by_grouping_labels(aggregate: &AggregateExpr) -> bool
Expand description

Aggregations partitioning their input by the grouping labels, so that dropping input series by a grouping label drops exactly the matching output series and leaves the remaining aggregated values untouched.

Ranking aggregates instead retain input labels. count_values synthesizes a label.
