Expand description
A plan for generic TopKs that don’t fit any more specific category.
Fields
group_key: Vec<usize>
The columns that form the key for each group.
order_key: Vec<ColumnOrder>
Ordering that is used within each group.
limit: Option<usize>
Optionally, an upper bound on the per-group ordinal position of the records to produce from each group.
offset: usize
A lower bound on the per-group ordinal position of the records to produce from each group.
This can be set to zero to have no effect.
arity: usize
The number of columns in the input and output.
