> Question: Can the `SinglePartitioned` mode handle multiple partitions in
parallel? This is the key goal we want to achieve. And you may want to change
the title to reflect this parallel need, too
Yes, from my understanding it can. It defines its required input
distribution as:
```rust
AggregateMode::FinalPartitioned | AggregateMode::SinglePartitioned => {
vec![Distribution::HashPartitioned(self.group_by.input_exprs())]
}
```
And then calls execute on each partition individually in its execute
function.
