Optimize group by with limit by Dandandan · Pull Request #22009 · apache/datafusion

Dandandan · 2026-05-04T10:57:46Z

Which issue does this PR close?

Closes #.

Rationale for this change

ClickBench q17 aggregates by UserID, SearchPhrase and applies a small LIMIT. Building the full aggregate state can use substantially more memory than needed for queries where any limited set of grouping keys is sufficient.

This PR preselects a limited set of grouping keys before running the original aggregate, allowing existing join dynamic filtering to push that key set into the second input scan.

What changes are included in this PR?

Extends PushDownLimit to rewrite limited grouped aggregates with aggregate expressions when enable_distinct_aggregation_soft_limit is enabled.
Builds LIMIT K (GROUP BY keys) as a key preselection plan, then right-semi joins the original input against those keys before the final aggregate.

Are these changes tested?

Yes, existing tests

Are there any user-facing changes?

No API changes.

Yeah this is a pretty nice find 😄

I vaguely remember there have been previous attempts to do this (optimize GROUP BY with a LIMIT without an ORDER BY) but I can't find it now

While I think these queries are of limited practical import (it basically returns some arbitrary subset of the groups) given it has come up a few times, I think we should pursue this (especially since the code is relatively simple)

alamb · 2026-05-06T13:44:47Z

            Limit: skip=0, fetch=2
              Aggregate: groupBy=[[test.a]], aggr=[[sum(test.b)]]
-                TableScan: test
+                RightSemi Join: test.a = test.a


Did you consider adding a LIMIT directly to the GroupByHash operator? I am not sure how much extra complexity that is, but you could probably model similarly to a SUM(a FILTER key IN <hash table>)

Though it might add a lot more complexity 🤔

Or we could implement a special GroupBy operator, similar to what @avantgardnerio implemented for GROUPBY with a limit https://github.com/apache/datafusion/tree/main/datafusion/physical-plan/src/aggregates/topk)

alamb · 2026-05-06T13:45:35Z

    Ok(Transformed::yes(make_limit(skip, fetch, Arc::new(input))))
 }

+/// Rewrite `LIMIT K (GROUP BY keys, aggs)` into a key preselection followed


I would probably describe this more like:

SELECT aggs(...) GROUP BY keys LIMIT k
