Compact more aggressively in TopK based upon memory usage by cetra3 · Pull Request #20381 · apache/datafusion

cetra3 · 2026-02-16T11:48:58Z

Which issue does this PR close?

Sort of addresses #19386

Rationale for this change

Compaction in TopK values currently uses some hard set heuristics to decide when to compact. Instead we can use the memory size of the batches as a bound.

What changes are included in this PR?

Adjusts TopK compaction to compact more aggressively, based upon memory size.

Are these changes tested?

Yes and a test has been added.

Are there any user-facing changes?

No

Benchmarks

I'm struggling (in this PR and other PRs...) to get some good reliable benchmarks through.

However with this one it seems like it's mostly the same speed as main or a little faster in some cases:

Hi @cetra3 ,
Can you address the remaining comments and take the PR forward ? This fix is quite useful for TopK queries

@bharath-techie I had replied to a comment about simplifying this further:

Actually simplifying this down, we get:
batches_size <= (batches_size / total_rows) * inner_len * 2

// Multiply both sides by total_rows:

batches_size * total_rows <= batches_size * inner_len * 2

// Divide both sides by batches_size:

total_rows <= inner_len * 2
So the batches size actually just cancels out. In light of this let me know if it's still something we want to pursue. I still see some perf gains with this strategy.

If you're OK with this I will do the change

@adriangb @Dandandan @alamb @kosiew sorry for the spam, this PR helps a lot in group by + top k kind of queries - can somebody please review and push the PR forward ?

TPC-DS:     10729.08ms → 10701.14ms  ~0.26% faster

I don't see a broad runtime win in these benchmark suites; the aggregate timings are essentially neutral/mixed.
