perf: Merge Precision in-place by AdamGS · Pull Request #21219 · apache/datafusion

AdamGS · 2026-03-28T19:15:48Z

Which issue does this PR close?

Follow up of #20768.

Rationale for this change

Precision::min/max allocates a lot of new ScalarValues, and it can be done in place.
While running the sql_planner benchmark, it seems like for clickbench Statistics::try_merge_iter is a significant part of the runtime, and this PR improves that part by about 20-25% locally.

What changes are included in this PR?

Introduces a couple of of new internal functions to calculate the min/max of a Precision in-place.

Are these changes tested?

Existing general tests, and a few new unit tests.

Are there any user-facing changes?

None

File an issue against this benchmark runner

alamb · 2026-04-03T21:07:35Z

Benchmark results looks good to me -- thanks @AdamGS and @Dandandan

## Which issue does this PR close? Follow up of apache#20768. ## Rationale for this change `Precision::min/max` allocates a lot of new `ScalarValues`, and it can be done in place. While running the `sql_planner` benchmark, it seems like for clickbench `Statistics::try_merge_iter` is a significant part of the runtime, and this PR improves that part by about 20-25% locally. ## What changes are included in this PR? Introduces a couple of of new internal functions to calculate the min/max of a `Precision` in-place. ## Are these changes tested? Existing general tests, and a few new unit tests. ## Are there any user-facing changes? None --------- Signed-off-by: Adam Gutglick <adamgsal@gmail.com>
