radmirnovii opened a new pull request, #24489:
URL: https://github.com/apache/datafusion/pull/24489
## Which issue does this PR close?
- Refs #24477.
## Rationale for this change
Spin-off of #24477: have a benchmark for `f(CASE-of-literals)` simplification
and evaluation available before the PR with the rule, to compare against
`main`.
## What changes are included in this PR?
A new `simplify_function_over_case` Criterion benchmark for
`datafusion-optimizer`: `simplify/{2,8,32}` (plan-time simplifier cost over N
literal branches) and `evaluate_8192_rows` (per-batch evaluation after the
standard simplification pipeline). Measurement coverage only; no behavior
change.
## Are these changes tested?
Yes: the benchmark compiles and runs on `main`
(`cargo bench -p datafusion-optimizer --bench simplify_function_over_case`);
fmt and clippy pass.
## Are there any user-facing changes?
No.
