giladkl opened a new pull request, #10728:
URL: https://github.com/apache/arrow-rs/pull/10728
# Which issue does this PR close?
- Closes #10727.
# Rationale for this change
The byte-view scalar comparison benchmarks in
arrow/benches/comparison_kernels.rs all run at one size: 1024 * 1024 * 8 =
8,388,608 rows, or 134 MB of views. That is far past cache, so they measure
memory bandwidth more than the per-row comparison, and only at a single point
on the size curve. Split out of #10689 at @alamb's request so it can go through
the automated benchmarking scripts first.
# What changes are included in this PR?
A new stringview_scalar_eq benchmark group running eq(StringViewArray,
StringViewArray::new_scalar("xxxx")) at 65,536 / 1,048,576 / 8,388,608 rows,
with Throughput::Elements so criterion reports elements/sec across the sizes.
Existing benchmarks are untouched.
# Are these changes tested?
yes
# Are there any user-facing changes?
no
