--------------------------------
Summary: [C++] Consolidate utf8 benchmark
Key: ARROW-14269
URL: https://issues.apache.org/jira/browse/ARROW-14269
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Yibo Cai
Assignee: Yibo Cai
I find some trivial (and obviously irrelevant) changes to UTF8 validation code
may cause big variances to benchmark result.
UTF8 validation functions are inlined and called directly in benchmark. The
compiler may try to optimize them together with the benchmark loop.
Un-inline the benchmark-ed functions makes the result predictable and
explainable.
