dongjoon-hyun opened a new pull request, #57014:
URL: https://github.com/apache/spark/pull/57014
### What changes were proposed in this pull request?
This PR adds wide-schema benchmark cases to `UnsafeProjectionBenchmark`: for
each of
`BooleanType`, `ByteType`, `ShortType`, `IntegerType`, and `FloatType`,
repeatedly
project a single row with 400 non-nullable fields of that type.
- One section per type, so a future improvement can be evaluated per type.
- A single row is projected repeatedly so the source stays in L1 cache and
the
field-write path is measured purely.
### Why are the changes needed?
The existing cases use at most 7 fields, so per-row fixed overhead dominates
and
improvements in the field-write path are not visible. With 400 fields, field
writing
dominates. A follow-up PR improving `UnsafeRowWriter`'s fixed-width field
writes will
use these cases to show before/after numbers.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Pass the CIs.
### Was this patch authored or co-authored using generative AI tooling?
