[SPARK-57036][SQL] Use intrinsic bulk-fill APIs for constant-value
WritableColumnVector methods
### What changes were proposed in this pull request?
Six bulk-fill methods on the column vectors implement constant-value
fills with degenerate per-element loops. This PR replaces them with
intrinsic substitutions:
| Method | Substitution |
| --- | --- |
| `OnHeapColumnVector.putBooleans(rowId, count, value)` |
`Arrays.fill(byte[], ..., (byte) v)` |
| `OnHeapColumnVector.putBytes(rowId, count, value)` | `Arrays.fill(byte[],
...)` |
| `OnHeapColumnVector.putShorts(rowId, count, value)` |
`Arrays.fill(short[], ...)` |
| `OnHeapColumnVector.putLongs(rowId, count, value)` | `Arrays.fill(long[],
...)` |
| `OffHeapColumnVector.putBooleans(rowId, count, value)` |
`Platform.setMemory` with small-count fallback |
| `OffHeapColumnVector.putBytes(rowId, count, value)` |
`Platform.setMemory` with small-count fallback |
The two OffHeap methods share a `SET_MEMORY_THRESHOLD = 128` constant.
Below the threshold, an inline byte loop avoids the JNI fixed cost of
`Unsafe.setMemory`; at or above, `setMemory` dominates and the gain
accelerates rapidly.
This PR also adds `WritableColumnVectorBulkFillBenchmark` to measure
these constant-value bulk-fill APIs across a count sweep covering both
the small-count (call-overhead dominated) and large-count (memory
bandwidth dominated) regimes.
### Why are the changes needed?
The bulk-fill APIs on `WritableColumnVector` are the natural call to
make from any column writer, but their implementations were per-element
loops. Switching to intrinsics:
- `Arrays.fill` is backed by HotSpot's `_jbyte_fill` / `_jshort_fill` /
`_jlong_fill` intrinsic stubs.
- `Unsafe.setMemory` lowers to a native `memset`. For OffHeap byte
fills the original per-byte `Platform.putByte` loop cannot be
vectorized through the JNI call, so the gain is dramatic at large
counts.
#### Benchmark numbers (GitHub Actions, JDK 17, Scala 2.13)
Measured by running `WritableColumnVectorBulkFillBenchmark` via the
`Run benchmarks` workflow on both the baseline (#56084) and this PR's
branch, so the two runs use identical hardware and JDK. Rate (M
elements/s):
**OffHeap byte fills (`putBytes` / `putBooleans`)** — the headline win:
| count | baseline | patched | delta |
| ------: | -------: | ------: | -----: |
| 1 | ~290 | ~240 | within run-to-run noise (~30%) |
| 8 | ~1,390 | ~1,280 | within run-to-run noise (~10%) |
| 64 | ~2,550 | ~2,450 | parity |
| 512 | ~2,700 | ~19,500 | **+7.2x** |
| 4,096 | ~2,770 | ~39,200 | **+14.1x** |
| 65,536 | ~2,780 | ~44,500 | **+16.0x** |
(Numbers averaged across `putBytes` and `putBooleans` since they share
the same code path.)
At and above the 128-element threshold, `setMemory` produces a 7-16x
improvement that grows with run length, consistent with `memset` being
amortized cleanly over long fills. Below the threshold, both runs use
the same inline byte loop, so the small differences at `count=1` and
`count=8` are GHA run-to-run variance rather than a structural change.
**OnHeap fills**: on the GHA runner (Linux + Zulu JDK 17) the C2
compiler already auto-vectorizes the original byte loop near the byte
memory-bandwidth ceiling, so `Arrays.fill` is at parity (~2,790 M/s,
unchanged across `putBooleans` / `putBytes` / `putShorts` / `putLongs`,
all counts, both baseline and patched). On Apple M4 Max + OpenJDK 21
the same change yields +5-33% in the small/medium count range. The
OnHeap changes are kept for consistency with the OffHeap fixes and to
avoid future divergence between platforms.
OffHeap multi-byte fills (`putShorts` / `putInts` / `putLongs` /
`putFloats` / `putDoubles`) are out of scope: `Platform.setMemory` is
byte-only and a value=0 short-circuit alternative was tried and showed
no measurable gain.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Existing tests; no behavior change. Ran locally:
- `VectorizedRleValuesReaderSuite`
- `ColumnVectorSuite`
- `ColumnarBatchSuite`
- `ParquetIOSuite`
237 tests, all pass.
### Was this patch authored or co-authored using generative AI tooling?
