Labels: pull-request-available (was: )
> Add WritableColumnVectorBulkFillBenchmark
> -----------------------------------------
>
> Key: SPARK-57042
> URL: https://issues.apache.org/jira/browse/SPARK-57042
> Project: Spark
> Issue Type: Test
> Components: SQL
> Affects Versions: 4.3.0
> Reporter: L. C. Hsieh
> Assignee: L. C. Hsieh
> Priority: Minor
> Labels: pull-request-available
>
> Currently there is no benchmark covering the constant-value bulk-fill
> APIs on WritableColumnVector (putBooleans, putBytes, putShorts, putInts,
> putLongs, putNulls). SPARK-57024 and SPARK-57036 are optimizing several
> of these methods; this benchmark establishes a stable baseline so future
> optimizations can be tracked.
> The benchmark sweeps count = 1, 8, 64, 512, 4096, 65536 to cover both
> the call-overhead dominated regime (small count) and the memory
> bandwidth dominated regime (large count). Each case runs on both
> OnHeapColumnVector and OffHeapColumnVector.
