> Optimize VectorDotProduct for foldable inputs

> Key: SPARK-59532
> URL: https://issues.apache.org/jira/browse/SPARK-59532
> Project: Spark
> Issue Type: Improvement
> Components: ML, SQL
> Affects Versions: 5.0.0
> Reporter: Ruifeng Zheng
> Priority: Major
> Labels: pull-request-available
>
> VectorDotProduct decodes both vector structs and accesses both operands
> through ArrayData for every input row. When one operand is foldable, evaluate
> it once during code generation and cache its size, indices, and values using
> primitive data. Preserve the existing fallback for two dynamic operands and
> cover dense and sparse vectors in both operand positions.
