------------------------------------
Assignee: Apache Spark
> Optimize SerializeFromObject for primitive array
> ------------------------------------------------
>
> Key: SPARK-17490
> URL: https://issues.apache.org/jira/browse/SPARK-17490
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: Kazuaki Ishizaki
> Assignee: Apache Spark
>
> In logical plan, {{SerializeFromObject}} for an array always use
> {{GenericArrayData}} as a destination. {{UnsafeArrayData}} could be used for
> an primitive array. This is a simple approach to solve issues that are
> addressed by SPARK-16043.
> Here is a motivating example.
> {code}
> sparkContext.parallelize(Seq(Array(1)), 1).toDS.map(e => e).show
> {code}
