-----------------------------------
Labels: pull-request-available (was: )
> Improve a bit of performance for InsertAdaptiveSparkPlan
> --------------------------------------------------------
>
> Key: SPARK-54726
> URL: https://issues.apache.org/jira/browse/SPARK-54726
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 4.1.0
> Reporter: Jiaan Geng
> Assignee: Jiaan Geng
> Priority: Major
> Labels: pull-request-available
>
> The implementation of shouldApplyAQE show below.
> {code:java}
> private def shouldApplyAQE(plan: SparkPlan, isSubquery: Boolean): Boolean =
> {
> conf.getConf(SQLConf.ADAPTIVE_EXECUTION_FORCE_APPLY) || isSubquery || {
> plan.exists {
> case _: Exchange => true
> case p if !p.requiredChildDistribution.forall(_ ==
> UnspecifiedDistribution) => true
> // AQE framework has a different way to update the query plan in the
> UI: it updates the plan
> // at the end of execution, while non-AQE updates the plan before
> execution. If the cached
> // plan is already AQEed, the current plan must be AQEed as well so
> that the UI can get plan
> // update correctly.
> case i: InMemoryTableScanExec
> if i.relation.cachedPlan.isInstanceOf[AdaptiveSparkPlanExec] =>
> true
> case p => p.expressions.exists(_.exists {
> case _: SubqueryExpression => true
> case _ => false
> })
> }
> }
> }
> {code}
> We can improve the line.
