…is reused ## What changes were proposed in this pull request? With this change, we can easily identify the plan difference when subquery is reused. When the reuse is enabled, the plan looks like ``` == Physical Plan == CollectLimit 1 +- *(1) Project [(Subquery subquery240 + ReusedSubquery Subquery subquery240) AS (scalarsubquery() + scalarsubquery())apache-spark-on-k8s#253] : :- Subquery subquery240 : : +- *(2) HashAggregate(keys=[], functions=[avg(cast(key#13 as bigint))], output=[avg(key)apache-spark-on-k8s#250]) : : +- Exchange SinglePartition : : +- *(1) HashAggregate(keys=[], functions=[partial_avg(cast(key#13 as bigint))], output=[sum#256, count#257L]) : : +- *(1) SerializeFromObject [knownnotnull(assertnotnull(input[0, org.apache.spark.sql.test.SQLTestData$TestData, true])).key AS key#13] : : +- Scan[obj#12] : +- ReusedSubquery Subquery subquery240 +- *(1) SerializeFromObject +- Scan[obj#12] ``` When the reuse is disabled, the plan looks like ``` == Physical Plan == CollectLimit 1 +- *(1) Project [(Subquery subquery286 + Subquery subquery287) AS (scalarsubquery() + scalarsubquery())apache-spark-on-k8s#299] : :- Subquery subquery286 : : +- *(2) HashAggregate(keys=[], functions=[avg(cast(key#13 as bigint))], output=[avg(key)apache-spark-on-k8s#296]) : : +- Exchange SinglePartition : : +- *(1) HashAggregate(keys=[], functions=[partial_avg(cast(key#13 as bigint))], output=[sum#302, count#303L]) : : +- *(1) SerializeFromObject [knownnotnull(assertnotnull(input[0, org.apache.spark.sql.test.SQLTestData$TestData, true])).key AS key#13] : : +- Scan[obj#12] : +- Subquery subquery287 : +- *(2) HashAggregate(keys=[], functions=[avg(cast(key#13 as bigint))], output=[avg(key)apache-spark-on-k8s#298]) : +- Exchange SinglePartition : +- *(1) HashAggregate(keys=[], functions=[partial_avg(cast(key#13 as bigint))], output=[sum#306, count#307L]) : +- *(1) SerializeFromObject [knownnotnull(assertnotnull(input[0, org.apache.spark.sql.test.SQLTestData$TestData, true])).key AS key#13] : +- Scan[obj#12] +- *(1) SerializeFromObject +- Scan[obj#12] ``` ## How was this patch tested?
