-----------------------------------
Summary: Aggregate.groupOnly support foldable expressions
Key: SPARK-38489
URL: https://issues.apache.org/jira/browse/SPARK-38489
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.3.0
Reporter: Yuming Wang
Assignee: Yuming Wang
Fix For: 3.3.0
{code:scala}
spark.range(200L).selectExpr("id AS a").createTempView("t1")
spark.range(300L).selectExpr("id AS b").createTempView("t2")
spark.sql("SELECT DISTINCT a AS newAlias FROM t1 LEFT JOIN t2 ON a =
b").explain(true)
{code}
Expected optimized plan:
{noformat}
== Optimized Logical Plan ==
Aggregate [newAlias#8L], [newAlias#8L]
+- Project [id#0L AS newAlias#8L]
+- Range (0, 200, step=1, splits=Some(2))
{noformat}
