Github user gatorsmile commented on the issue: https://github.com/apache/spark/pull/14452 For example, ```SQL WITH cte AS (SELECT * FROM testData a, testData b), cte2 AS (SELECT * FROM cte j1, cte) SELECT * FROM cte2 j3, cte j4 ``` Could you show the generated plan and explain how we can tell from the plan the subquery execution is reused? Thanks!
