   @erenavsarogullari I manually tested the PR. Seems there is nothing in the 
nodes/edges
   ```
   spark.range(10000).toDF("value").write.parquet("/tmp/p1")
   
   spark.range(10000).toDF("value").write.parquet("/tmp/p2")
   
   spark.read.parquet("/tmp/p1").createOrReplaceTempView("t1")
   
   spark.read.parquet("/tmp/p2").createOrReplaceTempView("t2")
   
   
    spark.sql("select * from t1, t2 where t1.value=t2.value").show()
   ```
