TL;DR I want to apply scalar subquery to optimize `FPGrowthModel.transform`, there are two options: 1, create temp views and use `spark.sql`, see https://github.com/apache/spark/commit/63595ba03d9f18fe0b43bfb09f974ea50cb2c651; 2, add `private[spark] def withScalarSubquery(colName: String, subquery: Dataset[_]): DataFrame`, it seems much more convenient but not sure whether it is a proper way. cc @cloud-fan @HyukjinKwon -- This is an automated message from the Apache Git Service.
