We want to forbid further operations to the DataFrame. But we don't have to forbid it, right? How about ``` class AlreadyOptimizedExecution(plan: LogicalPlan) { override lazy val analyzed: LogicalPlan = plan override lazy val optimizedPlan: LogicalPlan = plan } ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
