> After SPARK-35378 was changed, I noticed that the execution of statements 
> such as ‘show parititions test' became slower.
> The change point is that the execution process changes from 
> ExecutedCommandEnec to CommandResultExec, but ExecutedCommandExec originally 
> implemented the following method
> override def executeToIterator(): Iterator[InternalRow] = 
> sideEffectResult.iterator
> CommandResultExec is not rewritten, so when the hasNext method is executed, a 
> job process is created, resulting in increased time-consuming
