是否有更优雅的过滤方式基于一组字符串中的值？

def myFilter(actions: Set[String], myDF: DataFrame): DataFrame = {
  val containsAction = udf((action: String) => {
    actions.contains(action)
  })

  myDF.filter(containsAction('action))
}

在SQL中你可以做到

select * from myTable where action in ('action1', 'action2', 'action3')
