Generate

case class Generate(generator: Generator, join: Boolean, outer: Boolean, output: Seq[Attribute], child: SparkPlan) extends SparkPlan with UnaryNode with Product with Serializable

:: DeveloperApi :: Applies a Generator to a stream of input rows, combining the output of each into a new stream of rows. This operation is similar to a flatMap in functional programming with one important additional feature, which allows the input rows to be joined with their output.

generator

the generator expression

join

when true, each output row is implicitly joined with the input tuple that produced it.

outer

when true, each input row will be output at least once, even if the output of the given generator is empty. outer has no effect when join is false.

output

the output attributes of this node, which constructed in analysis phase, and we can not change it, as the parent node bound with it already.
