case class GroupArgs(dedupAttrs: Seq[Attribute], argOffsets: Array[Int], groupingOffsets: Seq[Int]) extends Product with Serializable
A helper class to pack the group related items for the Python input.
- dedupAttrs
the deduplicated attributes for the output of a Spark plan.
- argOffsets
the argument offsets which will be used to distinguish grouping columns and data columns by the Python workers.
- groupingOffsets
the grouping offsets(aka column indices) in the deduplicated attributes.
