case class JoinProgram(left: SingleTableGeneratorProgram, right: SingleTableGeneratorProgram, groupSize: Int, joinType: JoinType, filter: Option[Program] = None, selector: Vector[Int], result: TabularData) extends SingleTableGeneratorProgram with Product with Serializable
A Program performing joins Note: the join operation is usually splitted into this operation and two selects which prepares the groups. See the Compiler.
- left
source for the left side, usually a select which also creates grouping
- right
source for the right side, usually a select which also creates grouping
- groupSize
prefix size of the groups, if 0 no grouping is performed.
- joinType
the join type. Encoding "inner", "left", "right", "outer"
- filter
the filter applied to each possible left/right possible row.
- selector
selected columns to return (from concatenated left and right side, including groups)
- result
result tabular type
