final case class EquiJoin[T[_[_]], A](src: A, lBranch: FreeQS[T], rBranch: FreeQS[T], key: slamdata.Predef.List[(FreeMap[T], FreeMap[T])], f: JoinType, combine: JoinFunc[T]) extends Product with Serializable

This is an optional component of QScript that can be used instead of ThetaJoin. It’s easier to implement, but more restricted (where ThetaJoin has an arbitrary predicate to determine if a pair of records should be combined, EquiJoin has an expression on each side that is compared with simple equality).
