case class ExprId(id: Long, jvmId: UUID) extends Product with Serializable

A globally unique id for a given named expression. Used to identify which attribute output by a relation is being referenced in a subsequent computation.

The id field is unique within a given JVM, while the uuid is used to uniquely identify JVMs.
