Add a project to the planner root so that rules know which output fields are used. One such rule is {{SemiJoinRule}}; it can only apply if it knows that no fields are used from the right-hand input, so it has to match a {{Project}} at the root of its pattern. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
