    • Query Execution

      This work will involve:

      1. Adding a new QuerySolutionNode to represent a $group DocumentSource, called GroupNode
      2. Extending the SlotBasedStageBuilder to support translation of GroupNode to an sbe PlanStage. This would leverage the accumulator builders done in previous work.
      3. Using VirtualScanNode to unittest the translation of a simple QSN tree GroupNode --> VSN.
