    Description

      The introduction of the same node communication over memory effectively disables FlowControl mechanism that prevents DEC receive queue from overloading in case of a slow consumer somewhere in query execution pipeline.
      This issue enables FlowControl for the same node communication processing path. See docs/Control flow.md in the engine repo for details on how ControlFlow works.
