For aggregation queries, the question ask for are going to be despatched on the corresponding vnodes 1st, the vnodes will finish the aggregation operation, then the client will combination the question effects from a number of vnodes for the 2nd time. Simply because the amount of vnodes is restricted, aggregation queries have to have little computation within the consumer side, And so the horizontal scalability capacity of aggregation queries is achieved.
