To the question of the data of only one facts collection place, horizontal scaling is clear. The more nodes you'll find, the larger the throughput amount. For aggregation queries, the question ask for will be sent for the corresponding vnodes initial, the vnodes will finish the aggregation operation, then the consumer will aggregate the question benefits from many vnodes for your next time. Since the quantity of vnodes is proscribed, aggregation queries have to have minor computation over the shopper side, Therefore the horizontal scalability functionality of aggregation queries is obtained.
Partitioning: In combination with sharding the info, TDengine also divides the time sequence data saved within a vnode In accordance with time intervals.
