@i7xh Two example: 1. Currently doris‘s concurrency control is based on tablet, one tablet ---> exec fragment， there is only one thread to deal with the data at query engine. If use pushed engine, could expand the computing thread num at run time. 2. In pull engine, if one fragment contains 3 or more node, like scan--> filter--> agg there is only one node is executing, but in push based engine, node executing could be async, for example scan and agg could execute at same time. -- This is an automated message from the Apache Git Service.
