Hyper的Push模型是在2011年提出的,在这之前的SQL引擎,大都采用基于火山的Pull模型。已知基于Push构建的有Presto,Snowflake,Hyper,QuickStep,HANA,DuckDB(在2021年10月从Pull模型切换到了Push模型(详见参考文献[4]),Starrocks等。ClickHouse是个异类,在它自己的Meetup材料中,宣称自己是Pull和Push的组合,其中查询是采用...
因此,ClickHouse并不是传统的火山Pull模型实现,而是从查询计划树生成Pipeline执行计划。从火山Pull模型的Plan Tree生成Pipeline的方法是后序遍历,从没有Children 的Node开始构建第一个Pipeline,这是Push模型中生成Pipeline Operator的标准做法: QueryPipelinePtr QueryPlan::buildQueryPipeline(...) { struct Frame { Node ...

Low-speed signals in electronic components essentially use two types of circuit architectures to drive signals onto a bus. These are open-drain and push-pull protocols. Push-pull uses a CMOS buffer …
