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,其中查询是采用了Pull模型。并且,在它的代码中,也一样是采用Pull字眼,作为查询调度核心驱动——PullingAsyncPipelineExecutor。在通过AST生成QueryPlan(逻辑计划)后,经过一些RBO优化,ClickHouse将QueryPlan按照后序遍历的方式将其转化为Pipeline,这种方...
The more linear slope on the output of the push-pull buffer may improve the linearity of a phase interpolator using the clock signals output from the push-pull buffers.Gregory A. King
A 24GHz CMOS LC-VCO with tuned push-pull buffer amplifier A low power, area-efficiency differential push-pull buffer amplifier with tuned output for mm-wave LC-VCO was presented in this paper. The push-pull techni... H Gao,G Su,J Su,... - Uk-europe-china Workshop on Millimeter ...
The present paper addresses an improved and compact low-power high-speed buffer amplifier topology for large-size liquid crystal display drivers. The propo... D Marano,G Palumbo,S Pennisi - International Symposium on Circuits & Systems 被引量: 1发表: 2011年 Push-pull amplifier circuit and oper...
另外,在这种情况下Broker和Consumer之间一直在进行请求和响应(long-polling变成了间隔为0的pull)。 考虑这样一种方式,它有long-polling的优势,同时能减少在有消息可读的情况下由Broker主动push消息给Consumer,减少不必要的请求。 消息中间件的Consumer实现 在消息中间件的Consumer中会有一个Buffer来缓存从Broker获取的消息...
In the complementary amplifier stage, in total there are three "pulling" elements - Q2 is a "pull-down" transistor when Vin is negative, Q1 is a "pull-up" transistor when Vin is positive, and the load RL is constantly a "pull-middle" resistor :-) simulate this circuit –Schematic crea...
Pull 模式 优点 缺点 实践操作 kafka的push、pull分别有什么优缺点 Kafka 是由 Apache 软件基金会开发的一个开源流处理平台,广泛应用于各大互联网公司的消息系统中。在 Kafka 中,生产者使用 push 模式将消息推送给 Kafka 集群,而消费者则使用 pull 模式从 Kafka 集群中拉取消息。本文对 Kafka 的 push 和 pull...
Push-pull approaches for peer-to-peer live streaming systems have gained tremendous popularity due to their high scalability and low latency. However, such approaches rely on buffer-map information of all neighbors to determine which piece to push and which peer to pull. Therefore, those approaches...

A delay locked loop that uses a differential push/pull buffer is provided. The differential push/pull buffer of the DLL is used to create a buffered output that closely follows the characteristics of the buffer's input over a range of temperature, power supply noise operating conditions, and ...
