Extended from the classic push and pull newsvendor models, this paper investigates the impact of firms' risk averse attitudes on supply chain performance. Based on firms' Conditional Value-at-Risk (CV aR), our
Simple diagram explaining some example differences between a push and pull promotional strategy The origin of these two terms refers to the supply chain and how the demand for the product is generated. Push strategy explained The term 'push strategy' describes the work a manufacturer of a product...
cacheMap是个Map结构,key为groupKey,是由dataId, group, tenant(租户)拼接的字符串;value为CacheData对象,每个dataId都会持有一个CacheData对象。 **获取配置** Nacos获取配置数据的逻辑比较简单,先取本地快照文件中的配置,如果本地文件不存在或者内容为空,则再通过HTTP请求从远端拉取对应dataId配置数据,并保存到...
Nacos 配置中心的几个核心概念: dataId 、 group 、 namespace ,它们的层级关系如下图: dataId :是配置中心里最基础的单元,它是一种 key-value 结构, key 通常是我们的配置文件名称,比如: application.yml 、 mybatis.xml ,而 value 是整个文件下的内容。 目前支持 JSON 、 XML 、 YAML 等多种配置格式。

There are few things that have to be considered when using a pull-up resistor with the open drain output configuration: Rising edge slope–The pull-up resistor in combination with the inherent capacitance of the line forms a low-pass filter. Depending on the value of the resistor and the ca...
推(push)、拉(pull)其实本质都是pull模式 在RocketMQ中,Consumer端的两种消费模式(Push/Pull)都是基于拉模式来获取消息的,而在Push模式只是对pull模式的一种封装,其本质实现为消息拉取线程在从服务器拉取到一批消息后,然后提交到消息消费线程池后,又“马不停蹄”的继续向服务器再次尝试拉取消息。如果未拉取到消...

ServerUrl. This value must point to the URL of the DSC pull service on the pull server machine. AllowUnsecureConnection. Note that we are using HTTP port 8080 to access the service, and in this simple example, we are using an unsecured connection, so we set the value to “True”. ...
