❤Limitations of DStream API Batch Time Constraint application级别的设置. 不支持EventTime event time 比process time更重要 Weak support for Dataset/Dataframe No custom triggers 比如session的处理,当session跨越长时间,窗口处理也无法满足. NO Update sematic new event可能会update之前已经处理过的state…

part 4: topologically structured networks incorporating structure in networks of point neurons 如果我们使用神经元的生物学详细模型,那么很容易理解和实现拓扑的概念,因为我们已经有树突状乔木,轴突等,它们是神经系统内连接的物理先决条件. 但是,我们仍然可以通过使用点神经元网络来获得一定程度的特异性. 无论是在拓扑结构还是日常意义上,结构都可以被看作是一组规则,用于规定对象的位置以及它们之间的关系. 在点神…

1. Formula for Estimating the Average Number of Concurrent users We begin by defining what the number of concurrent users means. But before we do, the term login session has to be clarified first. A login session is a time interval defined by a start…
