而持续时间校准是一个更为重要的功能,从根本上解决了1.0版本时间戳和系统时间偏离的问题。这样,tscns基本上可以代替标准系统时钟(clock_gettime/gettimeofday/std::chrono::XXX_clock)来使用。 这个功能需要用户周期性的在后台调用tscns.calibrate()函数,使tscns能够动态调整内部参数,与系统时间紧密同步。同时,tscns可...

上图列出了java.time包下的类,接下来我们详细看下其中每个类的用法。Clock:获取到当前时间点,包含时区信息,该类是抽象类,其实现类由其内部类实现,也可以自定义其实现类。Clock方法描述:getZone():获取创建日期时间的时区;withZone(ZoneId zone):返回 java window时钟 System java 抽象类 转载 fjfdh 2023-07...
Watermark是Apache Flink为了处理EventTime窗口计算提出的一种机制,本质上也是一种时间戳,由Apache Flink Source或者自定义的Watermark生成器按照需求Punctuated或者Periodic两种方式生成的一种系统Event,与普通数据流Event一样流转到对应的下游算子,接收到Watermark Event的算子以此不断调整自己管理的EventTime Clock。
