上图表示,Process Time上,每两分钟各个窗口都输出一次数据。Spark streaming中micro-batch就是对齐延时的一种实现。好处是会定期输出结果。缺点是如果数据有负载高峰,在tps很高的时候,系统的负载也会很高。会导致延时。非对齐延时的代码实现如下: PCollection<KV<Team, Integer>> scores = input .apply(Window.into(F...

Event streaming revolves around the unbounded, sequential and real-time flow of data records, called "events,” foundational data structures that record any occurrence in the system or environment. It’s a term that essentially refers to every data point in the system. Therefore, a “stream” ...
Ability to process different EDI message types in a single mapping – allows users to define multiple EDI mappings in a single design so that MapForce can automatically determine a suitable mapping based on the incoming message that has been received. ...
Streaming detectionDetect anomalies in your streaming data by using previously seen data points to determine if your latest one is an anomaly. This operation generates a model using the data points you send, and determines if the target point is an anomaly. By calling the API with each new da...
When choosing the best live streaming software to use for your broadcasting needs, you need to consider the type of system you will be working with. You need to know what operating system your computer uses, and how much RAM and storage your computer has. ...
