Event-Driven Applications 1. ProcessFunctions ProcessFunction能够同时处理timers和state,这也是创建event-driven application的基础。 // compute the sum of the tips per hour for each driverDataStream<Tuple3<Long,Long,Float>>hourlyTips=fares.keyBy((TaxiFare fare)->fare.driverId).process(newPseudoWindow(...
简介 ProcessFunction将事件处理与定时器和状态结合起来,使其成为流处理应用的强大构件。这是用Flink创建事件驱动应用的基础。它与RichFlatMapFunction非常相似,但增加了定时器。 例子 如果你做过 "流分析 "培训中的实战练习,你会记得它使用TumblingEventTimeWindow来计算每个司机在每个小时内的小费总和,像这样。 1 2 ...
At this point, you have a complete application deployed on Azure. But there is much more that the Azure Developer CLI can do. These next steps will introduce you to additional commands that will make creating applications on Azure much easier. Using the Azure Developer CLI, ...
Event-driven ApplicationsSymbolic execution has proven itself a successful technique for automatically testing applications. However, it suffers from thestate explosionproblem, where execution of the program generates an exponential number of execution states that must be explored to fully cover the program...
The most common observation during IT modernization discovery is that there are many complex monolithic applications that are hard to modernize quickly. IT modernization is like moving into a new home. It would be the opportunity to clean up and to improve for business agility and strategic competi...
Services can be connected to create new applications without modifying producer or consumer, and with the ability to select a specific subset of events from a particular producer. The high level mission of Knative Eventing is:Enable asynchronous application development through event delivery from anywher...
The non-determism inherent in event-driven system encompassing both networked applications and interactive applications, makes these applications difficult to develop and maintain, despite the availability of powerful libraries. One reason for this is the so-called inversion of control needed to dispatch...
This architecture uses modern app development principles to create event-driven applications. Description of the illustration mad-event-driven-architecture.png I have reviewed and accept the Oracle Terms of Use. Example Use Case The Alarm on Log Data use case adopts the event-driven architecture to...

SEDA: An Architecture for Highly Concurrent Server ApplicationsSEDA 的概念最早是由 Matt Welsh 在其博士论文中提出的。若要进一步了解 SEDA,可以研究 Mule,它的架构就是基于 SEDA。 Event-Driven SOA: A Better Way to SOA:TIBCO 宣扬 Event-Driven SOA 的文章,可以学到一些概念。
