Flink custom window assigner example

Flink에는 현재 이벤트 기준으로 몇분전/몇시간전/몇일전을 표현하는 window는 없다. Window API에서 event는 windows로 들어가지만 ( window assigner ), 각 이벤트에 대한 window evaulation이나 creation을 제어할 수 없다. fraud detection의 목표는 새 event가 들어왔을때 이전에 연관된 event와 함께 즉각적인 evaluation을 하는것이다. Window API는 custom trigger, evictor, window assigner를 정의할수 있게 제공하지만, 위의 요구사항을 만족시키긴 쉽지 않고, 깨지기 쉬운 로직이 된다.As I shared in the previous post, by default Flink starts window at clock boundary but using a second parameter to windowAll () we can customize the clock boundary.
