WebJul 30, 2024 · As you might know, Flink provides a powerful Window API that is applicable for a wide range of use cases. However, if you go over all of the available types of supported windows, you will realize that none of them exactly match our main requirement for this use case - the low-latency evaluation of each incoming transaction. WebFlink programs implement iterative algorithms by defining a step function and embedding it into a special iteration operator. There are two variants of this operator: Iterate and …
