            Numbers in output of Flink WordCount in IntelliJ
            Asked 2021-Jan-21 at 21:32

            I am learning Apache Flink, and integrated it via Maven in IntelliJ. I tried this WordCount example from GitHub: WordCount example from GitHub

            where I simply adjusted the input text.

            The main part of the code producing the output is:

            ...

            WordCoiunt is the "hello world" in the streaming space.

            1. NUMBER shows the number of repetitions
            2. "florian" is twice in you input and shows up the first time with (florian,1) and the second occurs with (florian,2) if you add another "florian" to the input flink will count and show (florian,3)

            How does Flink countWindow work in detail
            Asked 2020-Sep-15 at 08:29

            I'm learning Flink with simple toy examples.

            I have adapted the WindowWordCount example from here and run it on this simple data file

            ...

            ANSWER

            Answered 2020-Sep-15 at 08:29

            The Trigger for CountWindow only triggers the window function for complete windows -- in other words, after processing windowSize events for a given key, then the window will fire.

            For example, with windowSize = 2, only for a and c are there enough events. Since there is only one b, the job ends with a partially filled window for b.

            You can use a custom trigger that also reacts to a timeout if you want to generate reports for partial count windows.

            QUESTION

            Computing variables before each iteration using the DataSet API in Apache Flink
            Asked 2020-Mar-03 at 08:50

            I am working with the clustering example provided with Flink (Kmeans) and trying to extend the functionality of it. The goal is to reduce the number of distance computations by computing a multidimensional-array consisting of the distances between each centroid, such that the distances can be found in a double[][] array. This array must be computed at the beginning of each iteration and broadcasted, when the points are assigned clusters.

            I have tried the following:

            ...

            ANSWER

            Answered 2020-Mar-03 at 08:50

            DataSets are inherently unordered and sharded, both which are not suited for your use case.

            What you want to do is to first collect all centroids in one method invocation.
