Hi,

I'm not familiar with the particular algorithm, but you can most probably use one of the two iterate operators in Flink.

You can read a description and see some examples in the documentation: 

http://flink.apache.org/docs/0.8/programming_guide.html#iteration-operators

Let us know if you have any questions!

Cheers,

V.

Hi,

We are trying to develop the Apriori algorith with the Flink for our Data minning project.

In our understanding, Flink could handle loop within the workflow.

However, our knowledge is limited and we cannot find a nice way to do it.

Here is the flow of my algorithm :

GenerateCandidates ----> CalculateFrequentItemSet

mapper                      ----> reducer

We would like to use the reducer result as the mapper's entry for a predefined number of times (loop x times).

Is there any smart way to that with Flink. Or should we just copy paste the loop x times ?

Thank you,
