Hi Andre, I'm happy you were able to solve your problem :) Improvements to the documentation are always welcome! To me ST != WT is straight-forward from the javadocs, but I guess it wouldn't hurt to stress it in the docs. Do you think you could simplify your implementation a bit to make for a nic

Hi Vasia! Many thanks for your reply! Your hints finally enabled me implementing the problems first-choice solution using delta iteration: https://gist.github.com/p3et/12deb7d6321b48e9efab Do you think this could be worth to be contributed as an example within the Flink documentation? The exa

Hi Fabian, thanks for your fast reply! I created a gist to explain the while-not-empty loop in more detail: https://gist.github.com/p3et/9f6e56cf0b68213e3e2b It is an approach to create a minimal example of the kind of algorithm corresponding to page 1 of the PDF, in particular frequent substr

Hi Andre, Thanks for reaching out to the Flink community! I am not sure your analysis is based on correct assumptions about Flink's delta iterations. Flink's delta iterations do support - working and solution sets of different types - worksets that grow and shrink or are completely replaced in ea

Sorry for redundant post ... Hi all, We are working on an implementation of Frequent Subgraph Mining using Flink. At that, the "too few memory segments error" prevents the most promising solution. The problem is not specific for graphs, but all iterative problems where - working and solution se
