Hello squirrels, this is a discussion thread to organize the Gelly component development for release 1.3 and discuss longer-term plans for the library.
I am hoping that with time-based releases, we can distribute the load for PR reviewing and make better use of our time, and also point contributors to "useful" tickets when they offer to help. I'm expecting the outcome of this discussion to be: (1) a set of open PRs to review and try merging for 1.3 (2) a set of open JIRAs to work-on before feature freeze (3) a set of JIRAs and PRs to reorganize/close (4) ideas on possible FLIPs Here's my initial take on things, i.e. features *I* see as important in the short-term. Feel free to add/remove/discuss: Release 1.3 ========== - Bipartite graph support. Initial support has been added, but there are unreviewed PRs <https://github.com/apache/flink/pulls?utf8=%E2%9C%93&q=is%3Apr%20is%3Aopen%20bipartite%20> and there is no Scala API yet. It would be nice to organize this feature, decide what functionality we need and what functionality is already covered by the Graph type and have proper bipartite support for 1.3. - Driver improvements, i.e. #3294 <https://github.com/apache/flink/pull/3294> - Algorithm improvements, #2733 <https://github.com/apache/flink/pull/2733> - Affinity Propagation algorithm. This one has been developed using a bulk iteration plan and needs a review. The PR is #2885 <https://github.com/apache/flink/pull/2885>. - Object reuse issues, FLINK-5890, FLINK-5891 - Vertex-centric iteration improvement, i.e. FLINK-5127 Roadmap ======== Regarding longer-term plans, I see the following issues as still being relevant from the existing roadmap [1]: - Extending the iteration functionality to support algorithms, more complex than value-propagation, e.g. with nested loops - Partitioning methods - Partition-centric iterations - Performance evaluation These two lists are by no means complete or final and the goal of this thread is to see what the community is interested in, whether these features / additions make sense to be worked on, or what features are missing. So, please provide your feedback! Cheers, -V. [1]: https://cwiki.apache.org/confluence/display/FLINK/Flink+Gelly
