Allow custom convergence criterion in delta iterations As discussed in the Jira issue, this PR contains the following changes: 1. use `TaskConfig.setConvergenceCriterion()` to set the custom, user-defined convergence criterion (like in the case of bulk iteration) 2. add a new method `TaskConfig.setDefaultConvergeCriterion()` to handle the default empty workset convergence â3. check both criteria in `IterationSynchronizationSinkTask.checkForConvergence()â` 4. expose the custom convergence criterion in `DeltaIteration` It also contains some minor cleanup and corresponding changes in the `CollectionExecutor`. The iteration docs already state that custom convergence is possible, so no update needed there ;) You can merge this pull request into a Git repository by running: $ git pull https://github.com/vasia/flink flink-3888 Alternatively you can review and apply these changes as the patch at: https://github.com/apache/flink/pull/2606.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #2606 ---- commit 41327034ae57d99fdde74bf24838d19b5aee31f3 Author: vasia <va...@apache.org> Date: 2016-10-05T11:49:20Z [FLINK-3888] allow registering a custom convergence criterion in delta iterations commit e7ffc368f8542d3afe823b86c23e91379a03e21b Author: vasia <va...@apache.org> Date: 2016-10-05T12:06:47Z [FLINK-3888] cleanups in iterations and aggregators code commit 3b1a5e55686f665b1c1bb90943b0f853e71eae82 Author: vasia <va...@apache.org> Date: 2016-10-06T20:25:43Z [FLINK-3888] add delta convergence criterion in the CollectionExecutor commit 9f41af544eecae0c37ae9470f4ff26f19b5dbdc0 Author: vasia <va...@apache.org> Date: 2016-10-06T21:00:38Z [FLINK-3888] add ITCases for delta custom convergence ---- --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.
