(Even better, enable Travis-CI on your fork and ensure the whole test matrix passes). - [ ] Replace `<Jira issue #>` in the title with the actual Jira issue number, if there is one. - [ ] If this contribution is large, please file an Apache [Individual Contributor License Agreement](https://www.apache.org/licenses/icla.txt). --- This DoFnRunner wraps an existing DoFnRunner and provides a method, processElementInReadyWindows, which returns a list of WindowedValues that could not be processed due to requiring a SideInput that is not ready. You can merge this pull request into a Git repository by running: $ git pull https://github.com/tgroh/incubator-beam ippr_pushback_do_fn_runner_impl Alternatively you can review and apply these changes as the patch at: https://github.com/apache/incubator-beam/pull/258.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 #258 ---- commit 6110210d2c933ad87f165d8e1196718c80cb6794 Author: Thomas Groh <tg...@google.com> Date: 2016-04-28T00:26:13Z Add PushbackDoFnRunner This DoFnRunner wraps an existing DoFnRunner and provides a method, processElementInReadyWindows, which returns a list of WindowedValues that could not be processed due to requiring a SideInput that is not ready. ---- > DirectPipelineRunner: support for unbounded collections > ------------------------------------------------------- > > Key: BEAM-22 > URL: https://issues.apache.org/jira/browse/BEAM-22 > Project: Beam > Issue Type: Improvement > Components: runner-direct > Reporter: Davor Bonaci > Assignee: Thomas Groh > > DirectPipelineRunner currently runs over bounded PCollections only, and > implements only a portion of the Beam Model. > We should improve it to faithfully implement the full Beam Model, such as add > ability to run over unbounded PCollections, and better resemble execution > model in a distributed system. > This further enables features such as a testing source which may simulate > late data and test triggers in the pipeline. Finally, we may want to expose > an option to select between "debug" (single threaded), "chaos monkey" (test > as many model requirements as possible), and "performance" (multi-threaded). > more testing (chaos monkey) > Once this is done, we should update this StackOverflow question: > http://stackoverflow.com/questions/35350113/testing-triggers-with-processing-time/35401426#35401426 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
