This provides the #shouldOverride method to determine if a PTransform
override should be applied, based on the original PTransform.
This permits overrides that are applied conditionally (such as
shard-controlled writes).
For all existing overrides, this value is equal to true.
This is used in (written, but unpublished) overrides for TextIO.Write and
AvroIO.Write, so the write can be overridden in terms of sharded writes.
You can merge this pull request into a Git repository by running:
$ git pull https://github.com/tgroh/incubator-beam

> 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
