-------------------------------------
Assignee: Aljoscha Krettek
> Unify Flink Operator Wrappers
> -----------------------------
>
> Key: BEAM-253
> URL: https://issues.apache.org/jira/browse/BEAM-253
> Project: Beam
> Issue Type: Improvement
> Components: runner-flink
> Reporter: Aljoscha Krettek
> Assignee: Aljoscha Krettek
>
> Right now, we have {{FlinkAbstractParDoWrapper}} with subclasses
> {{FlinkParDoBoundWrapper}} and {{FlinkParDoBoundMultiWrapper}} as well as
> {{FlinkGroupAlsoByWindowWrapper}}. They do essentially the same thing, but
> slightly differently. The first three are implemented as a
> {{FlatMapFunction}} while the latter is implemented as a {{StreamOperator}}
> (which is more low-level and gives access to state and timers and such).
> We should unify this into one wrapper. (With possibly a more concise name...)
> In the process of this we should also make sure that we always use a
> {{DoFnRunner}} via {{DoFnRunners.createDefault}}. This will help reduce bugs
> such as [BEAM-241].
