Aljoscha Krettek reassigned BEAM-253: ------------------------------------- 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]. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
