Ahmet Altay commented on BEAM-6858: ----------------------------------- PR #9275 is resulting in test issues (https://issues.apache.org/jira/browse/BEAM-8102). Could you look at that please? > Support side inputs injected into a DoFn > ---------------------------------------- > > Key: BEAM-6858 > URL: https://issues.apache.org/jira/browse/BEAM-6858 > Project: Beam > Issue Type: Bug > Components: sdk-java-core > Reporter: Reuven Lax > Assignee: Shehzaad Nakhoda > Priority: Major > Time Spent: 8h 50m > Remaining Estimate: 0h > > Beam currently supports injecting main inputs into a DoFn process method. A > user can write the following: > @ProcessElement public void process(@Element InputT element) > And Beam will (using ByteBuddy code generation) inject the input element into > the process method. > We would like to also support the same for side inputs. For example: > @ProcessElement public void process(@Element InputT element, > @SideInput("tag1") String input1, @SideInput("tag2") Integer input2) > This requires the existing process-method analysis framework to capture these > side inputs. The ParDo code would have to verify the type of the side input > and include them in the list of side inputs. This would also eliminate the > need for the user to explicitly call withSideInputs on the ParDo. > -- This message was sent by Atlassian Jira (v8.3.2#803003)
