Subject [jira] [Commented] (BEAM-37) Run DoFnWithContext without conversion to vanilla DoFn
Date Fri, 15 Jul 2016 17:30:20 GMT

    [ https://issues.apache.org/jira/browse/BEAM-37?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15379728#comment-15379728
] 

Ben Chambers commented on BEAM-37:
----------------------------------

Notes on remaining tasks to complete this:

1. Modify DoFnRunner to allow executing a DoFnWithContext
2. Modify any runner specific code to use DoFnRunner when a DoFnWithContext is received.
3. Remove wrapping of DoFnWithContexts from DataflowRunner (and others) to use the modified
code above.

> DoFnWithContext is an enhanced DoFn where annotations and parameter lists are inspected
to determine whether it accesses windowing information, etc.
> Today, each feature of DoFnWithContext requires implementation on DoFn, which precludes
the easy addition of features that we don't have designs for in DoFn.
