ASF GitHub Bot commented on BEAM-1467:

GitHub user vikkyrk opened a pull request:

    [BEAM-1467] dd cross-SDK implementations and tests of WindowedValueCoder

    Be sure to do all of the following to help us incorporate your contribution
    quickly and easily:
    - Tests for GlobalWindowCoder
    - Cross-sdk implementation / tests for WindowedValueCoder
    - Note: PaneInfo isn't supported in python SDK yet, so we hard code the value to 0x0F
which represents PaneInfo.NO_FIRING
     - [ ] Make sure the PR title is formatted like:
       `[BEAM-<Jira issue #>] Description of pull request`
     - [ ] Make sure tests pass via `mvn clean verify`. (Even better, enable
           Travis-CI on your fork and ensure the whole test matrix passes).
     - [ ] Replace `<Jira issue #>` in the title with the actual Jira issue
           number, if there is one.
     - [ ] If this contribution is large, please file an Apache

>            Priority: Minor
> Known window types include:
> * GlobalWindow
> * IntervalWindow
> * WindowedValueCoder
> Standardizing the name and encodings of these windows will enable many more pipelines
to work across the Fn API with low overhead.
