Date Sat, 27 May 2017 08:13:04 GMT


Manu Zhang reassigned GEARPUMP-316:

    Assignee: Manu Zhang

> Don't enforce groupBy after window
> ----------------------------------
>                 Key: GEARPUMP-316
>                 URL:
>             Project: Apache Gearpump
>          Issue Type: Sub-task
>          Components: streaming
>            Reporter: Manu Zhang
>            Assignee: Manu Zhang
> Return a normal Stream instead of WindowStream on window function. Window function defines
a boundary (window) for elements and the following operations should fall in corresponding
boundaries. The boundary should not change until a new window function is defined. The default
boundary is the {{GlobalWindows}}.
> This means there will be a window context for each underlying task. Elements are emitted
in terms of the trigger semantics.
