Subject [GitHub] incubator-quickstep pull request #281: Simplified the work order generation.
Date Thu, 24 Aug 2017 22:22:58 GMT
GitHub user zuyu opened a pull request:

    https://github.com/apache/incubator-quickstep/pull/281

    Simplified the work order generation.

    This PR revisited the work order generation process in the query execution engine, including
removal of a recursive method `processOperator`. This method does not introduce much performance
overside, while simplified the code base.
    
    Note that there are two `QueryManagerSingleNode` unit tests deletion due to the impossibility
in the real cases.
    
    Assigned to @jianqiao, and CC'ed @hbdeshmukh.
