Following the technical vision Frances sent, and following the previous document I wrote on the spark runner gaps, I'm attaching a suggested technical vision to the Spark runner.
I tried to be inline with the project's technical vision both in timeline, and in document style. I suggest that once the ASF Wiki is up, we'll have roadmap for runners as well. Thanks, Amit https://docs.google.com/document/d/1y4qlQinjjrusGWlgq-mYmbxRW2z7-_X5Xax-GG0YsC0/edit?usp=sharing
