I think that C is the strong solution, getting the ingest really strong is going to lower barriers to adoption. Doing it in Python will open up the ingest portion of the project to include many more developers.
Before it comes up I would like to throw the following on the pile... Major python projects django/flash, others are dropping 2.x support in releases scheduled in the next 6 to 8 months. Hadoop projects in general tend to lag in modern python support, lets please build this in 3.5 so that we don't have to immediately expect a rebuild in the pipeline. -Vote C Thanks Nate Austin On Fri, Apr 14, 2017 at 8:52 AM Alan Ross <[email protected]> wrote: > I really like option C because it gives a lot of flexibility for ingest > (python vs scala) but still has the robust spark streaming backend for > performance. > > Thanks for putting this together Nate. > > Alan > > On Fri, Apr 14, 2017 at 8:44 AM, Chokha Palayamkottai < > [email protected]> wrote: > > > I agree.
