<p>I just flagged: <a href="https://stats.stackexchange.com/questions/299139/r-solution-for-high-performance-and-large-datasets">R solution for high performance and large datasets</a> for closing since it's quite obviously off-topic (I can't really see as instructions for setting up a Spark server from R Studio could be considered a statistical question). </p>

<p>However, I'm not sure if this can be considered a programming question either (it doesn't concern a specific language, but more correctly specific programs/cloud platforms, and I'm not sure how one would go around providing a sample test case). </p>

<p>Among the various options of the <code>close</code> flag, one can propose a new site to which the question would be migrated. Currently, three sites are allowed, Math Overflow, Stack Overflow and Math Exchange. Of course it wouldn't make sense to include <em>all</em> possible SE sites, but what about adding just Data Science SE? Questions like the one I just flagged look to me exactly the kind of question which would be on-topic there. </p>

<p>In my new position I work on and/or collaborate with people which work on problems very similar to that described by the OP,  and they're quite correctly (IMO) considered to be Data Science in the private sector.</p>

<p><strong>EDIT</strong>: I see that the same question has been flagged by other users. Regardless of where it will be migrated (or closed), I'm glad to see I'm not the only one who doesn't believe it's a valid CV question.</p>

<p><strong>EDIT2</strong>: in meantime, here is a question which has been (correctly, IMO) migrated to DS</p>

<p><a href="https://datascience.stackexchange.com/questions/22591/what-are-the-downsides-to-microsoft-azure-vs-scikit-learn-r">https://datascience.stackexchange.com/questions/22591/what-are-the-downsides-to-microsoft-azure-vs-scikit-learn-r</a></p>

<p>I wasn't involved in the migration, and surely a single case doesn't justify adding DS to the quick list.</p>
