What platforms are people trying to run Riak, Redis, and MongoDB on where a package is not available, or a compiler is not available?

add repository.... {apt-get,yum,brew,port} install {mongodb,riak,redis}

I see little benefit in compiling any of these products from source.

If you are on a host without a compiler you don't need a NOSQL db.

How do you figure?

I believe the insinuation is that if you're actually building a serious app that might actually benefit from NoSQL, then you should host it on a serious machine and not some shared hosting solution.

Basically conflating the idea that NoSQL is for 'real projects' and that only 'amateur hour' hosts have no compiler.

NoSQL is targeted at extreme performance. So, yes, it sounds like a reasonable assumption.

There are other advantages to NoSQL, like flexible data structure, and not having to squish your data into two incompatible data models.

Wouldn't you want to remove extraneous software eg. a compiler from a dedicated database host for security? (Yes, Python could be included in that as well)
