These articles are not targeted at you indeed but to the thousands of companies trying to setup a massive architecture to process 3GB of data per year.
All these big data solutions are still necessary of course, it's just not for everyone.
Agreed they are tools designed to fill a niche. This doesn't make them bad, or uneccessary, just specialized. A spanner drive screw isn't worse than a hex drive, it's just designed for a different more specific use case.
Really this just goes to show how impressive RDMSs like Postgres are. There's nothing out there that's drastically better in the general case. So alternative database systems tend to just nibble around the edges.
My rule of thumb is always try to implement it using a relational model first, and only when that proves itself untenable, look into other more specialized tools.
Yeah but the whole cloud paradigm is predicated on big data, so large actors are pushing it where it makes no sense, and it makes everyone less effective. Not more.
Ever notice how with cloud it's actually in the interest of cloud providers to have the worst programmers, worst possible solutions for their clients ? Those will maximize spend on cloud, which is what these companies are going for.
Of course, they hold up the massive carrot of "you can get a job here if you ...".
