Most vehicles are rolling around on technology that was invented 10000 years ago. (Is that the same idea?)

That's interesting.

Could you point to a definition of "application" that has the word "team" in it?

Why should I waste time on a non-sequitur?

I'm continuously amazed when I hear about mongodb in use. Not over say postgres, I get that there are nosql advantages, but over literally any other nosql option. https://en.wikipedia.org/wiki/Poe%27s_law is the term you're looking for...

Which NoSQL would you prefer over mongo?

Sure. The most direct argument against that is that Postgresql jsonb is just non-relational data support in a first class relational DB, which is pretty great, so to an extend you get the best of both worlds, though I'm sure you can find a case where it's not quite optimal vs some nosql db. This talk is a pretty nifty perf overview: https://www.percona.com/live/e17/sessions/high-performance-j... That said, if you kno…

PostgreSQL JSONB doesn't have a dedicated driver though i.e. you can't do partial updates via the JDBC/ODBC drivers. Which means you can't use it for any big data/analytics use cases. MongoDB has fantastic client libraries e.g. Spark, Java.

Why wouldn't you be able to do partial updates with JDBC drivers?

Is it me..or does Mongo not seem as relevent and 'hip' as it once was... I mean I feel postgres is much more solid, and you can combine some of the aspects of document store via the json data types they added... of course I'm not really a DBA and don't have a lot of Mongo experience ... but personally I feel rdbms make more sense for growth/scaling..

Mongo is no longer as "hip", but it is slowly breaking into the enterprise as people learn the right use cases for it.

I still have trouble to find proper use cases for MongoDB that a more solid database couldn't handle.

They only guarantee consistency as long as you don't use them over a network, i.e. communications with the database are always reliable. But once you do use them over a network - CAP theorem comes in and forces you to either use something like two-phase commit or no promises of consistency. Which is the opposite of what his post implied, like there is CAP consistency with those databases. But there never was! Althoug…

Proper RDMS databases have two phase commit with transactions.....

Which ones? Traditional mainstream RDBMSs, like Mysql and Postgres don't use two-phase commit protocol. Obviously new distributed ones do it properly, but we are not talking about them.
