Joins are overrated anyway, who needs them?

Wait, no authentication? That sounds risky!

Omitted multi-statement transactions for sure.

I thought they had some form of transactions?

Definitely no joins in MongoDB!

I feel like multi-statement transactions are also omitted for scalability reasons, but I need to double-check my notes on that.

I’m a bit confused about authentication being listed here. I thought that was still a feature in MongoDB, but maybe it’s not as crucial for scalability?

I remember practicing a question about MongoDB's design choices, and I think joins were definitely one of the features they left out.

I think MongoDB omits joins to achieve horizontal scalability, but I'm not entirely sure about multi-statement transactions.

Wait, is authentication one of the features that was omitted? I'm a little confused on how that relates to horizontal scalability. I'll have to think this through carefully.

Okay, I've got this. MongoDB deliberately omits features like multi-statement transactions and joins in order to scale more easily across multiple servers. I'm confident I can get this one right.

Hmm, I remember learning about how MongoDB sacrifices some features of relational databases in order to achieve better scalability. I think the answer has to do with things like transactions and joins, but I'll need to double-check.

This question seems straightforward, but I want to make sure I understand the key differences between relational databases and MongoDB. I'll need to review my notes on horizontal scalability.

As someone who's been on a MongoDB binge lately, I can confirm that A), B), and C) are all MIA in that database. Gotta keep it simple, stupid!

B) Joins? More like 'B) Byes' in MongoDB! Amirite?

I also believe multi-statement transactions were omitted for scalability reasons.

I'm going with B) and C) here. Authentication is a must-have, but joins just slow things down when you're dealing with big data.
AL

I'd say A) and B) were both deliberately left out. MongoDB is all about that NoSQL life, ya know?
AN

Totally, A) and B) were deliberately omitted for horizontal scalability.
ST
Stacey

Yeah, MongoDB is definitely all about that NoSQL life.

A) Multi-statement transactions
HO
Holley

Yes, that's correct. Joins can be expensive in terms of performance.
DE
Delfina

Definitely B) Joins. MongoDB sacrifices joins for horizontal scalability, so that's a key feature that was omitted.
