MongoDB Fault Tolerance - Broken by Design

Emin Gün Sirer:

So, MongoDB is broken, and not just superficially so; it’s broken by design. If you’re relying on its fault tolerance,a you’re probably using it wrong.

He’s not the first to write about some of the critical issues in MongoDB. Every once in a while, there has been at least one post detailing one of these. But none of them stopped MongoDB’s adoption. Why? My only explanations are that:

  1. these posts are not reaching enough people;
  2. MongoDB is used mostly for simple scenarios where the occurance of such errors can be ignored
  3. those using MongoDB for more complicated scenarios have developed internal, application specific workarounds
