That's a poor argument and the comparison is just unfair. Actually, I am disappointed the author mentions Auroa but not Amazon DynamoDB. Half of the contenters are RDMS so it is totally unfair to suggest move off / move away from MongoDB because it lacks ACID. Furthermore the article really lacks technical comparison in depth. This is more of a notebook. Don't get me wrong I have used Mongo and I know it some of the common problems beginngers will find. As with every database there are gotchas. Postgres out of the box is great but doesn't mean it is the right fit for every problem and you still should fine tune your database.
- philliphaydon 9y agoDynamoDB is just not good. It has a document size limit, and throttling. It gets very expensive very quickly. And it's not fast. Writes are slow. And it's difficult to query.
- dataminer22 9y agoYes DynamoDB is indeed quite expensive - and increasingly so as data size and traffic grows. The whole point of distributed datastore like Dynomodb is to scale out massively by compromising on many database features and flexibility, but what's the point if it becomes so expensive at large scale?
