The DynamoDB Paper

You seem to think MongoDB is eventually consistent. MongoDB is designed as strongly consistent database. You can choose to query a secondary and that will be eventually consistent but that is not the default behaviour.

I must have clarified, what I mean by strong consistency is that you have transactional support (2 phase commit). MongoDb is atomic, meaning every single document is strongly consistent. However, I stand corrected. They have introduced transactions as of 4.2.

I believe multi document transactions offer only causal consistency?
