It’s actually not correct that MongoDB is not ACID-compliant. On the contrary, MongoDB is ACID-compilant at the document level.
Any update to a single document is
- Atomic: it either fully completes or it does not
- Consistent: no reader will see a “partially applied” update
- Isolated: again, no reader will see a “dirty” read
- Durable: (with the appropriate write concern)
What MongoDB doesn’t have is transactions – that is, multiple-document updates that can be rolled back and are ACID-compliant.
Multi-document transactions, scheduled for MongoDB 4.0 in Summer 2018*, will feel just like the transactions developers are familiar with from relational databases – multi-statement, similar syntax, and easy to add to any application.
