  • Zero downtime during upgrades and scaling out system (such as zero seconds downtime, while app still runs)

  • Highly Scalable with Terabytes of data with high performance and low cost with shards

  • Automatic Replica Set member take-over in case of failing primary, with automatic recovery for returning hosts.

  • Automatic promotion to primary and de promotion for any member of a replica set based on performance and latency.

  • Journaling, allows safe recovery in case of hard-disk failure.

  • Strong consistency, "Afford to loose data" in mongoDB is myth. Data is not lost, it's only not persisted due to failures on the developers code.

  • When Sharding is not feasible, different Documents (rails models) can be on different Replica sets (different database or set) altogether, since there are no joins in Mongo.

  • Background indexes.
