Key Takeaways Rollbacks in MongoDB are triggered by disruptions in the replication process due to primary node crashes, network partitions, or other failures, which can lead to substantial data loss and inconsistencies. This process initiates recording and tracking, ensuring a more thorough approach than the default, low-level options.
