I’m really pleased to share the news that MongoDB has been acknowledged by the creators of the formidable Jepsen Test as demonstrating Data Safety, Correctness & Consistency. On February 7th 2017, Kyle Kingsbury, creator of Jepsen, published the results of his tests against MongoDB 3.4
His Conclusions are:
MongoDB has devoted significant resources to improved safety in the past two years, and much of that ground-work is paying off in 3.2 and 3.4.
MongoDB 3.4.1 (and the current development release, 3.5.1) currently pass all MongoDB Jepsen tests….These results hold during general network partitions, and the isolated & clock-skewed primary scenario.
