After being introduced to the MongoDB stale read issue in 2015 [1] we abandoned MongoDB and never looked back. Anyone knows if this is resolved in the latest versions?

- travisp 9y agoIt got significantly better in 3.4 -- this analysis claims that the issues were finally resolved in 3.4 (although they were in the RC) https://jepsen.io/analyses/mongodb-3-4-0-rc3 https://jepsen.io/analyses/mongodb-3-4-0-rc3
- bastijn 9y agoThanks. Seems they did some good work indeed. Though it takes time before they get back the trust they lost over this.

Edit: Also looks like Kyle saved for the next time testing of server crashes and restarts which is another difficult problem to handle when performance is important.
