If we refer to the CAP theorem, Mnesia sits on the CP side, rather than the AP side, meaning that it won't do eventual consistency, will react rather badly to netsplits in some cases, but will give you strong consistency guarantees if you expect the network to be reliable (and you sometimes shouldn't).
We start out with the TL;DR treatise: The mnesia database is not CP, nor AP. And it cannot be CA, because CA doesn’t make any meaningful sense. In short, it is broken with respect to the CAP theorem. https://medium.com/@jlouis666/mnesia-and-cap-d2673a92850
