Everytime i read one of those post (or other about mongodb failures), i keep thinking about this talk <a href="http:&#x2F;&#x2F;youtu.be&#x2F;4fFDFbi3toc" rel="nofollow">http:&#x2F;&#x2F;youtu.be&#x2F;4fFDFbi3toc</a><p>And why noone tried to repeat their strategies for building a robust db system : start by building an extremely robust failure simulation and testing facility. Then build your product.<p>Actually, i think what those guys at foundationdb did was so exceptional, that by buying the company and killing the product, Apple harmed the software industry for the next 10 years. The fact the foundationdb is mentionned in OP as the only distributed db system one could recommend makes me more confident making that statement.
