MongoDB seems to have experienced a rather exaggerated version of the hype cycle. But it also seems like, at this point, the technology is well into the "slope of enlightenment" phase of its hype cycle, and may even have reached the "plateau of productivity". A lot of that is fueled by MongoDB's own efforts - they took the complaints about reliability quite seriously. Case in point: This series of Jepsen tests that they've been funding.
