One slightly concerning thing about this is the table at the end dictating what popular NoSQL DBs do is populated by, and here I quote - "The methodology used to identify the specific system properties consists of an in-depth analysis of publicly available documentation and literature on the systems. Furthermore, some properties had to be evaluated by researching the open-source code bases, personal communication with the developers as well as a meta-analysis of reports and benchmarks by practitioners."
Which looking at the table, doesn't seem to include Aphyr's work (Jepsen), so much of what is being said may in fact be wrong. I'd prefer a chart populated from that (though admittedly such a chart would largely be "undefined", "inconsistent", etc).
