Michael Stonebraker has an interesting set of conclusions in his assessment of the MapReduce vendor market in 2015 from the "Dataflow" chapter here:
"- Just because Google thinks something is a good idea does
not mean you should adopt it.
- Disbelieve all marketing spin, and figure out what benefit
any given product actually has. This should be especially
applied to performance claims.
- The community of programmers has a love affair with “the
next shiny object”. This is likely to create “churn” in your
organization, as the “half-life” of shiny objects may be quite
short."
