Thanks for posting this to HN (I'm the post author).
There are two posts:
1) the link you posted. It looks at the application as a whole, not really at the datastore alone.
2) Another one on the big data store themselves, and more generally of the different definitions of 'availability'. It's here http://blog.thislongrun.com/2015/04/cap-availability-high-av...
I will update the posts to make this clearer. As well, it's a series and these posts are the most complex of the series :-). Many points are more detailed in the previous posts.
