Good article but I'm still struggling to understand CAP in practice.
In general, the whole distributed system will include some kind of database and some kind of application servers. What would AP mean in this context? That application server nodes are able to respond meaningful (ie non failing) responses even if they are unable to communicate with the DB? Wouldn't that require every application node to have a whole local copy of the data it requires to work?
