It’s not that switching to NoSQL is a bad idea necessarily; there are some things that RDBMS software can’t do as well as a more dedicated solution. But, if you think that switching to NoSQL will just let you hand-wave away all of the challenges of running a database, you are terribly misguided. If you’re a DBA and you are worried about a future with NoSQL, take heart; study your product less and focus on these key architectural design points more. Those skills are critical now, and they will remain so in the future, NoSQL or not.
