We have just left Parse.com due to restrictions on the number of API requests and limitations on joining tables. Having now read extensively about denormalising data we have learnt about dealing with large datasets and not using joins. We are trying to decide whether to move to a noSQL DB or use mySQL which is what we all know (and love).
So the question is: If building an app with an anticipated large growth rate should we start out with noSQL and go through a steep learning curve now or build it faster on mySQL and load test to prove it will cope?
Advise from anyone who has been through this experience gratefully received.
