Unloading data In Ember Data

Would it be a correct statement that Ember Data never automatically unloads data from its cache? I am curious because I am intending to build a client side app with large data sets, and I would like to unload records when they are no longer needed. And I haven’t found much info about people doing this besides this S.O. answer: ember.js - How to prevent caching in Ember Data - Stack Overflow.

Is this concept something I should worry about or is there maybe something in the Ember core that covers this? I just want to make sure I understand the Ember Data philosophy, because it’s possible I am missing something obvious here because I am quite new to Ember.

There was a Soundcloud post I read a while back that gave some good insight as well Building The Next SoundCloud | SoundCloud Backstage Blog (Letting go section).

Thanks.
