title: Android Paging library - releasing cached data
body: <p>I read a few resources on <a href="https://developer.android.com/topic/libraries/architecture/paging/" rel="nofollow noreferrer">Android Paging library</a>. While the topic sounds great, I'm unable to understand how and when the resources are released from DataSource in <a href="https://developer.android.com/topic/libraries/architecture/images/paging-library-data-flow.webp" rel="nofollow noreferrer">DataSource+Network scenario</a>.</p>
  
  <p>What if I have a very large list (lets say hundreds of MBs) and I need to keep the storage footprint low? Who and when will cleanup unused rows from underlying data source?</p>
