title: How to exclude some of the Firebase database nodes from being persisted?
body: <pre><code>FirebaseDatabase.getInstance().setPersistenceEnabled(true);
  </code></pre>
  
  <p>This statement persists all the read and write operations in firebase database across the app restarts. But what i need to exclude some of my database nodes from being persisted?</p>
  
  <p>I am already storing the data in local database, and enabled the persistence only for the database write operations. Some of my queries are downloading a big amount of data for displaying some reports to the user and I want Firebase to exclude that query from being cached.</p>
  
  <p>Is there a preferred way to do this; or how can we persist only the database write operations? </p>
