title: How to set up Superset config for caching
body: <p>Right now, I am working on Airbnb Superset project for working purpose.</p>
  
  <p>I know Superset supports cache (by Flask-Cache), but I got stuck when I set up the configuration.</p>
  
  <p>My config.py file looks like this:</p>
  
  <pre><code>    CACHE_DEFAULT_TIMEOUT = 60 * 60 * 24
      CACHE_CONFIG = {'CACHE_TYPE': 'filesystem',
                  'CACHE_DIR': os.path.join(BASE_DIR, '/temp'),
                  'CACHE_DEFAULT_TIMEOUT': CACHE_DEFAULT_TIMEOUT,
                  }
  </code></pre>
  
  <p>But after I re-start the server, there is no different.</p>
  
  <p>Does anyone know how to set up? Thanks.</p>
