## Parameters


<ul className="method-list-group">
  
<li className="method-list-item">
  <h4 className="method-list-item-label">
    <span className="method-list-item-label-name">
      subscription
    </span>
    <span className="method-list-item-label-badge required">
      required
    </span>
    <span className="method-list-item-validation">
      <code>RealtimeSubscription</code>
    </span>

</ul>


## Notes

- Removing subscriptions is a great way to maintain the performance of your project's database. Supabase will automatically handle cleanup 30 seconds after a user is disconnected, but unused subscriptions may cause degradation as more users are simultaneously subscribed.
