Data which changes in Stacker is synced to your database immediately. When updates are made directly in the database, we automatically sync them into stacker every 15 minutes. We have recently released some features which allow us to sync the data every 5 minutes, and even faster in certain scenarios.
Fast data sync will be a paid add-on to your existing Stacker, priced at $79 monthly. We are still ironing out our automatic upgrade process. While we do, please contact support using the chat bubble or email us using the link below and we'll be happy to help you get set up.
