Customizing Auto Refresh in Tableau

Best Practices for Auto Refresh in Tableau
- Consider Performance Implications: Before enabling auto refresh, assess the performance impact on your Tableau workbook, especially if you are working with large datasets.
- Use Incremental Data Refresh: If possible, use incremental data refresh to reduce the performance impact of auto refresh. This technique only refreshes the data that has changed since the last refresh, minimizing the load on your system.
- Schedule Refreshes Wisely: Schedule data refreshes during off-peak hours or when there is less user activity to minimize the impact on performance.
- Monitor Your Data Sources: Regularly monitor your data sources to ensure that they are healthy and providing accurate data. This will help you identify any issues that may affect the auto refresh process.
Troubleshooting Auto Refresh Issues in Tableau
If you encounter issues with auto refresh in Tableau, here are some troubleshooting tips:
- Check Data Source Connectivity: Ensure that your data source is properly connected and accessible.
- Verify Refresh Settings: Confirm that the auto refresh settings are correct, including the refresh interval and schedule.
- Disable Other Data Sources: If you have multiple data sources in your Tableau workbook, disable all but the one you want to refresh automatically.
- Contact Tableau Support: If you are unable to resolve the issue on your own, contact Tableau Support for assistance.
