Study Notes
Data Refresh Intervals for Dashboards
- Dashboards: Set refresh intervals (defaults to never).
- Reports: No automatic refresh, but pages are cached.
- SQL Query Results: Cached with a 15-minute refresh rate.
Factors Affecting Refresh Intervals
1. Data Freshness
- Data Sensitivity: Time-sensitive data (e.g., stock prices, real-time sales) requires frequent refreshes.
- Data Volume: Larger datasets may require longer refresh intervals to prevent performance issues.
- Data Source Limitations: Limits on how often data sources can be queried influence refresh strategies.
2. User Needs
- Frequency of Use: Frequent use by decision-makers benefits from shorter intervals.
- Level of Detail: High-level summaries need less frequent updates than detailed dashboards.
- User Preferences: Allow users to manually refresh or adjust intervals.
3. System Performance
- Server Load: Frequent refreshes increase server load, especially with complex queries or large datasets.
- Network Latency: Network delays affect data retrieval and processing time.
- Dashboard Complexity: More complex dashboards with numerous visualizations may require longer refresh rates.
4. Resource Utilization
- Database Queries: Frequent queries strain database resources.
- Data Processing: Data transformation and processing consume significant resources.
5. Security and Privacy
- Data Exposure: Frequent refreshes may expose sensitive data to unauthorized access.
- Security Protocols: Protect data during transmission and processing with security measures.
Best Practices for Refresh Intervals
- Dynamic Refresh: Update data only when users interact, reducing unnecessary overhead.
- Caching: Store frequently accessed data to improve performance and reduce data source load.
- Optimized Queries: Write efficient SQL queries to reduce execution time.
- Load Balancing: Distribute traffic across multiple servers to handle increased load.
- User Notifications: Inform users of data updates or errors.
- Performance Monitoring: Continuously monitor dashboard performance and adjust refresh intervals as needed.
