Grafana Cloud has introduced query caching, a feature designed to improve performance and reduce costs for popular dashboards by storing query results for faster retrieval, thereby decreasing load times and API request costs. This feature is particularly beneficial during high-traffic events, such as Black Friday and Cyber Monday, by lowering total wait times and operational costs significantly. To enable query caching, users must activate it in the data source settings, with support available for various data sources including CloudWatch, Google Cloud Monitoring, and MySQL, among others. Once enabled, users can adjust the Time to Live (TTL) settings to control data refresh rates, with the default set to 5 minutes, while specific dashboard panels can be set to refresh more frequently if needed. Query caching is accessible to all Grafana Cloud Pro and Advanced users, with a 14-day free trial available for new users, and further information and support can be accessed through the Grafana Cloud Community Slack.
