Template variables and the Databricks data source

Instead of hard-coding details such as server, application, and sensor names in metric queries, you can use variables. Grafana displays these variables in drop-down select boxes at the top of the dashboard to help you change the data displayed in your dashboard. Grafana refers to such variables as template variables.

After creating a variable, you can use it in your Databricks queries by using Variable syntax. For more information about variables, refer to Templates and variables.

Create Databricks query variables

To add a new Databricks query variable, refer to Add a query variable.

To create a query variable for Databricks, write a SQL query that returns your desired variable options:

SQL Copy

SELECT DISTINCT region FROM sales_data ORDER BY region

This query creates a drop-down with all unique regions from the sales_data table. You can enable multi-value selection or include an “All” option in the variable settings.
