Triggering Refresh Jobs
Zoomdata maintains data source metadata and, optionally, a cached result set of the data from the data store for each data source configuration you define. When you initially connect to your data store using a data source configuration, a sampling of the data is collected to determine:
- Distinct values for all fields with attribute field types
- The minimum and maximum values for all fields with number or integer field types
Zoomdata administrators can define refresh jobs for this cached data. The following table identifies the types of refresh jobs that are currently supported, the triggers for the jobs, and the activities that occur when the job is run.
An initial connection to a data source is saved. See Defining a Data Source Configuration.
|The Zoomdata cache is cleared and the minimum and maximum values for non-attribute fields and distinct values for attribute fields are refreshed.|
|Changes to the Tables or Fields tab in the data source configuration are saved. See Editing a Data Source Configuration.|
|The scheduled refresh time (set on the Refresh tab in the data source configuration) occurs. See Setting Up a Data Source Refresh Job.|
One of the refresh options on a data source configuration's Fields Tab tab is selected.
|The minimum and maximum for non-attribute fields and distinct values for attribute fields are refreshed.|
The status of refresh jobs can be reviewed on the Console of Refreshing Jobs. See Reviewing Refresh Jobs.
