Trigger Refresh Jobs
Composer 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
Composer 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.
Refresh Type | Trigger | Activities |
---|---|---|
Source Refresh | An initial connection to a data source is saved. See Define a Data Source Configuration. | The Composer 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 Edit a Data Source Configuration. | ||
The scheduled refresh time (set on the Refresh tab in the data source configuration) occurs. See Set Up a Data Source Refresh Job. | ||
Field Refresh | 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 Review Refresh Jobs.
