Enable Data Sharpening and Configure Its Defaults
To enable and configure Data Sharpening for a data source configuration, you need to enable the time settings in the data source's settings page. Specifically, a playable time field must be specified in the Global Default Settings on the Visuals tab of the data source configuration. However, Cloudera Impala data sources require additional configuration as described in Enable Data Sharpening for Cloudera Impala Data Sources.
To configure Data Sharpening in a data source configuration:
- Log into Composer (either as an administrator or as a user who has been assigned to a group with data source management privileges).
In the table on the Sources page, locate and select the data source configuration you want to edit.
Select the Global Settings tab. The time bar, search, and Data Sharpening settings for the data source appear.
Make sure Time Bar is enabled to access Data Sharpening settings. If Time Bar is disabled, you can't configure Data Sharpening settings. For more information about time bar default settings, see Configure Time Bar Defaults.
Slide the Prefer Sharpening switch to the right to enable Data Sharpening for the data source.
Optionally, use the Max Queries slider to specify the maximum number of queries used for Data Sharpening. The default maximum is 10 queries.
When your changes are complete, select Save Settings to save your changes.
