Data freshness
After opening a dataset, you can see the Freshness in the Data quality area. The data freshness indicates the last update of the data source.
資訊備註The data freshness is only available for datasets created in Qlik Talend Data Integration.
The time depends on the update method:
- The Change Data Capture (CDC) method: The time corresponds to the last event on the data source. For example, the data source has been updated at 9:00 AM. The pipeline runs at 10:00 AM. You open the overview at 11:00 AM. The data freshness is 2 hours ago.
- The Reload and compare method: The time corresponds to the last run. For example, the data source has been updated at 9:00 AM. The pipeline runs at 10:00 AM. You open the overview at 11:00 AM. The data freshness is 1 hour ago.
Computing the profile or the data quality does not impact the data freshness.
The data freshness is available in the dataset overview only. The Last modified column in the Catalog tab indicates the last modification on the dataset itself, renaming it or editing the description for instance.
