You can purge obsolete objects from a catalog source.
When you configure or run a catalog source, you can choose to deprecate objects that are deleted from a source system. If you delete objects from the source system or make changes to the filter, the objects imported into the catalog before the change move to the Obsolete lifecycle in the catalog. You can purge obsolete objects from a catalog source. This permanently deletes all objects with the Obsolete lifecycle status, along with associated enrichments, from the catalog.
1Go to the Explore page in Metadata Command Center.
2Select Catalog Sources from the menu.
3From the list of catalog sources, search for the catalog source from which you want to purge obsolete objects.
4Click the Action menu, and select Purge Obsolete Objects.
A warning message appears on the page.
5Click Yes to confirm.
A confirmation message appears on the page and the purge job starts. You can monitor the status of the job on the Monitor page. If the job succeeds, all obsolete objects present in the catalog source disappear from the catalog.
Note:
If the job fails, some obsolete objects might remain in the catalog. To remove the remaining obsolete objects, run the purge job again.
