System Resources
Enterprise Data Catalog creates the following system resources to perform various internal jobs when you enable the Catalog Service:
- DataDomain
- Internal system job that is auto-scheduled to run every 45 minutes. The scanner synchronizes the data domains between the Model repository and catalog.
- DataDomainPropagation
Internal system job that is auto-scheduled to run at regular intervals. The scanner uses the inferred similar columns to propagate the example-based data domains to other similar columns. The scanner also identifies and propagates the business terms to other similar columns.
- DomainUsers
Internal system job that synchronizes Informatica domain users between the Informatica domain and catalog.
- SimilarityDiscovery
- Internal system job that discovers similar columns based on column name, column data pattern, unique values, and value frequency in the resource.
You can configure the following settings for the resources based on your requirements similar to how you configure any other resources that you create:
- •Modify the memory required to run the resource.
- •Assign custom attributes to the resource.
- •Modify the schedule for the resource.
Note: You can modify the description for the scanners, but you cannot modify the name or resource type details for system resources.
