Reintrospection is the process of synchronizing the TDV Server metadata representation of an introspected data source with the current state of the data source.

You can invoke reintrospection at any time, schedule it to occur periodically, use triggers, or call for it using a system API. Automated reintrospections can either just report on metadata differences or automatically reintrospect to synchronize TDV metadata to the current state of the resource.

Depending on the data source type (relational or file), all changes are detected, including the following:

Persistent reintrospection filters can be set to detect and incorporate new resources that meet the filter criteria during reintrospection. The filters are defined during introspection by the properties in the right side panel of the Data Source Introspection window.

Resources that were explicitly introspected remain introspected. Resources that were not selected during a previous introspection are not introspected, even if they happen to meet the criteria of a filter intended to find and introspect new resources.

The following sections describe the ways you can invoke reintrospection:
