Data generation settings

Blocking data generation for all schema changes

Most workspaces that connect to a database have a Block data generation if schema changes detected toggle. The setting is usually in the Source Settings section.

By default, the option is turned off. When the option is off, Structural only blocks data generation when there are conflicting schema changes. Structural does not block data generation when there are non-conflicting schema changes.

If this option is turned on, then if Structural detects any changes at all to the schema, then data generation is blocked until you resolve the schema changes. For more information, go to Viewing and resolving schema changes.

Workspace statistics seed for cross-run consistency

For generators where consistency is enabled, a statistics seed enables consistency across data generation runs. The Structural-wide statistics seed value ensures consistency across both data generation runs and workspaces.

You use the Override Statistics Seed setting to override the Structural-wide statistics seed value. For workspaces that connect to a database, the setting is under Destination Settings. For a file connector workspace, the setting is under Output Location.

You can either disable consistency across data generations, or provide a seed value for the workspace. The workspace seed value ensures consistency across data generation runs for that workspace, and across other workspaces that have the same seed value.

For details about using seed values to ensure consistency across data generation runs and databases, go to Enabling consistency across runs or multiple databases.
