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 blocks data generation when there are sensitive schema changes. A sensitive schema change is a change that might result in data leakage. For example, a new column is added. Until you assign a generator to the column, the data is passed through as is to the output data. Before you can generate data with the new column, you must resolve the schema change.

• Structural does not block data generation when there are only notification schema changes. A notification schema change is a change that Structural can ignore during data generation. For example, a column is removed. Structural can ignore that column during data generation, until you are able to permanently resolve the schema change.

If this option is turned on, then if Structural detects any changes at all to the schema, then until you resolve the schema changes, data generation is blocked.
