By default, during each data generation job, Structural creates the database schema for the destination database tables, then populates the database tables based on the workspace configuration.
If you prefer to manage the destination database schema yourself, then set the environment setting TONIC_SNOWFLAKE_SKIP_CREATE_DB to true. You can add this setting manually to the Environment Settings list on Structural Settings.
The environment setting applies to both Snowflake on AWS and Snowflake on Azure.
When TONIC_SNOWFLAKE_SKIP_CREATE_DB is true, then Structural does not create the destination database schema. Before you run data generation, you must create the destination database with the full schema.
During data generation, Structural deletes the data from the destination database tables, except for tables that use Preserve Destination mode. It then populates the tables with the new destination data.
