Advanced workspace overrides
For self-hosted instances, Structural provides environment settings to configure features that include:
Consistency across runs and databases
Data generation performance
The Advanced Workspace Overrides section of the workspace details view allows you to override those environment settings for an individual workspace.
For example, the environment setting TONIC_TABLE_PARALLELISM
determines the number of tables that Structural processes simultaneously. You can then override that value within individual workspaces.
The workspace overrides are available on both self-hosted instances and on Structural Cloud.
Configuring the overrides
To display the available override settings, expand Advanced Workspace Overrides.

Enabling and setting an override
For information on how to configure the statistics seed, go to Overriding the Structural seed value for a workspace.
For other settings, to enable the override and set the override value:
Toggle the setting to the on position.

Set the value.
Removing an override
To remove the override, toggle the setting to the off position.
Available overrides
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.
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.
Data generation performance settings
Structural provides environment settings to manage data generation performance. For example, these settings include configuration for parallel processing.
From Advanced Workspace Overrides, you can override some of these data generation performance settings for an individual workspace.
Data encryption and decryption keys
To use Structural data encryption, you must provide encryption and decryption keys.
You use the Override Data Decryption Key and Override Data Encryption Key settings to override the Structural-wide keys that are provided in the environment settings.
Destination database schema creation
Some data connectors allow you to configure whether you provide the schema for the destination database. For more information, go to related information for Databricks, MySQL, Oracle, Snowflake on AWS, Snowflake on Azure, and SQL Server.
From Advanced Workspace Overrides, you can override the instance-wide configuration.
