After you select the connector type, you configure:
Where to find the source data
Where to write the data generation output
For data connectors that connect to a database, the Source Settings section provides connection information for the source database.
You cannot change the source data configuration for a child workspace.
For information about the source connection fields for a specific data connector, go to the workspace configuration topic for that connector type.
For data connectors that support upsert, the workspace configuration includes an Upsert section to allow you to enable and configure upsert. Upsert adds and updates rows in the destination database, but keeps all other existing rows intact.
If you enable upsert, then you cannot write output to an Ephemeral database or to a container repository. You must write the output to a destination database.
For more information, go to Enabling and configuring upsert.
For data connectors that connect to a database, the Destination Settings section provides information about where and how Structural writes the output data from data generation.
Depending on the data connector type, you might be able to write to either:
Destination database - Writes the output data to a destination database on a database server.
Ephemeral snapshot - Writes the output data to a Tonic Ephemeral user snapshot.
Container repository - Writes the output data to a data volume in a container repository.
When you write the output to a destination database, the destination database must be of the same type as the source database.
Structural does not create the destination database. It must exist before you generate data.
In Destination Settings, you provide the connection information for the destination database. For information about the destination database connection fields for a specific data connector, go to the workspace configuration topic for that connector type.
If available, the Copy Settings from Source allows you to copy the source connection details to the destination database, if both databases are in the same location. Structural does not copy the connection password.
If Ephemeral supports your workspace database type, then you can write the destination data to a snapshot in Ephemeral. For data larger than 10 GB, this option is recommended instead of writing to a container repository.
From Ephemeral, you can use the snapshot to start new Ephemeral databases.
For more information, go to Writing output to Tonic Ephemeral.
Some data connectors allow you to write the transformed data to a data volume in a container repository instead of to a database server.
You can use the resulting data volume to create a database in Tonic Ephemeral. If you do plan to use the data to start an Ephemeral database, and the size of the data is larger than 10 GB, then the recommendation is to write the data to an Ephemeral user snapshot instead.
For more information, go to Writing output to a container repository.
When you provide connection details for a database server, Structural provides a Test Connection button to test the connection, and verify that Structural can use the connection details to connect to the database. Structural uses the connection details to try to reach the database, and indicates whether it succeeded or failed. We strongly recommend that you test the connections.
The environment setting TONIC_TEST_CONNECTION_TIMEOUT_IN_SECONDS determines the number of seconds before a connection test times out. You can configure this setting from the Environment Settings tab on Structural Settings. By default, the connection test times out after 15 seconds.
A file connector workspace uses files as its source data and produces transformed versions of those files as its output.
For file connector workspaces, the File Location section indicates where the source files are obtained from - either a local file system or a cloud storage solution (Amazon S3 or Google Cloud Storage).
When the files come from cloud storage, the Output Location section indicates where to write the transformed files. You must also provide the cloud storage connection credentials.
For more information, go to Configuring the file connector storage type and output options.
Tonic Ephemeral is a separate Tonic.ai product that allows you to create temporary databases to use for testing and demos. For more information about Ephemeral, go to the .
