This section describes how to integrate the
|D s platform|
- Snowflake provides a cloud-database datawarehouse designed for big data processing and analytics. For more information, see https://www.snowflake.com.
For more information on supported versions, see Connection Types.
NOTE: This integration is supported only for deployments of
- SSO connections are not supported.
- If you do not provide a stage database, then the
must create one for you in the default database. In this default database, you must include a schema named

PUBLIC. For more information, please see the Snowflake documentation.
When relational connections are enabled, this connection type is automatically available. For more information, see Enable Relational Connections.
To create a Snowflake connection, you must enable the following feature. The job manifest feature enables the creation of a manifest file to track the set of temporary files written to S3 before publication to Snowflake.
NOTE: This feature must be enabled when the base storage layer is set to S3. Please verify the following.
D s config
Locate the following parameter and set it to
- Save your changes and restart the platform.
In Snowflake terminology, a stage is a database object that points to an external location on S3. It must be an external stage containing access credentials.
If a stage is used, it is typically the default bucket used on S3 for storage.
NOTE: For read-only connections to Snowflake, you must specify a Database for Stage. The connecting user must have write access to this database.
Tip: You can specify a separate database to use for your stage.
If a stage is not specified, a temporary stage is created using the current user's AWS credentials.
NOTE: Without a defined stage, you must have write permissions to the database from which you import. This database is used to create the temporary stage.
For more information on stages, see https://docs.snowflake.net/manuals/sql-reference/sql/create-stage.html.

Create Snowflake Connection
For more information, see Create Snowflake Connections.
After you create your connection, load a small dataset based on a table in the connected Snowflake database.
NOTE: For Snowflake connections, you must have write access to the database from which you are importing.
See Import Data Page.
- Perform a few simple transformations to the data. Run the job. See Transformer Page.
- Verify the results.
