This section describes how to create a connection to your Snowflake datawarehouse. 

Pre-requisites


Limitations

Create Connection

You can create Snowflake connections through the following methods.

Create through application

Any user can create a Snowflake connection through the application.

Steps:

  1. Login to the application.
  2. In the menu, click Settings menu > Settings > Connections.
  3. In the Create Connection page, click the Snowflake connection card.
  4. Specify the properties for your Snowflake database connection. The following parameters are specific to Snowflake connections:

    NOTE: In Snowflake connections, property values are case-sensitive. Snowflake-related locations are typically specified in capital letters.

PropertyDescription
Account Name

Snowflake account to use. Suppose your hostname is the following:

mycompany.snowflakecomputing.com

Your account name is the following:

mycompany
WarehouseThe name of the warehouse to which to connect
Stage

If you have deployed a Snowflake stage for managing file conversion to tables, you can enter its name here. 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, then this value is typically the schema and the name of the stage. Example value:

MY_SCHEMA.MY_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.

Database for Stage

(optional) If you are using a Snowflake stage, you can specify a database other than the default one to host the stage.

NOTE: If you are creating a read-only connection to Snowflake, this field is required. The accessing user must have write permission to the specified database.

If no value is specified, then your stage must be in the default database.

For more information, see Create Connection Window.

Disable SSL connections

By default, connections to Snowflake use SSL. To disable, please add the following string to your Connect String Options:

;ssl=false

Save your changes.

Connect through proxy

If you require connection to Snowflake through a proxy server, additional Connect String Options are required. For more information, see https://docs.snowflake.net/manuals/user-guide/jdbc-configure.html#specifying-a-proxy-server-in-the-jdbc-connection-string.

Create via API

For more information, see API Connections Create v4.

Testing

Import a dataset from Snowflake. Add it to a flow, and specify a publishing action back to Snowflake. Run a job.For more information, see Verify Operations.
