This account is used by Snaps in the Snowflake Snap Pack.

You can create an account from SnapLogic Designer or Manager. In Designer, when working on pipelines, every Snap that needs an account prompts you to create a new account or use an existing account. The accounts can be created in or used from:

  • Your private project folder: This folder contains the pipelines that will use the account.
  • Your Project Space’s shared folder: This folder is accessible to all the users that belong to the Project Space.
  • The global shared folder: This folder is accessible to all the users within an organization in the SnapLogic instance.

Account Configuration

In Manager, you can navigate to the required folder and create an account in it (see Accounts). To create an account for Snowflake: 

  1. Click Create, then select Snowflake > Snowflake S3 Database Account or Snowflake > Snowflake S3 Dynamic Account or Snowflake Azure Database Account.
  2. Supply an account label.
  3. Supply the Account properties and Advanced properties for your Snowflake Database account. When using Snowflake S3 Dynamic Account, you can specify the Account properties as expressions referencing pipeline parameters.
  4. (Optional) Supply additional information on this account in the Notes field of the Info tab.
  5. Click Apply.
Warning

Avoid changing account credentials while pipelines using them are in progress. This may lead to unexpected results, including locking the account.


Note

If the Snap fails to connect to the database, it will retry three more times. 

You can Validate an account connection when creating a Snowflake S3 Database Account but not when creating a Snowflake S3 Dynamic Account because the account properties of a dynamic account are provided dynamically as pipeline parameters.

The difference between Snowflake S3 Database Account and Snowflake S3 Dynamic Account is that in the latter you can specify the Account properties as expressions referencing pipeline parameters. For information on setting up a Snowflake Dynamic Account, see Using Pipeline Parameters in Account Configuration, below.


Note

For details on account encryption, see Using Account Encryption, below.

Using Account Encryption

Standard Encryption

If you are using Standard Encryption, the High sensitivity settings under Enhanced Encryption are followed.

Enhanced Encryption

If you have the Enhanced Account Encryption feature, the following describes which fields are encrypted for each sensitivity level selected per each account.

Account

  • High: Password
  • Medium + High: Username, password
  • Low + Medium + High: Username, password

Using Pipeline Parameters in Account Configuration

You can use pipeline parameters when configuring dynamic Snowflake accounts. For information on pipeline parameters, see Pipeline Parameters in Pipeline Properties.

Example

Define the following two pipeline parameters in the pipeline with which you want to associate the new account:

  • User_name
  • Pass_word

You will use these values in the dynamic account.

Back in the Snowflake pipeline, create a Snowflake Dynamic Account 

  • Set the expression toggle on for both Username and Password
  • Set Username to _user_name and Password to _password
  • Click Apply and fill the Snap Settings for the desired function.
Note
You cannot Validate an account connection when creating a Snowflake Dynamic Account because the account properties of a dynamic account are provided dynamically as pipeline parameters.


Apply the changes. Your dynamic account is now configured; and your username and password details should change as you update them in your pipeline parameters.
