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:
- Click Create, then select Snowflake > Snowflake S3 Database Account or Snowflake > Snowflake S3 Dynamic Account or Snowflake Azure Database Account.
- Supply an account label.
- 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.
- (Optional) Supply additional information on this account in the Notes field of the Info tab.
- Click Apply.
Avoid changing account credentials while pipelines using them are in progress. This may lead to unexpected results, including locking the account.
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.
For details on account encryption, see Using Account Encryption, below.
Account Types
Snowflake Azure Database Account
You can use the Snowflake Azure Account option to create both standard and dynamic accounts. If you want to enter a dynamic value for a specific field, click the '=' button adjacent to the concerned field, and you can use expressions in the field to specify dynamic values as required.
Account Settings
Label | Required. The name for the account. Default value: None. | |
|---|---|---|
Account properties | Required. The information required to create the account. | |
JDBC jars | Required. The list of JDBC jars to be loaded (Snowflake JDBC jar 3.0.0 or higher). The Snowflake account has been tested for version 3.6.17 JDBC jar. Example: snowflake-jdbc-3.6.17.jar Default value: None. | |
Hostname | Required. The hostname of the Snowflake server to which you want to connect the new account. Example: demo.snowflake.net Default value: None. | |
Port Number | Required. The port number associated with the Snowflake database server that you want to use for this account. Default value: 443 | |
Username | The username that you want to use to connect to the database server. Example: testuser Default value: None. | |
Password | The password associated with the username specified above. This will be used as the default password while retrieving connections. Default value: None. | |
Database name | Required. The name of the database to which you want to connect. Example: testdb Default value: None. | |
Warehouse name | Required. The name of the warehouse to which you want to connect. Example: testwh Default value: None. | |
| JBDC Driver Class | The fully-qualified name of the JDBC driver class to be used for connecting to the server. Example: net.snowflake.client.jdbc.SnowflakeDriver Default value: com.snowflake.client.jdbc.SnowflakeDriver | |
Azure storage account name | The name of the instance of the Azure storage account. Example: testazurestorage Default value: None. | |
Azure storage account key | The key needed to connect to the instance of the Azure storage account listed above. You can use either of the two keys available in the Access Key tab of the dashboard in the Azure portal to populate this value.
Default value: None. | |
Container | The name of the Azure storage blob container that you want to use for hosting files. Example: Container1 Default value: None. | |
Path | The location of the folder in the container listed above where you want to host files. Example: Folder1/SubFolder1 Default value: None. | |
| Shared Access Token Signature Method | The method of supplying the SAS token to the Snaps. You can choose between the following two options:
Default value: User Supplied | |
| User token | The shared access token that you want to use to access the Azure storage blob folder specified in the Path above. You can get a valid SAS token from the Azure portal. This property is applicable only when you choose User Supplied in the Shared Access Token Signature Method field above. Default value: None. | |
| Client side encryption | Allows the Snaps to encrypt the blob before being uploaded to Microsoft Azure. You can choose between the following two options:
Default value: None. | |
| Custom key | The custom key that you want to use to access the Azure storage blob. This property is applicable only when you select Custom_Key in the Client side encryption field above. The key should be a 128- or 256-bit Base64-encoded key. Default value: None. | |
| Advanced properties | ||
URL Properties | Use these fields to configure the URLs associated with this account. | |
URL property name | The name of the URL property. Default value: None. Example: queryTimeout | |
URL property value | The URL property value associated with the URL property name. Default value: None. Example: 0 | |
Batch size | Required. The number of statements that you want to execute at a time. Select queries are not batched. Using a large batch size could use up the JDBC placeholder limit of 2100. Default value: 50 | |
Fetch size | Required. The number of rows you want a query to fetch during each execution. Large values could cause the server to run out of memory. Default value: 100 | |
Min pool size | Required. The minimum number of idle connections that you want the pool to maintain at a time. Default value: 3 Minimum value: 0 Maximum value: No limit | |
Max pool size | Required. The maximum number of connections that you want the pool to maintain at a time. Snowflake Bulk Load/Bulk Upsert/S3 Upsert Snap requires a minimum of 2 connections per Snap in a pipeline. For example, if a pipeline has a Snowflake Bulk Load Snap and an S3 Upsert Snap, then the pool size must be greater than or equal to 4 for successful execution. Default value: 50 Minimum value: 0 Maximum value: No limit | |
Max life time | Required. The maximum lifetime of a connection in the pool. Ensure that the value you enter is a few seconds shorter than any database or infrastructure-imposed connection time limit. A value of 0 indicates an infinite lifetime, subject to the Idle Timeout value. An in-use connection is never retired. Connections are removed only after they are closed. Default value: 60 | |
Idle Timeout | Required. The maximum amount of time a connection is allowed to sit idle in the pool. A value of 0 indicates that idle connections are never removed from the pool. Default value: 5 | |
Checkout timeout | Required. The number of milliseconds you want the system to wait for a connection to become available when the pool is exhausted. A value of 0 instructs the system to wait forever. For any other value, the system throws an exception after the wait time has expired. Default value: 10000 | |
Snowflake S3 Database Account
Snowflake S3 Dynamic Account

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.
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.
