Migrating data from Zuora to Snowflake using CData SSIS Components.

Snowflake is a leading cloud data warehouse and a popular backbone for enterprise BI, analytics, data management, and governance initiatives. Snowflake offers features such as data sharing, real-time data processing, and secure data storage which makes it a common choice for cloud data consolidation.

The CData SSIS Components enhance SQL Server Integration Services by enabling users to easily import and export data from various sources and destinations.

In this article, we explore the data type mapping considerations when exporting to Snowflake and walk through how to migrate Zuora data to Snowflake using the CData SSIS Components for Zuora and Snowflake.

Data Type Mapping

Special Considerations

• Casing: Snowflake enforces an exact case match by default for identifiers, so it is common to run into issues that can be attributed to mismatched casing. Set the IgnoreCase property to True in your CData SSIS Components for Snowflake connection to resolve these issues. This property directly maps to the QUOTED_IDENTIFIERS_IGNORE_CASE property in Snowflake and specifies whether Snowflake will treat identifiers as case-sensitive.

• Timestamps: Snowflake supports three timestamp types:

  • TIMESTAMP_NTZ: This timestamp stores UTC time with a specified precision. However, all operations are performed in the current session's time zone, controlled by the TIMEZONE session parameter.
  • TIMESTAMP_LTZ: This timestamp stores "wallclock" time with a specified precision. All operations are performed without taking any time zone into account.
  • TIMESTAMP_TZ: This timestamp stores UTC time together with an associated time zone offset. When a time zone isn't provided, the session time zone offset is used.

  By default the CData SSIS Components write timestamps to Snowflake as TIMESTAMP_NTZ unless manually configured.

Prerequisites

• Visual Studio 2022
• SQL Server Integration Services Projects extension for Visual Studio 2022
• CData SSIS Components for Snowflake
• CData SSIS Components for Zuora

Create the project and add components

1. Open Visual Studio and create a new Integration Services Project.
2. Add a new Data Flow Task to the Control Flow screen and open the Data Flow Task.
3. Add a CData Zuora Source control and a CData Snowflake Destination control to the data flow task.

Configure the Zuora source

Follow the steps below to specify properties required to connect to Zuora.

1. Double-click the CData Zuora Source to open the source component editor and add a new connection.
2. In the CData Zuora Connection Manager, configure the connection properties, then test and save the connection.

   Zuora uses the OAuth standard to authenticate users. See the online Help documentation for a full OAuth authentication guide.

   Configuring Tenant property

   In order to create a valid connection with the provider you need to choose one of the Tenant values (USProduction by default) which matches your account configuration. The following is a list with the available options:

   • USProduction: Requests sent to https://rest.zuora.com.
   • USAPISandbox: Requests sent to https://rest.apisandbox.zuora.com"
   • USPerformanceTest: Requests sent to https://rest.pt1.zuora.com"
   • EUProduction: Requests sent to https://rest.eu.zuora.com"
   • EUSandbox: Requests sent to https://rest.sandbox.eu.zuora.com"

   Selecting a Zuora Service

   Two Zuora services are available: Data Query and AQuA API. By default ZuoraService is set to AQuADataExport.

   DataQuery

   The Data Query feature enables you to export data from your Zuora tenant by performing asynchronous, read-only SQL queries. We recommend to use this service for quick lightweight SQL queries.

   Limitations
   • The maximum number of input records per table after filters have been applied: 1,000,000
   • The maximum number of output records: 100,000
   • The maximum number of simultaneous queries submitted for execution per tenant: 5
   • The maximum number of queued queries submitted for execution after reaching the limitation of simultaneous queries per tenant: 10
   • The maximum processing time for each query in hours: 1
   • The maximum size of memory allocated to each query in GB: 2
   • The maximum number of indices when using Index Join, in other words, the maximum number of records being returned by the left table based on the unique value used in the WHERE clause when using Index Join: 20,000

   AQuADataExport

   AQuA API export is designed to export all the records for all the objects ( tables ). AQuA query jobs have the following limitations:

   Limitations
   • If a query in an AQuA job is executed longer than 8 hours, this job will be killed automatically.
   • The killed AQuA job can be retried three times before returned as failed.
   
3. After saving the connection, select "Table or view" and select the table or view to export into Snowflake, then close the CData Zuora Source Editor.

Configure the Snowflake destination

With the Zuora Source configured, we can configure the Snowflake connection and map the columns.

1. Double-click the CData Snowflake Destination to open the destination component editor and add a new connection.
2. In the CData Snowflake Connection Manager, configure the connection properties, then test and save the connection.
   • The component supports Snowflake user authentication, federated authentication, and SSL client authentication. To authenticate, set User and Password, and select the authentication method in the AuthScheme property. Starting with accounts created using Snowflake’s bundle 2024_08 (October 2024), password-based authentication is no longer supported due to security concerns. Instead, use alternative authentication methods such as OAuth or Private Key authentication.

   Other helpful connection properties

   • QueryPassthrough: When this is set to True, queries are passed through directly to Snowflake.
   • ConvertDateTimetoGMT: When this is set to True, the components will convert date-time values to GMT, instead of the local time of the machine.
   • IgnoreCase: A session parameter that specifies whether Snowflake will treat identifiers as case sensitive. Default: false(case is sensitive).
   • BindingType: There are two kinds of binding types: DEFAULT and TEXT. DEFAULT uses the binding type DATE for the Date type, TIME for the Time type, and TIMESTAMP_* for the Timestamp_* type. TEST uses the binding type TEXT for Date, Time, and Timestamp_* types.
   
3. After saving the connection, select a table in the Use a Table menu and in the Action menu, select Insert.
4. On the Column Mappings tab, configure the mappings from the input columns to the destination columns.

Run the project

You can now run the project. After the SSIS Task has finished executing, data from your SQL table will be exported to the chosen table.
