Back Up Cassandra data to SQL Server through SSIS

Easily back up data to SQL Server using the CData ADO.NET Provider for Cassandra. This example uses an SSIS workflow to populate a database with Cassandra data.

The CData ADO.NET Provider for Cassandra connects Cassandra data to applications that provide backup, reporting, full-text search, analytics, and more.

This example demonstrates how to use the provider for Cassandra inside of a SQL Server SSIS workflow to directly transfer Cassandra data into a Microsoft SQL Server database. The exact same procedure outlined below can be used with any CData ADO.NET Data Providers to connect SQL Server directly with remote data via SSIS.

  1. Open Visual Studio and create a new Integration Services project.
  2. Add a new Data Flow task from the toolbox onto the Control Flow screen.
  3. In the Data Flow screen, add an ADO.NET Source and an OLE DB Destination from the toolbox.

  4. Add a new connection and select .NET Providers\CData ADO.NET Provider for Cassandra 2015.
  5. In the connection manager, enter the connection details for Cassandra data. Below is a typical connection string:

    Database=MyCassandraDB;Port=7000;Server=127.0.0.1;

    Set the Server, Port, and Database connection properties to connect to Cassandra. Additionally, to use internal authentication set the User and Password connection properties.

  6. Open the DataReader editor and set the following information:

    • ADO.NET connection manager: In the Connection Managers menu, select the Data Connection you just created.
    • Data access mode: Select 'SQL command'.
    • SQL command text: In the DataReader Source editor, open the Component Properties tab and enter a SELECT command, such as the one below:

      SELECT City, SUM(TotalDue) FROM Customer GROUP BY City

  7. Close the DataReader editor and drag the arrow below the DataReader Source to connect it to the OLE DB Destination.
  8. Open the OLE DB Destination and enter the following information in the Destination Component Editor.

    • Connection manager: Add a new connection. Enter your server and database information here. In this example, SQLExpress is running on a separate machine.
    • Data access mode: Set your data access mode to "table or view" and select the table or view to populate in your database.
  9. Configure any properties you wish on the Mappings screen.

  10. Close the OLE DB Destination Editor and run the project. After the SSIS task has finished executing, your database will be populated with data obtained from Cassandra data.
