Use the CData ODBC Driver for Redshift in MicroStrategy



Connect to Redshift data in MicroStrategy Developer using the CData ODBC Driver for Redshift.

MicroStrategy is an analytics and mobility platform that enables data-driven innovation. When you pair MicroStrategy with the CData ODBC Driver for Redshift, you gain database-like access to live Redshift data from MicroStrategy, expanding your reporting and analytics capabilities. In this article, we walk through creating a database instance for Redshift in MicroStrategy Developer and creating a Warehouse Catalog based on Redshift data.

The CData ODBC Driver offers unmatched performance for interacting with live Redshift data in MicroStrategy due to optimized data processing built into the driver. When you issue complex SQL queries from MicroStrategy to Redshift, the driver pushes supported SQL operations, like filters and aggregations, directly to Redshift and utilizes the embedded SQL engine to process unsupported operations (often SQL functions and JOIN operations) client-side. With built-in dynamic metadata querying, you can visualize and analyze Redshift data using native MicroStrategy data types.

Connect to Redshift as an ODBC Data Source

Information for connecting to Redshift follows, along with different instructions for configuring a DSN in Windows and Linux environments (the ODBC Driver for Redshift must be installed on the machine hosting the connected MicroStrategy Intelligence Server).

To connect to Redshift, set the following:

  • Server: Set this to the host name or IP address of the cluster hosting the Database you want to connect to.
  • Port: Set this to the port of the cluster.
  • Database: Set this to the name of the database. Or, leave this blank to use the default database of the authenticated user.
  • User: Set this to the username you want to use to authenticate to the Server.
  • Password: Set this to the password you want to use to authenticate to the Server.

You can obtain the Server and Port values in the AWS Management Console:

  1. Open the Amazon Redshift console (http://console.aws.amazon.com/redshift).
  2. On the Clusters page, click the name of the cluster.
  3. On the Configuration tab for the cluster, copy the cluster URL from the connection strings displayed.

When you configure the DSN, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

Windows

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Linux

If you are installing the CData ODBC Driver for Redshift in a Linux environment, the driver installation predefines a system DSN. You can modify the DSN by editing the system data sources file (/etc/odbc.ini) and defining the required connection properties.

/etc/odbc.ini

[CData Redshift Sys] Driver = CData ODBC Driver for Redshift Description = My Description User = admin Password = admin Database = dev Server = examplecluster.my.us-west-2.redshift.amazonaws.com Port = 5439

For specific information on using these configuration files, please refer to the help documentation (installed and found online).

Create a Redshift Database Instance in MicroStrategy Developer

You can connect to Redshift in MicroStrategy Developer by adding a database instance based on the CData ODBC Driver for Redshift.*

  1. Open MicroStrategy Developer and select a Project Source.
  2. Navigate to Administration -> Configuration Managers -> Database Instances and right-click to add a new instance.
  3. Name the instance, select Generic DBMS as the database connection type, and create a new database connection.
  4. In the database connection wizard, name the connection and create a new Database Login name, using filler values for the user and password.
  5. Select the DSN that you configured earlier as the ODBC data source (i.e., CData Redshift Sys).
  6. Select the newly created database connection.
  7. In the Project Source, right-click the project and open the Project configuration.
  8. Navigate to Database Instances and select the newly created database instance.
  9. Close MicroStrategy Developer and restart the connected MicroStrategy Intelligence Server to complete the database instance creation.

With the database instance configured, you will now be able to connect to Redshift data from the Warehouse Catalog and Data Import.

Connect to Redshift Data from the Warehouse Catalog

Once you have created a database instance based on the ODBC Driver for Redshift, you can connect to data from the Warehouse Catalog.

  1. Select your project and click Schema -> Warehouse Catalog.
  2. In the Read Settings for the Catalog, click Settings and set the queries to retrieve the schema:
    • To retrieve the list of tables, use the following query:
      SELECT 
        CatalogName NAME_SPACE,
        TableName TAB_NAME 
      FROM 
        SYS_TABLES
              
    • To retrieve the list of columns for selected tables, use the following query:
      SELECT DISTINCT 
        CatalogName NAME_SPACE, 
        TableName TAB_NAME, 
        ColumnName COL_NAME, 
        DataTypeName DATA_TYPE, 
        Length DATA_LEN, 
        NumericPrecision DATA_PREC, 
        NumericScale DATA_SCALE 
      FROM 
        SYS_TABLECOLUMNS 
      WHERE 
        TableName IN (#TABLE_LIST#) 
      ORDER BY
        1,2,3
              
  3. Select tables to be used in the project.

Note: connecting using a ODBC driver requires a 3- or 4-tier architecture.
