Use the CData JDBC Driver for Presto in MicroStrategy

Connect to Presto data in MicroStrategy Developer using the CData JDBC Driver for Presto.

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

The CData JDBC Driver offers unmatched performance for interacting with live Presto data in MicroStrategy due to optimized data processing built into the driver. When you issue complex SQL queries from MicroStrategy to Presto, the driver pushes supported SQL operations, like filters and aggregations, directly to Presto 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 Presto data using native MicroStrategy data types.

Connect to Presto in MicroStrategy Developer

You can connect to Presto in MicroStrategy Developer by adding a database instance based on the CData JDBC Driver for Presto.* Before you begin, you will need to install the JDBC Driver for Presto on the machine hosting the MicroStrategy Intelligence Server that your instance of MicroStrategy Developer is connected to.

  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, setting the user and password for Presto.
  5. On the Advanced tab for the connection wizard, set the additional connection string parameters as follows.
    • Add the JDBC keyword to the connection string.
    • Set MSTR_JDBC_JAR_FOLDER to the path of the directory containing the JAR file for the JDBC driver. (C:\Program Files\CData JDBC Driver for Presto\lib\ on Windows.)
    • Set DRIVER to cdata.jdbc.presto.PrestoDriver, the driver class.
    • Set URL to the JDBC URL for the Presto driver, which contains the necessary connection properties.

      Set the Server and Port connection properties to connect, in addition to any authentication properties that may be required.

      To enable TLS/SSL, set UseSSL to true.

      Authenticating with LDAP

      In order to authenticate with LDAP, set the following connection properties:

      • AuthScheme: Set this to LDAP.
      • User: The username being authenticated with in LDAP.
      • Password: The password associated with the User you are authenticating against LDAP with.

      Authenticating with Kerberos

      In order to authenticate with KERBEROS, set the following connection properties:

      • AuthScheme: Set this to KERBEROS.
      • KerberosKDC: The Kerberos Key Distribution Center (KDC) service used to authenticate the user.
      • KerberosRealm: The Kerberos Realm used to authenticate the user with.
      • KerberosSPN: The Service Principal Name for the Kerberos Domain Controller.
      • KerberosKeytabFile: The Keytab file containing your pairs of Kerberos principals and encrypted keys.
      • User: The user who is authenticating to Kerberos.
      • Password: The password used to authenticate to Kerberos.

      Built-in Connection String Designer

      For assistance in constructing the JDBC URL, use the connection string designer built into the Presto JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

      java -jar cdata.jdbc.presto.jar

      Fill in the connection properties and copy the connection string to the clipboard.

      When you configure the JDBC URL, 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.

    Typical additional connection string properties follow:

    JDBC;MSTR_JDBC_JAR_FOLDER=PATH\TO\JAR\;DRIVER=cdata.jdbc.presto.PrestoDriver;URL={jdbc:presto:Server=127.0.0.1;Port=8080;};
  6. Ensure that you have not selected an ODBC data source (this will trigger MicroStrategy to use the additional connection string parameters to build the database instance) and click OK.
  7. Click OK to close the database instance wizard.
  8. In the Project Source, right-click the project and open the Project configuration.
  9. Navigate to Database Instances, select the newly created database instance, and click OK.
  10. 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 Presto data from the Warehouse Catalog and Data Import.

Connect to Presto Data from the Warehouse Catalog

Once you have created a database instance based on the JDBC Driver for Presto, 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 * 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.

Using the CData JDBC Driver for Presto in MicroStrategy, you can easily create robust visualizations and reports on Presto data. Read our other articles on connecting to Presto in MictroStrategy Web and connecting to Presto in MicroStrategy Desktop for more information.


Note: Connecting using a JDBC Driver requires a 3- or 4-Tier Architecture.
