Use the CData JDBC Driver for AlloyDB in MicroStrategy Desktop

MicroStrategy is an analytics and mobility platform that enables data-driven innovation. When you pair MicroStrategy with the CData JDBC Driver for AlloyDB, you gain database-like access to live AlloyDB data from MicroStrategy, expanding your reporting and analytics capabilities. In this article, we walk through adding AlloyDB as a data source in MicroStrategy Desktop and creating a simple visualization of AlloyDB data.

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

Connect to and Visualize AlloyDB Data using MicroStrategy Desktop

In addition to connecting to AlloyDB in MicroStrategy enterprise products, you can connect to AlloyDB in MicroStrategy Desktop. Follow the steps below to add AlloyDB data as a dataset using JDBC and create visualizations and reports of AlloyDB data.

1. Open MicroStrategy Desktop and create a new dossier.
2. In the datasets panel, click New Data, select Databases, and choose Select a Table as the Import Option.
3. Add a new data source and choose the DSN-less data sources option.
4. Choose Generic in the Database menu and Generic DBMS in the Version menu.
5. Click the link to show the connection string and opt to edit the connection string. In the Driver menu, select MicroStrategy Cassandra ODBC Driver. (MicroStrategy requires a certified driver to interface through JDBC; the actual driver will not be used.)
6. Set the connection string as follows and click OK:
   • Add the JDBC keyword to the connection string.
   • Set MSTR_JDBC_JAR_FOLDER to the path of the JAR file for the JDBC driver. (C:\Program Files\CData JDBC Driver for AlloyDB\lib\ on Windows.)
   • Set DRIVER to cdata.jdbc.alloydb.AlloyDBDriver, the driver class.
   • Set URL to the JDBC URL for the AlloyDB driver, setting the necessary connection properties.

     The following connection properties are usually required in order to connect to AlloyDB.

     • Server: The host name or IP of the server hosting the AlloyDB database.
     • User: The user which will be used to authenticate with the AlloyDB server.
     • Password: The password which will be used to authenticate with the AlloyDB server.

     You can also optionally set the following:

     • Database: The database to connect to when connecting to the AlloyDB Server. If this is not set, the user's default database will be used.
     • Port: The port of the server hosting the AlloyDB database. This property is set to 5432 by default.

     Authenticating with Standard Authentication

     Standard authentication (using the user/password combination supplied earlier) is the default form of authentication.

     No further action is required to leverage Standard Authentication to connect.

     Authenticating with pg_hba.conf Auth Schemes

     There are additional methods of authentication available which must be enabled in the pg_hba.conf file on the AlloyDB server.

     Find instructions about authentication setup on the AlloyDB Server here.

     Authenticating with MD5 Authentication

     This authentication method must be enabled by setting the auth-method in the pg_hba.conf file to md5.

     Authenticating with SASL Authentication

     This authentication method must be enabled by setting the auth-method in the pg_hba.conf file to scram-sha-256.

     Authenticating with Kerberos

     The authentication with Kerberos is initiated by AlloyDB Server when the ∏ is trying to connect to it. You should set up Kerberos on the AlloyDB Server to activate this authentication method. Once you have Kerberos authentication set up on the AlloyDB Server, see the Kerberos section of the help documentation for details on how to authenticate with Kerberos.

     Built-in Connection String Designer

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

     java -jar cdata.jdbc.alloydb.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.

   A typical connection string follows:

   JDBC;MSTR_JDBC_JAR_FOLDER=PATH\TO\JAR\;DRIVER=cdata.jdbc.alloydb.AlloyDBDriver;URL={jdbc:alloydb:User=alloydb;Password=admin;Database=alloydb;Server=127.0.0.1;Port=5432};
7. Right-click on the new data source, and choose Edit catalog options.
8. Edit the SQL Statement to SELECT * FROM SYS_SCHEMAS to read the metadata from the JDBC Driver.
9. Select the new data source to view the available tables. You may need to manually click the search icon in the Available Tables section to see the tables.
10. Drag tables into the pane to import them. Note: Since we create a live connection, we can import whole tables and utilize the filtering and aggregation features native to the MicroStrategy products.
11. Click Finish and choose the option to connect Live. Live connections are possible and effective, thanks to the high-performance data processing native to CData JDBC Drivers.
12. Choose a visualization, choose fields to display, and apply any filters to create a new visualization of AlloyDB data. Data types are discovered automatically through dynamic metadata discovery. Where possible, the complex queries generated by the filters and aggregations will be pushed down to AlloyDB, while any unsupported operations (which can include SQL functions and JOIN operations) will be managed client-side by the CData SQL engine embedded in the driver.
13. Once you are finished configuring the dossier, click File -> Save.

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