CData Connect



Create a virtual database for Kafka in CData Connect Cloud and connect to it from MicroStrategy.

MicroStrategy is an analytics and mobility platform that enables data-driven innovation. When you pair MicroStrategy with CData Connect Cloud, you gain database-like access to live Kafka data from MicroStrategy, expanding your reporting and analytics capabilities. In this article, we walk through creating a virtual database for Kafka in Connect Cloud and connecting to Connect Cloud in MicroStrategy to create a simple visualization of Kafka data.

As a cloud-based integration platform, Connect Cloud is ideal for working with cloud-based BI and analytics tools. With no servers to configure or data proxies to set up, you can simply use the web-based UI to create a virtual database for Kafka and connect from MicroStrategy to start performing analytics based on live Kafka data.

Configuring Connect Cloud

To work with live Kafka data in MicroStrategy, we need to create a virtual database for Kafka in Connect Cloud.

Create a Virtual MySQL Database for Kafka in Connect Cloud

CData Connect Cloud uses a straightforward, point-and-click interface to connect to data sources and create virtual databases.

  1. Open Connect Cloud and click Databases
  2. Select "Kafka" from Available Data Sources
  3. Enter the necessary authentication properties to connect to Kafka

    Set BootstrapServers and the Topic properties to specify the address of your Apache Kafka server, as well as the topic you would like to interact with.

    Authorization Mechanisms

    • SASL Plain: The User and Password properties should be specified. AuthScheme should be set to 'Plain'.
    • SASL SSL: The User and Password properties should be specified. AuthScheme should be set to 'Scram'. UseSSL should be set to true.
    • SSL: The SSLCert and SSLCertPassword properties should be specified. UseSSL should be set to true.
    • Kerberos: The User and Password properties should be specified. AuthScheme should be set to 'Kerberos'.

    You may be required to trust the server certificate. In such cases, specify the TrustStorePath and the TrustStorePassword if necessary.

  4. Click Test Database
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions

Connect to and Visualize Kafka Data Using MicroStrategy

You can connect to Kafka in MicroStrategy by adding a data source based on the native MySQL functionality. Once you have created a data source, you can build dynamic visualizations of Kafka data in MicroStrategy.

  1. Open MicroStrategy and select your project.
  2. Click Add External Data, select Databases, and use Select Tables as the Import Option.
  3. In the Import from Tables wizard, click to add a new Data Source.
  4. Select MySQL in the Database menu and select MySQL 5.x in the Version menu.
  5. Set the connection properties as follows:
    • Server Name: the URL for your Connect Cloud instance (i.e.: myinstance.cdatacloud.net)
    • Port Number: the port for your Connect Cloud MySQL service (3306 by default)
    • Database Name: the name of your virtual Kafka database (i.e.: ApacheKafka1)
    • User: a Connect Cloud user with permissions to access your Kafka database
    • Password: the password for your Connect Cloud user
    • Data Source Name: a name for the new external data source, like "Connect Cloud Kafka"
  6. Expand the menu for the new data source and choose "Edit Catalog Options"
  7. Edit the "SQL statement retrieve columns ..." query to include TABLE_SCHEMA = '#?Schema_Name?#' in the WHERE clause, and click Apply and then OK (the complete query is below).

    SELECT DISTINCT 
      TABLE_SCHEMA NAME_SPACE, 
      TABLE_NAME TAB_NAME, 
      COLUMN_NAME COL_NAME, 
      (CASE 
        WHEN 
          (DATA_TYPE LIKE '%char' AND (CHARACTER_SET_NAME='utf8' OR CHARACTER_SET_NAME='ucs2')) 
        THEN 
          CONCAT('n',DATA_TYPE) 
        ELSE 
          DATA_TYPE 
      END) DATA_TYPE, 
      CHARACTER_MAXIMUM_LENGTH DATA_LEN, 
      NUMERIC_PRECISION DATA_PREC, 
      NUMERIC_SCALE DATA_SCALE 
    FROM 
      INFORMATION_SCHEMA.COLUMNS 
    WHERE 
      TABLE_NAME 
    IN 
      (#TABLE_LIST#) AND TABLE_SCHEMA='#?Schema_Name?#' 
    ORDER BY 
      1,2,3
    
  8. Select the new data source and select the Namespace that corresponds to your virtual Kafka database (like ApacheKafka1).
  9. 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 to customize our datasets.
  10. Click Finish, choose the option to connect live, save the query, and choose the option to create a new dossier. Live connections are possible and effective, thanks to high-performance data processing native to CData Connect Cloud.
  11. Choose a visualization, choose fields to display, and apply any filters to create a new visualization of Kafka 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 Kafka, while any unsupported operations (which can include SQL functions and JOIN operations) will be managed by the CData SQL engine embedded in Connect Cloud.
  12. Once you have finished configuring the dossier, click File -> Save.
