Streak JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with Streak.



Access and process Streak data in Apache NiFi using the CData JDBC Driver.

Apache NiFi supports powerful and scalable directed graphs of data routing, transformation, and system mediation logic. When paired with the CData JDBC Driver for Streak, NiFi can work with live Streak data. This article describes how to connect to and query Streak data from an Apache NiFi Flow.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live Streak data. When you issue complex SQL queries to Streak, the driver pushes supported SQL operations, like filters and aggregations, directly to Streak and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze Streak data using native data types.

Connecting to Streak Data in Apache NiFi

  1. Download the CData JDBC Driver for Streak installer, unzip the package, and run the JAR file to install the driver.
  2. Copy the CData JDBC Driver JAR file (and license file if it exists), cdata.jdbc.streak.jar (and cdata.jdbc.streak.lic), to the Apache NiFi lib subfolder, for example, C:\nifi-1.3.0-bin\nifi-1.3.0\lib.

    On Windows, the default location for the CData JDBC Driver is C:\Program Files\CData\CData JDBC Driver for Streak.

  3. Start Apache NiFi. For example:

    cd C:\nifi-1.3.0-bin\nifi-1.3.0\bin
    run-nifi.bat
    
  4. Navigate to the Apache NiFi UI in your web browser: typically http://localhost:8080/nifi
  5. Click the (Configuration) button from the Operate sidebar.
  6. In the NiFi Flow Configuration page, navigate to the Controller Services tab.
  7. Click the button to create a new controller service.
  8. In the Add Controller Service page, select DBCPConnection Pool, and then click Add.
  9. Click the gear button to configure the new DBCPConnection Pool.
  10. In the Configure Controller Service page, navigate to the Properties tab. Fill in the properties:

    PropertyValue
    Database Connection URLjdbc:streak:ApiKey=8c84j9b4j54762ce809ej6a782d776j3;
    Database Driver Class Namecdata.jdbc.streak.StreakDriver

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.streak.jar

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

    Use the following steps to generate a new API key for authenticating to Streak.

    1. Navigate to Gmail
    2. Click on the Streak dropdown to the right of the search bar
    3. Select the Integrations button. This will open a window where you can view existing integrations and create new API keys.
    4. Under the Streak API section of integrations, click the button to Create New Key.
  11. Click the button to enable the new DBCPConnection Pool.

Your Streak data is now available for use in Apache NiFi. For example, you can use the DBCPConnection Pool as the source for a QueryDatabaseTable processor.
