Twitter JDBC Driver

A straightforward interface to connect any Java application with Twitter integration capabilities including Search, GeoSearch, UserInfo, DirectMessages, Followers, and more!



Use the CData JDBC Driver for Twitter to create a virtual data source for Twitter data in the Denodo Virtual DataPort Administrator.

Denodo Platform is a data virtualization product providing a single point of contact for enterprise database data. When paired with the CData JDBC Driver for Twitter, Denodo users can work with live Twitter data alongside other enterprise data sources. This article walks through creating a virtual data source for Twitter in the Denodo Virtual DataPort Administrator.

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

Create a Twitter Virtual Port

To connect to live Twitter data from Denodo, you need to copy the JDBC Driver JAR file to the external library directory for Denodo and create a new JDBC Data Source from the Virtual DataPort Administrator tool.

  1. Download the CData JDBC Driver for Twitter installer, unzip the package, and run the JAR file to install the driver.
  2. Copy the JAR File (and license file if it exists) from the installation location (typically C:\Program Files\CData\CData JDBC Driver for Twitter\lib\) to the Denodo external library directory (C:\Denodo\Denodo Platform\lib-external\jdbc-drivers\cdata-twitter-19).
  3. Open the Denodo Virtual DataPort Administrator tool and navigate to the Server Explorer tab.
  4. Right-click "admin" and select New -> Data source -> JDBC.
  5. Configure the JDBC Connection:
    • Name: your choice, e.g.: twitter
    • Database adapter: Generic
    • Driver class path: C:\Denodo\Denodo Platform\lib-external\jdbc-drivers\cdata-twitter-19
    • Driver class: cdata.jdbc.twitter.TwitterDriver
    • Database URI: Set this to a JDBC URL using the necessary connection properties. For example,

      jdbc:twitter:InitiateOAuth=GETANDREFRESH

      Information on creating the Database URI follows:

      Built-In Connection String Designer

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

      java -jar cdata.jdbc.twitter.jar

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

      All tables require authentication. You can connect using your User and Password or OAuth. To authenticate using OAuth, you can use the embedded OAuthClientId, OAuthClientSecret, and CallbackURL or you can register an app to obtain your own.

      If you intend to communicate with Twitter only as the currently authenticated user, then you can obtain the OAuthAccessToken and OAuthAccessTokenSecret directly by registering an app.

      See the Getting Started chapter in the help documentation for a guide to using OAuth.

  6. Click the "Test connection" button to confirm the configuration and click Save.

View Twitter Data in the VirtualPort Administrator Tool

After creating the data source, you can create a base view of Twitter data for use in the Denodo Platform.

  1. Click the "Create base view" button in the newly created VirtualPort (admin.Twitter).
  2. Expand the object tree and select the objects (tables) you wish to import.
  3. Click the "Create selected" button to create views of the Twitter data.
    Optional: Click "Create associations from foreign keys" to define relationships between the objects.
  4. With the view(s) created, navigate to a table (cdata_twitter_tweets) in the Server Explorer and double-click the selected table.
  5. In the new tab, click "Execution panel" to open a query panel.
  6. Customize the query in the "Execute" tab or use the default:
    SELECT * FROM cdata_twitter_tweets CONTEXT ('i18n'='us_est', 'cache_wait_for_load'='true')
    
  7. Click Execute to view the data.

With the base view created, you can now work with live Twitter data like you would any other data source in Denodo Platform, for example, querying Twitter in the Denodo Data Catalog.
