Connect to Twitter Data and Transfer Data in Talend

Integrate Twitter data with standard components and data source configuration wizards in Talend Open Studio.

This article shows how you can easily integrate the CData JDBC driver for Twitter into your workflow in Talend. This article uses the CData JDBC Driver for Twitter to transfer Twitter data in a job flow in Talend.

Connect to Twitter in Talend as a JDBC Data Source

You can follow the procedure below to establish a JDBC connection to Twitter:

  1. Add a new database connection to Twitter data: To add a new connection, expand the Metadata node, right-click the Db Connections node, and then click Create Connection.
  2. In the resulting wizard, enter a name for the connection.
  3. On the next page, select Generic JDBC from the DB Type menu and enter the JDBC URL.

    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.

    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.

    A typical JDBC URL is below:

    jdbc:twitter:InitiateOAuth=GETANDREFRESH
  4. Enter the path to the cdata.jdbc.twitter.jar file, located in the lib subfolder of the installation directory.
  5. Right-click the connection and then click Retrieve Schema.
  6. Click Next with the default options to select the tables you want to import.
  7. Finish the wizard with the default options.

Output the Tweets Table to a Flat File

You can follow the procedure below to transfer the Tweets table to a flat file output component:

  1. In the Table Schemas node, drag the tables to the workspace.
  2. In the dialog that is displayed, select the tJDBCInput component.
  3. Next, drag a tFileOutputDelimited component from the Business Intelligence tab of the Palette into the workspace.
  4. Right-click the Tweets tJDBCInput component and drag a vector to the output file.

Run the project to transfer the data.
