Connect to Coinbase Data in RapidMiner

This article shows how you can easily integrate the CData JDBC driver for Coinbase into your processes in RapidMiner. This article uses the CData JDBC Driver for Coinbase to transfer Coinbase data to a process in RapidMiner.

Connect to Coinbase in RapidMiner as a JDBC Data Source

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

1. Add a new database driver for Coinbase: Click Connections -> Manage Database Drivers.
2. In the resulting wizard, click the Add button and enter a name for the connection.
3. Enter the prefix for the JDBC URL: jdbc:api:
4. Enter the path to the cdata.jdbc.api.jar file, located in the lib subfolder of the installation directory.
5. Enter the driver class: cdata.jdbc.api.APIDriver
6. Create a new Coinbase connection: Click Connections -> Manage Database Connections.
7. Enter a name for your connection.
8. For Database System, select the Coinbase driver you configured previously.
9. Enter your connection string in the Host box.

   Start by setting the Profile connection property to the location of the Coinbase Profile on disk (e.g. C:\profiles\Coinbase.apip). Next, set the ProfileSettings connection property to the connection string for Coinbase (see below).

   Coinbase API Profile Settings

   Coinbase uses OAuth-based authentication.

   First you need to register an OAuth app with Coinbase. This is done from your account under 'Settings' > 'API Access' > 'New OAuth2 Application'.

   After setting the following connection properties, you are ready to connect:

   • AuthScheme: Set this to OAuth.
   • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage the process to obtain the OAuthAccessToken.
   • OAuthClientId: Set this to the ClientID that is specified in you app settings.
   • OAuthClientSecret: Set this to the ClientSecret that is specified in you app settings.
   • CallbackURL: Set this to the Redirect URI you specified in your app settings.

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.api.jar

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

   A typical connection string is below:

   Profile=C:\profiles\Coinbase.apip;Authscheme=OAuth;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;
10. Enter your username and password if necessary.

You can now use your Coinbase connection with the various RapidMiner operators in your process. To retrieve Coinbase data, drag the Retrieve operator from the Operators view. With the Retrieve operator selected, you can then define which table to retrieve in the Parameters view by clicking the folder icon next to the "repository entry." In the resulting Repository Browser, you can expand your connection node to select the desired example set.

Finally, wire the output to the Retrieve process to a result, and run the process to see the Coinbase data.
