Use CData driver technologies to create a virtual data source for IBM Cloud Data Engine 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 IBM Cloud Data Engine, Denodo users can work with live IBM Cloud Data Engine data alongside other enterprise data sources. This article walks through creating a virtual data source for IBM Cloud Data Engine in the Denodo Virtual DataPort Administrator.
With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live IBM Cloud Data Engine data. When you issue complex SQL queries to IBM Cloud Data Engine, the driver pushes supported SQL operations, like filters and aggregations, directly to IBM Cloud Data Engine 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 IBM Cloud Data Engine data using native data types.
Create the IBM Cloud Data Engine Virtual Port
To connect to live IBM Cloud Data Engine 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.
- Download the CData JDBC Driver for IBM Cloud Data Engine installer, unzip the package, and run the JAR file to install the driver.
- Copy the JAR File (and license file if it exists) from the installation location (typically C:\Program Files\CData\CData JDBC Driver for IBM Cloud Data Engine\lib\) to the Denodo external library directory (C:\Denodo\Denodo Platform\lib-external\jdbc-drivers\cdata-ibmclouddataengine-19).
- Open the Denodo Virtual DataPort Administrator tool and navigate to the Server Explorer tab.
- Right-click "admin" and select New -> Data source -> JDBC.
- Configure the JDBC Connection:
- Name: your choice, e.g.: ibmclouddataengine
- Database adapter: Generic
- Driver class path: C:\Denodo\Denodo Platform\lib-external\jdbc-drivers\cdata-ibmclouddataengine-19
- Driver class: cdata.jdbc.ibmclouddataengine.IBMCloudDataEngineDriver
Database URI: Set this to a JDBC URL using the necessary connection properties. For example,
jdbc:ibmclouddataengine:Api Key=MyAPIKey;Instance CRN=myInstanceCRN;Region=myRegion;Schema=mySchema;OAuth Client Id=myOAuthClientId;OAuth Client Secret=myOAuthClientSecret;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 IBM Cloud Data Engine JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.ibmclouddataengine.jar
Fill in the connection properties and copy the connection string to the clipboard.
IBM Cloud Data Engine uses the OAuth and HMAC authentication standards. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.
- Click the "Test connection" button to confirm the configuration and click Save.
View IBM Cloud Data Engine Data in the VirtualPort Administrator Tool
After creating the data source, you can create a base view of IBM Cloud Data Engine data for use in the Denodo Platform.
- Click the "Create base view" button in the newly created VirtualPort (admin.IBMCloudDataEngine).
- Expand the object tree and select the objects (tables) you wish to import.
- Click the "Create selected" button to create views of the IBM Cloud Data Engine data.
Optional: Click "Create associations from foreign keys" to define relationships between the objects. - With the view(s) created, navigate to a table (cdata_ibmclouddataengine_jobs) in the Server Explorer and double-click the selected table.
- In the new tab, click "Execution panel" to open a query panel.
- Customize the query in the "Execute" tab or use the default:
SELECT * FROM cdata_ibmclouddataengine_jobs CONTEXT ('i18n'='us_est', 'cache_wait_for_load'='true')
- Click Execute to view the data.
With the base view created, you can now work with live IBM Cloud Data Engine data like you would any other data source in Denodo Platform, for example, querying IBM Cloud Data Engine in the Denodo Data Catalog.
