Access and process Amazon Marketplace 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 Amazon Marketplace, NiFi can work with live Amazon Marketplace data. This article describes how to connect to and query Amazon Marketplace data from an Apache NiFi Flow.
With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live Amazon Marketplace data. When you issue complex SQL queries to Amazon Marketplace, the driver pushes supported SQL operations, like filters and aggregations, directly to Amazon Marketplace 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 Amazon Marketplace data using native data types.
Connecting to Amazon Marketplace Data in Apache NiFi
- Download the CData JDBC Driver for Amazon Marketplace installer, unzip the package, run the .exe file to install the driver.
Copy the CData JDBC Driver JAR file (and license file if it exists), cdata.jdbc.amazonmarketplace.jar (and cdata.jdbc.amazonmarketplace.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 Amazon Marketplace.
Start Apache NiFi by running the run-nifi.bat file in bin subfolder, for example, C:\nifi-1.3.0-bin\nifi-1.3.0\bin.
(OR)
Use the command prompt to navigate to the particular directory and run the run-nifi.bat file for example:
cd C:\nifi-1.3.0-bin\nifi-1.3.0\bin .\run-nifi.bat
Navigate to the Apache NiFi UI in your web browser: It should be https://localhost:8443/nifi.
Note: If users are utilizing an older version of Apache NiFi, they should access it via http://localhost:8080/nifi. In earlier versions, HTTP was the protocol employed. However, in the most recent version, HTTPS is the standard. By default, HTTP operates on port 8080, while HTTPS uses port 8443.
When accessing Apache NiFi via a URL, it prompts you to enter a username and password for login.
To retrieve login credentials, users should consult the 'App.log' file located within the log directory of their NiFi installation. This file typically contains the necessary details for accessing the NiFi interface.
- Click the (Configuration) button from the Operate sidebar under the "NiFi Flow" process group.
- In the NiFi Flow Configuration page, navigate to the "Controller Services" tab.
- Click the button to create a new controller service.
- In the Add Controller Service page, select "DBCPConnectionPool", and then click Add.
- In the Configure Controller Service page, navigate to the "Properties" tab.
- Click the gear button to configure the new DBCPConnection Pool.
Fill in the properties:
Property Value Database Connection URL jdbc:amazonmarketplace:AWS Access Key Id=myAWSAccessKeyId;AWS Secret Key=myAWSSecretKey;MWS Auth Token=myMWSAuthToken;Seller Id=mySellerId;Marketplace=United States; Database Driver Class Name cdata.jdbc.amazonmarketplace.AmazonMarketplaceDriver Database Driver Location(s) Path to your Apache NiFi's lib folder where the JAR files are present. Built-in Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the Amazon Marketplace JDBC Driver. Either double-click the JAR file or execute the JAR file from the command-line.
java -jar cdata.jdbc.amazonmarketplace.jar
Fill in the connection properties and copy the connection string to the clipboard.
To connect to the Amazon Marketplace Webservice (MWS), AWSAccessKeyId, MWSAuthToken, AWSSecretKey and SellerId are required. You can optionally set the Marketplace property. For more information on obtaining values for these properties, refer to the Help documentation.
- To establish a connection and execute a select query, simply drag and drop the processor (indicated by the yellow highlight) into the workspace.
- Select the 'ExecuteSQL' processor and click the 'Add' button to make it visible in the workspace.
- Click on the added processor (ExecuteSQL)to open the connection page.
- Click on the Verify Properties button and verify to test the connection.
- Ensure that all the verification results are successful, and then click on APPLY.
- Activate the connection by clicking the small button at the right corner of the screen.
Your Amazon Marketplace data is now available for use in Apache NiFi. For example, you can use the DBCPConnection Pool as the source for a QueryDatabaseTable processor (shown below).
