Integrate Amazon S3 Data in the Pentaho Report Designer

The CData JDBC driver for Amazon S3 data enables access to live data from dashboards and reports. This article shows how to connect to Amazon S3 data as a JDBC data source and publish reports based on Amazon S3 data in Pentaho.

Connect and Create a Report

1. Copy the JAR file of the driver, located in the lib subfolder of the installation directory, to the \Report-Designer\lib\jdbc\ folder in the Pentaho directory.
2. Run the report-designer.bat file in the \Report-Designer\ folder to open the Report-Designer UI.

3. Create a new data source with the driver by clicking Data -> Add Data Source -> Advanced -> JDBC (Custom) and then creating a new Amazon S3 connection. In the resulting dialog, configure the connection properties as shown below.

   • Custom Connection URL property: Enter the JDBC URL. This starts with jdbc:amazons3: and is followed by a semicolon-separated list of connection properties.

     To authorize Amazon S3 requests, provide the credentials for an administrator account or for an IAM user with custom permissions. Set AccessKey to the access key Id. Set SecretKey to the secret access key.

     Note: You can connect as the AWS account administrator, but it is recommended to use IAM user credentials to access AWS services.

     For information on obtaining the credentials and other authentication methods, refer to the Getting Started section of the Help documentation.

     Built-in Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the Amazon S3 JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

     java -jar cdata.jdbc.amazons3.jar
     

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

     When you configure the JDBC URL, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

     Below is a typical JDBC URL:

     jdbc:amazons3:AccessKey=a123;SecretKey=s123;

   • Custom Driver Class Name: Enter cdata.jdbc.amazons3.AmazonS3Driver.
   • User Name: The username to authenticate with.
   • Password: The password to authenticate with.

Add Amazon S3 Data to a Report

You are now ready to create a report with Amazon S3 data.

1. Add the Amazon S3 source to your report: Click Data -> Add Data Source -> JDBC and select the data source.

2. Configure the query. This article uses the one below:

   SELECT Name, OwnerId FROM ObjectsACL WHERE Name = 'TestBucket'

   👁 The query to retrieve data, specified in the JDBC data source configuration wizard. (Salesforce is shown.)
   
3. Drag a chart onto your report and double-click it to edit the chart. Run the report to display the chart. You can use the results of this query to create a simple chart for the ObjectsACL table.
4. Finally, run the report to see the chart.
