Create Amazon Athena Reports on JasperReports Server

The CData JDBC driver for Amazon Athena enables you to provide access to Amazon Athena data across the enterprise. This article shows how to deploy the driver on JasperReports server and create a simple report based on a reporting domain, a business view of Amazon Athena data.

Getting Started

---

Deploy the Driver JAR

Follow the steps below to deploy the driver JAR on JasperReports Server. The instructions below contain specifics for Amazon Athena and the Tomcat server bundled with JasperReports Server. If you are using JBoss AS 7 instead of Tomcat, you can follow the standard process to deploy the Amazon Athena JDBC Driver on JBoss.

1. Copy the driver JAR and .lic file, located in the lib subfolder of the installation directory, to the lib subfolder of the apache-tomcat folder, located in the JasperReports Server installation directory.

2. Navigate to apache-tomcat -> webapps -> jasperserver-pro -> META-INF and add the following resource entry to the context.xml file:

   <Resource name="jdbc/amazonathena" auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.amazonathena.AmazonAthenaDriver" url="jdbc:amazonathena:AWSAccessKey='a123';AWSSecretKey='s123';AWSRegion='IRELAND';Database='sampledb';S3StagingDirectory='s3://bucket/staging/';" maxActive="20" maxIdle="10" maxWait="-1" factory="com.jaspersoft.jasperserver.tomcat.jndi.JSCommonsBasicDataSourceFactory"/>
   

   Specify the required connection properties in the JDBC URL -- the url attribute.

   Authenticating to Amazon Athena

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

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

   Obtaining the Access Key

   To obtain the credentials for an IAM user, follow the steps below:

   1. Sign into the IAM console.
   2. In the navigation pane, select Users.
   3. To create or manage the access keys for a user, select the user and then select the Security Credentials tab.

   To obtain the credentials for your AWS root account, follow the steps below:

   1. Sign into the AWS Management console with the credentials for your root account.
   2. Select your account name or number and select My Security Credentials in the menu that is displayed.
   3. Click Continue to Security Credentials and expand the Access Keys section to manage or create root account access keys.

   Authenticating from an EC2 Instance

   If you are using the CData Data Provider for Amazon Athena 2018 from an EC2 Instance and have an IAM Role assigned to the instance, you can use the IAM Role to authenticate. To do so, set to true and leave and empty. The CData Data Provider for Amazon Athena 2018 will automatically obtain your IAM Role credentials and authenticate with them.

   Authenticating as an AWS Role

   In many situations it may be preferable to use an IAM role for authentication instead of the direct security credentials of an AWS root user. An AWS role may be used instead by specifying the . This will cause the CData Data Provider for Amazon Athena 2018 to attempt to retrieve credentials for the specified role. If you are connecting to AWS (instead of already being connected such as on an EC2 instance), you must additionally specify the and of an IAM user to assume the role for. Roles may not be used when specifying the and of an AWS root user.

   Authenticating with MFA

   For users and roles that require Multi-factor Authentication, specify the and connection properties. This will cause the CData Data Provider for Amazon Athena 2018 to submit the MFA credentials in a request to retrieve temporary authentication credentials. Note that the duration of the temporary credentials may be controlled via the (default 3600 seconds).

   Connecting to Amazon Athena

   In addition to the and properties, specify , and . Set to the region where your Amazon Athena data is hosted. Set to a folder in S3 where you would like to store the results of queries.

   If is not set in the connection, the data provider connects to the default database set in Amazon Athena.

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.amazonathena.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.

3. Navigate to jasperserver-pro -> WEB-INF and add the following reference to the web.xml file:

    Amazon Athena data JSP
    jdbc/amazonathena
    javax.sql.DataSource
    Container
   
   

4. Restart the server.

Create the Amazon Athena JDBC Data Source

Follow the steps below to map the Amazon Athena JDBC driver to a JDBC data source:

1. Log into JasperReports Server and click Create -> Data Source.
2. In the Type menu, select JNDI Data Source.
3. In the Service Name box, enter the JDNI lookup defined in the resource definition in the web.xml file. In the example, the lookup is "jdbc/amazonathena".
4. Click Save to create the Data Source.

Create a Domain

A domain is a metadata and access-control layer that surfaces a relevant business view to report creators. Follow the steps below to select Amazon Athena columns, apply filters, and execute SQL to create a domain.

1. Click Create -> Domain. Enter an Id for the domain and select a save location.
2. Click Browse in the Data Source section and select the Amazon Athena data source you created.
3. In the Domain Design section, click Create with Domain Designer.
4. Select the schema containing your tables.
5. On the Tables tab, select a table in the Data Source pane and then click the arrow to add them to the Selected Tables pane. 👁 Tables to add on the Tables tab in the Domain Designer. (Salesforce is shown.)
   
6. On the Derived Tables tab, you can define domains based on SQL queries. For example,

    SELECT Name, TotalDue FROM Customers
    

7. On the Joins tab, you can join tables by selecting the columns you want to build the join condition and selecting the join type.
8. On the Pre-Filters tab, drag and drop columns to define search criteria that filters the data exposed through the domain.
9. On the Display tab, select Amazon Athena data into the data sets presented to the user. 👁 Resources to add on the Display tab in the Domain Designer. (Salesforce is shown.)
   
10. Click OK to accept your changes and click Submit to create the domain.

Explore Data in Real Time

After you have created a domain, you are ready to connect to data. Follow the steps below to create an Ad Hoc View in the Ad Hoc Editor.

1. Click Create -> Ad Hoc View.
2. In the resulting dialog, select the Amazon Athena domain you created. 👁 The domain to be used for the view. (Salesforce is shown.)
   
3. On the Choose Data page, select columns that you want to use in the view. In the Pre-Filters section, you can create filters based on the selected fields. In the Display section, you can modify column information as presented by the domain. 👁 The columns to be used in the report. (Salesforce is shown.)
   
4. After completing the wizard, select the view type and add columns to the view. JasperSoft uses the metadata of the driver to detect the available dimensions and measures, based on the data type. Drag dimensions and measures onto the Columns and Rows boxes. Right-click a measure to change the summary calculation. Drag the Columns slider to the the desired data level in the Filters section.
5. To access updates to the data as you design the view, change the menu selection from Sample Data to Full Data in the design mode toolbar. As you make changes, JasperSoft Server executes the underlying SQL queries to the driver.
6. Save the view.

Create a Real-Time Report

You can now create reports hosted on JasperSoft Server. To do so from the Ad Hoc Editor, click Save Ad Hoc View and click Create Report.
