Java transformation

Extend
Data Integration
functionality with the Java transformation. The Java transformation provides a simple, native programming interface to define transformation functionality with the Java programming language.
You can use the Java transformation to quickly define simple or moderately complex transformation functionality without advanced knowledge of the Java programming language. The Java transformation can be an active or passive transformation.
The Secure Agent requires a Java Development Kit (JDK) to compile the Java code and generate byte code for the transformation. Azul OpenJDK is installed with the Secure Agent, so you do not need to install a separate JDK. Azul OpenJDK includes the Java Runtime Environment (JRE).
The Secure Agent uses the JRE to execute generated byte code at run time. When you run a mapping or
mapping
task that includes a Java transformation, the Secure Agent uses the JRE to execute the byte code, process input rows, and generate output rows.
To create a Java transformation, you write Java code snippets that define the transformation logic. Define transformation behavior for a Java transformation based on the following events:
  • The transformation receives an input row.
  • The transformation has processed all input rows.
  • The transformation receives a transaction notification.
You can invoke expressions in a Java transformation only in advanced mode.
You cannot use the Java transformation with a Graviton-enabled cluster. For more information about Graviton-enabled clusters, see the Administrator help.
When you create a Java transformation, ensure that you review the Java code to verify that it is free from potentially unsafe active content such as queries, remote scripts, or data connections before you run the code in a mapping task.
