Advanced topics

The following information in the Administer Pentaho Data Integration and Analytics document helps to extend your knowledge of the Adaptive Execution Layer (AEL) beyond basic setup and use:

• Specify Additional Spark Properties

  You can define additional Spark properties within the application.properties file or as run modification parameters within a transformation.
• Configuring AEL with Spark in a Secure Cluster

  If your AEL daemon server and your cluster machines are in a secure environment like a data center, you may only want to configure a secure connection between the PDI client and the AEL daemon server.
• Spark tuning

  Spark tuning parameters are available for PDI steps where it is functionally applicable.
