Oracle Data Integrator 12.2.1 brings a number of Big Data features such as Spark and Pig language generation support, executing ODI jobs in the Oozie workflow engine, and all new knowledge modules with improved Hive support.
We provided a first release of most Big Data features as a patch 18.104.22.168.1 on top of the 12.1.3 release, and have included it now as part of the 12.2.1 release. In addition, we provided further improvements to the initial feature set, such as new Oozie Execution modes. You can now choose between Task and Session execution modes for Oozie workflow generation. The new Session mode allows support for transactions, scripting, and loops in packages and will run a session in a single Oozie action, whereas the Task mode uses a separate Oozie action for each ODI task. ODI will automatically choose the correct mode based on the executed object or the mode can also be manually selected.
ODI provides developer productivity and can future-proof your investment by overcoming the need to manually code Hadoop transformations to a particular language. You can logically design your mapping and then choose the implementation that best suits your use case.
