-* `rheem-api`: provides an easy-to-use Scala and Java API to assemble Rheem plans (recommended)

+java ... org.apache.incubator.wayang.profiler.ga.GeneticOptimizerApp [configuration URL [execution log]]

You can then copy them into your configuration.

+Apache Wayang in contrast to classical data processing systems that provide one dedicated execution engine, Apache Wayang rather is a *meta processing framework*: You can specify your data processing app via one of Wayang's API and then Wayang will pick an optimal configuration of classical processing frameworks, such as Java Streams or Apache Spark, to run your app on. Finally, Wayang will also perform the execution, thereby hiding the different specific platform APIs and coordinate int [...]
This approach aims at freeing data engineers and software developers from the burden of knowing the zoo of different data processing systems, their APIs, strengths and weakness; the intricacies of coordinating and integrating different processing platforms; and the inflexibility when tying to a fix set of processing platforms.
