org.apache.flink.compiler.PactCompiler
Utility class that traverses a plan to collect all nodes and add them to the OptimizedPlan. Besides collecting all nodes, this traversal assigns the memory to the nodes.

   *            The program's plan.
   * @return JSON dump of the optimized plan.
   * @throws Exception
