  /***
   * <p>Used to specify if a given API invocation in the in-memory interpreter is going to be invoked for all the worker
   *  threads, a sticky thread or just any one thread.
   *
   *  - {@link WorkerExecutionMode#BROADCAST} is to be used when the
   *   command is resulting in a state of the interpreter which has to be used in subsequent calls. For example,
   *   deserializing a machine learning model can be used as a BROADCAST model as the scoring can then be invoked across
   *   all worker threads if required.
   *  - {@link WorkerExecutionMode#ANY} Represents a state wherein any worker can be used to execute the code.
   *   Example would be scoring an incoming tuple on which the model has already been deserialized across all nodes
   *  - {@link WorkerExecutionMode#STICKY} Use STICKY if the same worker needs to service the request.
   *    The downside of this is that it may or may not complete on time and depends on the queue length.</p>
   *
   *   <p><b>Ensure the {@link PythonInterpreterRequest#hashCode()} is overridden if STICKY is chosen </b></p>
