> Apex platform assumes that an operator interacts with the platform using the dedicated operator thread. Currently, operators may create worker threads and emit tuples from a worker thread. This leads to undefined behavior and hard to find bugs, so it should be possible to enforce that DefaultOutputPort.emit() and/or Sink.put() are called on the operator thread.
