"The Python API supports different runtime execution modes from which you "

"The purpose of the introduction of ``THREAD`` mode is to overcome the "
"overhead of serialization/deserialization and network communication "
"introduced of inter-process communication in the ``PROCESS`` mode. So if "
"performance is not your concern, or the computing logic of your Python "
"user-defined functions is the performance bottleneck of the job, "
"``PROCESS`` mode will be the best choice as ``PROCESS`` mode provides the"
" best isolation compared to ``THREAD`` mode."
