Python2: multiprocessing.dummy.Pool vs multiprocessing.pool.ThreadPool












1














In python 2, is there any difference between multiprocessing.dummy.Pool and multiprocessing.pool.ThreadPool? The source code seems to imply they're the same.

          They're the same (both on Py2 and Py3); multiprocessing.dummy.Pool is just a thin wrapper that imports and calls multiprocessing.pool.ThreadPool. The actual code is just:



          def Pool(processes=None, initializer=None, initargs=()):
          from multiprocessing.pool import ThreadPool
          return ThreadPool(processes, initializer, initargs)


          In general, I'd prefer using multiprocessing.dummy.Pool only because the existence of multiprocessing.dummy is officially documented, where multiprocessing.pool is not (it's an internal implementation detail).
