dispatch_next(self)[source]¶ Dispatch more data for parallel processing
This method is meant to be called concurrently by the multiprocessing callback. We rely on the thread-safety of dispatch_one_batch to protect against concurrent consumption of the unprotected iterator.
-
dispatch_one_batch(self, iterator)[source]¶ Prefetch the tasks for the next batch and dispatch them.
The effective size of the batch is computed here. If there are no more jobs to dispatch, return False, else return True.
The iterator consumption and dispatching is protected by the same lock so calling this function should be thread safe.
