The concurrent.futures module provides a high-level interface for asynchronously executing callables.. The asynchronous execution can be performed with threads, using ThreadPoolExecutor, or separate processes, using ProcessPoolExecutor.Both implement the same interface, which is defined by the abstract Executor class. The concurrent.futures module is part of the standard library which provides a high level API for launching async tasks. We will discuss and go through code samples for the common usages of this module. Executors This module features the Executor class which is an abstract class and it can concurrent.futures is a module of the standard library that provides a high-level API for running asynchronous code using threads or processes. This tutorial makes a case for when it can come in handy for things such as data processing or web applications, while briefly exploring better alternatives for specific use cases.

The following are code examples for showing how to use concurrent.futures.ProcessPoolExecutor().They are from open source Python projects. You can vote up the examples you like or vote down the ones you don't like. Creating an instance of Callable does not take us anywhere, we still have to pass this instance to an executor that will take care of starting that task in a new thread and give us back the valuable Future object. That's where ExecutorService comes in.. There are a few ways we can get ahold of an ExecutorService instance, most of them are provided by utility class Executors‘ static factory In the asyncio model, execution is scheduled and coordinated by an event loop. To cancel execution of a currently suspended task, you essentially simply have to not resume it. While this works a little different in practice, it should be obvious that this makes cancelling a suspended task simple in theory.
