Python thread pool ThreadPool usage

Recently, I am working on a video device management project. The devices include (camera, DVR, NVR, etc.), including device information completion, device status push, device stream address push, etc. If a large number of devices are imported at the same time, if a single thread is used for device detection, the large number of devices will bring a large delay. Therefore, multithreading is considered to deal with this problem.

You can use Python language to implement thread pool, or you can use a third-party package ThreadPool thread pool package. This topic mainly introduces the use of ThreadPool and its specific implementation.

1. Installation

Use installation:

2. Use

(1) Introduce ThreadPool module (2) define thread function (3) create thread pool ThreadPool. Threadpool() (4) create tasks that need to be processed by thread pool, i.e. ThreadPool. Makerequests() (5) put multiple created tasks into thread pool, ThreadPool. Putrequest (6) etc. until all tasks are processed theadpool. Pool()

The above is a specific thread pool usage process. The specific definition of ThreadPool is as follows:

The next section will introduce the whole process and each function in detail: Python thread pool (Implementation)

The above is the whole content of this article. I hope it will be helpful to your study, and I hope you can support programming tips.
