WebbThe Thread Pool pattern helps to save resources in a multithreaded application and to contain the parallelism in certain predefined limits. When we use a thread pool, we write our concurrent code in the form of parallel tasks and submit them for execution to an instance of a thread pool. WebbA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior.
WebbNeed to Wait for ThreadPool to Close. The multiprocessing.pool.ThreadPool in Python provides a pool of reusable threads for executing ad hoc tasks..
