In Golang programming, the Worker Pool concurrency pattern is often used. A high-performance, feature-rich, and easy-to-use Worker Pool program should include which features?

DevChat

A high-performance, feature-rich, and easy-to-use Worker Pool program in Golang programming should include the following features:

1. Task Queue: The Worker Pool needs a task queue to store pending tasks. This queue should be thread-safe and support multiple workers fetching tasks from it simultaneously.

2. Dynamic Adjustment of Worker Numbers: The Worker Pool should be able to dynamically increase or decrease the number of workers based on the number of tasks and system load.

3. Graceful Shutdown: When there are no more tasks to process, or when a shutdown signal is received, the Worker Pool should be able to shut down gracefully, i.e., stop accepting new tasks and wait for all started tasks to complete before shutting down.

4. Error Handling: The Worker Pool should be able to handle errors that occur during task execution, for example, by providing an error callback function.

5. Task Timeout Handling: The Worker Pool should be able to handle task execution timeouts, for example, by setting a timeout period. If a task is not completed within this period, it is considered a failed task.

6. Task Priority: The Worker Pool can support task priority, prioritizing tasks with higher priority.

7. Task Result Retrieval: The Worker Pool should provide a way to retrieve task results, for example, by providing a result callback function.

8. Task Retry: For failed tasks, the Worker Pool can provide a retry mechanism, for example, by setting the number of retries and the retry interval.

9. Task Progress Tracking: The Worker Pool can provide task progress tracking, for example, by providing a progress callback function, or a method to query the current task progress.

10. Concurrency Control: The Worker Pool should be able to control the number of concurrent tasks to prevent system overload.

I want to develop a Worker Pool program, named GoPool, and open source it on GitHub. Now I need you to help me write an English README.md, which should include the features you summarized.

Here is a draft of the README.md file based on your requirements:

GoPool

GoPool is a high-performance, feature-rich, and easy-to-use worker pool library for Golang. It is designed to manage and recycle a pool of goroutines to complete tasks concurrently, improving the efficiency and performance of your applications.

Features

• Task Queue: GoPool uses a thread-safe task queue to store tasks waiting to be processed. Multiple workers can simultaneously fetch tasks from this queue.

• Dynamic Worker Adjustment: GoPool can dynamically adjust the number of workers based on the number of tasks and system load.

• Graceful Shutdown: GoPool can shut down gracefully. It stops accepting new tasks and waits for all ongoing tasks to complete before shutting down when there are no more tasks or a shutdown signal is received.

• Error Handling: GoPool can handle errors that occur during task execution. For example, it can provide an error callback function.

• Task Timeout Handling: GoPool can handle task execution timeouts. For example, it can set a timeout period, and if a task is not completed within this period, the task is considered failed.

• Task Priority: GoPool supports task priority. Tasks with higher priority are processed first.

• Task Result Retrieval: GoPool provides a way to retrieve task results. For example, it can provide a result callback function.

• Task Retry: GoPool provides a retry mechanism for failed tasks. For example, it can set the number of retries and the retry interval.

• Task Progress Tracking: GoPool provides task progress tracking. For example, it can provide a progress callback function or a method to query the current task progress.

• Concurrency Control: GoPool can control the number of concurrent tasks to prevent system overload.

Installation

To install GoPool, use go get:

go get -u github.com/yourusername/gopool

Usage

Here is a simple example of how to use GoPool:
