Soenneker.ConcurrentProcessing.Executor 3.0.122

Soenneker.ConcurrentProcessing.Executor

This executor efficiently handles multiple tasks with controlled concurrency. It is ideal for managing parallel execution of tasks while ensuring that no more than a specified number of tasks run simultaneously.

Key Features

• Concurrent Execution: Limits the number of concurrent tasks to prevent overloading.
• Failure Handling with Retry Logic: Automatically retries failed tasks with exponential backoff.
• Async Semaphore: Uses a non-blocking semaphore to control concurrency and ensure thread safety.
• CancellationToken support for task cancellation.

⚠️ Note:

• This is not a background processor. It only manages concurrency for tasks that are provided during execution.

Installation

dotnet add package Soenneker.ConcurrentProcessing.Executor

Example: Executing Multiple Tasks with Concurrency Control

using System;
using System.Collections.Generic;
using System.Threading;
using System.Threading.Tasks;
using Soenneker.ConcurrentProcessing.Executor;

public class Program
{
    public static async Task Main(string[] args)
    {
        var executor = new ConcurrentProcessingExecutor(maxConcurrency: 3);

        var tasks = new List<Func<CancellationToken, ValueTask>>
        {
            async (ct) => { 
                Console.WriteLine("Task 1 started"); 
                await Task.Delay(500, ct); 
                Console.WriteLine("Task 1 completed"); 
            },

            async (ct) => { 
                Console.WriteLine("Task 2 started"); 
                await Task.Delay(300, ct); 
                Console.WriteLine("Task 2 completed"); 
            },

            async (ct) => { 
                Console.WriteLine("Task 3 started"); 
                await Task.Delay(700, ct); 
                Console.WriteLine("Task 3 completed");
            },

            async (ct) => { 
                Console.WriteLine("Task 4 started"); 
                await Task.Delay(400, ct); 
                Console.WriteLine("Task 4 completed"); 
            }
        };

        await executor.Execute(tasks);
    }
}

Console Output

Task 1 started
Task 2 started
Task 3 started
Task 1 completed
Task 4 started
Task 2 completed
Task 3 completed
Task 4 completed
