Retry Plan

Model retry attempts before an operation succeeds.

RetryPlan.cs

using System;

class Program
{
    static void Main()
    {
        int failuresBeforeSuccess = ;
        int maxAttempts = 3;
        int attempt = 0;
        string status = "failed";

        while (attempt < maxAttempts)
        {
            attempt++;

            if (attempt > failuresBeforeSuccess)
            {
                status = "success";
                break;
            }

            Console.WriteLine($"retryAfter={attempt}");
        }

        Console.WriteLine($"attempts={attempt}");
        Console.WriteLine($"status={status}");
    }
}

using System;

class Program

    static void Main()
    {

        string status = "failed";

        while (attempt < maxAttempts)

            attempt++;

            if (attempt > failuresBeforeSuccess)
            {
                status = "success";
                break;
            }

            Console.WriteLine($"retryAfter={attempt}");
        }

        Console.WriteLine($"attempts={attempt}");
        Console.WriteLine($"status={status}");
    }
}

using System;

class Program
{
    static void Main()
    {
        int failuresBeforeSuccess = ;
        int maxAttempts = 3;
        int attempt = 0;
        string status = "failed";

        while (attempt < maxAttempts)
        {
            attempt++;

            if (attempt > failuresBeforeSuccess)
            {
                status = "success";
                break;
            }

            Console.WriteLine($"retryAfter={attempt}");
        }

        Console.WriteLine($"attempts={attempt}");
        Console.WriteLine($"status={status}");
    }
}

async Async calls to remote resources often retry failed attempts, but the retry policy can be modeled with ordinary control flow.
