What will happen to the array length at the end when performing a concurrent append from 1000 goroutines?

If the connection to the server is interrupted after executing a REST request, error handling and retry logic should be implemented. In C#, this can be done using a try-catch block and, for example, the Polly library for managing retry policies.

An example of simple error handling:

using System.Net.Http;
using System.Threading.Tasks;

async Task<string> GetDataAsync(string url)
{
    using var client = new HttpClient();
    try
    {
        var response = await client.GetAsync(url);
        response.EnsureSuccessStatusCode();
        return await response.Content.ReadAsStringAsync();
    }
    catch (HttpRequestException ex)
    {
        // Log the error, you can implement a retry here
        Console.WriteLine($"Request error: {ex.Message}");
        // You can retry the request or return a default value
        throw;
    }
}

If the connection is interrupted, it is recommended to:

• Log the error for diagnostics.
• Implement retries with exponential backoff.
• Inform the user about the issue if necessary.

This will increase the reliability of server interactions.
