Adaptive rate limiting using ephemeral signals for automatic backoff.

dotnet add package mostlylucid.ephemeral.patterns.adaptiverate

Quick Start

using Mostlylucid.Ephemeral.Patterns.AdaptiveRate;

await using var service = new AdaptiveRateService<ApiRequest>(
    async (req, ct) => await CallApiAsync(req, ct),
    maxConcurrency: 8);

// Automatically backs off when rate-limit signals present
await service.ProcessAsync(request);

All Options

new AdaptiveRateService<T>(
    // Required: async work processor
    processAsync: async (item, ct) => await ProcessAsync(item, ct),

    // Max concurrent operations
    // Default: 8
    maxConcurrency: 8
)

API Reference

// Process item with automatic rate limit handling
await service.ProcessAsync(item);

// Check queue status
int pending = service.PendingCount;
int active = service.ActiveCount;

// Dispose
await service.DisposeAsync();

Signal Format

  • rate-limit - Generic rate limit, defer for default interval
  • rate-limit:5000ms - Rate limit with specific retry-after in milliseconds

How It Works

When a rate-limit or rate-limit:XXXms signal is present, new work is automatically deferred. No explicit coordination needed between operations.

[Request] -> Check signals -> [rate-limit:1000ms] -> Wait 1s -> Process
[Request] -> Check signals -> [no signals] -> Process immediately

Example: API with Rate Limiting

await using var service = new AdaptiveRateService<ApiRequest>(
    async (req, ct) =>
    {
        var response = await httpClient.SendAsync(req.Message, ct);

        if (response.StatusCode == HttpStatusCode.TooManyRequests)
        {
            var retryAfter = response.Headers.RetryAfter?.Delta ?? TimeSpan.FromSeconds(5);
            // Signal will auto-defer subsequent requests
            throw new RateLimitException("Rate limited", retryAfter);
        }

        response.EnsureSuccessStatusCode();
    },
    maxConcurrency: 4);

foreach (var request in requests)
    await service.ProcessAsync(request);
