Polly v8 resilience pipelines for Azure Queue Storage — retry, timeout, and circuit-breaker for QueueClient operations.

Why PollyAzureQueueStorage?

Azure Queue Storage is a durable, scalable message queue — but transient failures (throttling 429, service unavailability 503, gateway timeouts 504) can disrupt your messaging pipeline. PollyAzureQueueStorage wraps QueueClient in a Polly v8 ResiliencePipeline so send, receive, peek, and delete all automatically retry on transient errors.

Completes the Azure storage trio alongside PollyAzureBlob and PollyAzureTableStorage.

Installation

dotnet add package PollyAzureQueueStorage

Quick start

DI registration

`csharp services.AddPollyAzureQueueStorage( connectionString: Environment.GetEnvironmentVariable("AZURE_STORAGE_CONN"), queueName: "my-queue", configure: pipeline => pipeline .AddRetry(new RetryStrategyOptions { MaxRetryAttempts = 3, Delay = TimeSpan.FromSeconds(1), BackoffType = DelayBackoffType.Exponential, ShouldHandle = QueueStorageTransientErrors.IsTransient, }) .AddTimeout(TimeSpan.FromSeconds(30)));

// Use via DI public class QueueService(ResilientQueueClient queue) { public async Task SendAsync(string message, CancellationToken ct = default) => await queue.SendMessageAsync(message, ct); } `

WithPolly() extension on existing QueueClient

`csharp var queueClient = new QueueClient(connectionString, "my-queue");

var resilient = queueClient.WithPolly(pipeline => pipeline.AddRetry(new RetryStrategyOptions { MaxRetryAttempts = 3, Delay = TimeSpan.FromSeconds(1), BackoffType = DelayBackoffType.Exponential, ShouldHandle = QueueStorageTransientErrors.IsTransient, }));

await resilient.SendMessageAsync("hello"); var messages = await resilient.ReceiveMessagesAsync(maxMessages: 10); `

API surface

Method Description
SendMessageAsync(string, CancellationToken) Enqueue a plain-text message
SendMessageAsync(BinaryData, CancellationToken) Enqueue binary/JSON message
ReceiveMessagesAsync(int, TimeSpan?, CancellationToken) Dequeue up to N messages
PeekMessagesAsync(int, CancellationToken) Peek without dequeuing
DeleteMessageAsync(string, string, CancellationToken) Delete after processing
ExecuteAsync(Func<CancellationToken, ValueTask>, CancellationToken) Custom operation

Transient error predicate

QueueStorageTransientErrors.IsTransient handles:

Exception Condition
RequestFailedException Status 429 (throttled), 503 (unavailable), 504 (gateway timeout)
HttpRequestException Network-level failure
TaskCanceledException Timeout or cancellation
