BabelQueue.Sqs

Amazon SQS transport for BabelQueue — "Polyglot Queues, Simplified." Built on the AWS SDK for .NET and the framework-agnostic BabelQueue.Core.

A canonical-envelope publisher and a URN-routed consumer, so an SQS-based .NET service speaks the same wire contract (envelope shape, URN identity, trace propagation) as the PHP/Laravel, Python, Go, Node and Java SDKs. Implements §3 of the broker-bindings contract.

Install

dotnet add package BabelQueue.Sqs

It pulls BabelQueue.Core and AWSSDK.SQS transitively.

Use

using Amazon.SQS;
using BabelQueue.Sqs;

IAmazonSQS sqs = new AmazonSQSClient(); // your AWS config / credentials chain
var url = "https://sqs.eu-central-1.amazonaws.com/123456789012/orders";

// produce
var id = await new SqsPublisher(sqs, url)
    .PublishAsync("urn:babel:orders:created", new Dictionary<string, object?> { ["order_id"] = 1042 });

// consume
var handlers = new Dictionary<string, BabelHandler>
{
    ["urn:babel:orders:created"] = async (env, message, ct) =>
    {
        // env.Data, env.TraceId, env.Attempts ...
    },
};
var consumer = new SqsConsumer(sqs, url, handlers, new SqsConsumerOptions
{
    OnError = (err, env, msg) => Console.Error.WriteLine(err),
});
await consumer.RunAsync(cancellationToken); // long-polls until cancelled

FIFO: new SqsPublisher(sqs, url, fifo: true) (the URL must end in .fifo). For LocalStack/ElasticMQ, point the AmazonSQSClient's ServiceURL there.

Contract mapping (§3)

Envelope SQS
body MessageBody (byte-identical across SDKs)
job (URN) MessageAttributes.bq-job
trace_id MessageAttributes.bq-trace-id
meta.id MessageAttributes.bq-message-id
meta.schema_version MessageAttributes.bq-schema-version (Number)
meta.lang MessageAttributes.bq-source-lang
meta.created_at MessageAttributes.bq-created-at (Number, ms)
attempts reconciled to ApproximateReceiveCount − 1 on receive
reserve / ack visibility timeout → DeleteMessage

Retry is SQS-native: a throwing handler leaves the message undeleted, so SQS redelivers it after the visibility timeout (at-least-once). The poll loop never stops on a bad message — observe via OnError / OnUnknownUrn. The envelope is unchanged (schema_version stays 1); SQS is purely additive.

Build & test

dotnet test

IAmazonSQS is an interface, so the unit tests mock it with Moq — no AWS, no network.
