Amazon SQS Scheduler

Amazon SQS includes a DelaySeconds property, which can be used to defer message delivery. MassTransit can use this feature to provide scheduled message delivery.

Scheduling messages

To enable the Amazon SQS message scheduler:

var busControl = Bus.Factory.CreateUsingActiveMq(cfg =>
{
    cfg.UseAmazonSqsMessageScheduler();

    cfg.Host("region", hc =>
    {
        hc.Credentials(...);
    });
}

WARNING

Unscheduling messages is not supported using Amazon SQS delayed delivery.

Redelivery

Amazon SQS delayed delivery can be used with the UseScheduledRedelivery feature, which is explained in the exceptions section.
