Today, there are two attributes that can control how events are retried: maximum number of retries and maximum event age.
You can also now configure a custom retry policy that can be set on your event bus targets. With DLQs, you can have greater resiliency and improved recovery from any failure that happens.
They provide a way for failed events or messages to be captured and sent to another system, which can store them for future processing. You can easily enable them on a per target basis and configure them uniquely for each.ĭead letter queues (DLQs) are a common capability in queuing and messaging systems that allow you to handle failures in event or message receiving systems. Both of these give you greater flexibility in how to handle any failures in the processing of events with EventBridge.
Today we’re announcing two new capabilities for Amazon EventBridge – dead letter queues and custom retry policies.
