ForTopic

ForTopic<T>

Creates a topic for which there can be multiple queue subscriptions. This enables a 'fan out' scenario.

• A topic and queue pair will be created for message of type T, with a subscription attaching the topic to the queue.
• The topic and queue names will be determined using the supplied (or default if not) ITopicNamingConvention and IQueueNamingConvention, applied to the message type T.
  • These conventions can be overridden on a case-by-case basis using WithName in the topic configuration.
• A dead letter queue will be created, named after the queue name above with an _error suffix.

Example:

x.ForTopic<OrderReadyEvent>();

This describes the following infrastructure:

• An SQS queue of name orderreadyevent
• An SQS queue of name orderreadyevent_error
• An SNS topic of name orderreadyevent
• An SNS topic subscription on topic orderreadyevent and queue orderreadyevent

Further configuration options can be defined by passing a configuration lambda to the ForTopic method.
