Inbox Durable Templates

Inbox durables are always dynamic durables. By default, FTL automatically generates a durable template for inbox subscribers. The default inbox template has a substantial prefetch and is configured for async acknowledgments.

Administrators may override the default template by defining any standard durable template with prefetch in the appropriate store and setting the inbox_durable field in the endpoint definition. An inbox durable template must be standard with prefetch, and a small durable TTL is automatically applied even if none is configured.

The inbox durable template is used only for inbox subscribers. Other subscribers continue to use the generic dynamic_durable template, if configured.

It is not possible to explicitly name an inbox durable. It is not necessary to unsubscribe from an inbox durable. The inbox durable is automatically destroyed when the subscriber is closed.
