The time-to-live value for a publishable document type determines how long instances of that document type remain on the messaging provider. The time-to-live commences when the Broker receives a document from a publishing Integration Server. If the time-to-live expires before the messaging provider delivers the document and receives an acknowledgement of document receipt, the messaging provider discards the document. This happens for volatile as well as guaranteed documents.

For example, suppose that the time-to-live for a publishable document type is 10 minutes. When the messaging provider receives an instance of that publishable document type, the messaging provider starts timing. If 10 minutes elapse and the messaging provider has not delivered the document or received an acknowledgement of document receipt, the provider discards the document.

For a publishable document type, you can set a time-to-live value or indicate that the messaging provider should never discard instances of the document type.
