In queue properties, this setting specifies whether EAServer must redeliver messages that the consumer has not acknowledged. If set to false, messages can be lost if the client fails while the message is being delivered. A value of true guarantees delivery of persistent messages, and guarantees delivery of transient messages as long as the server does not fail or shut down (contingent on the queue settings and message time-to-live property). Setting this property to false for the connection factory yields significantly improved throughput for bulk publishing of transient messages.
