This topic describes how to extend the retention period of a message in Simple Message Queue (formerly MNS).
To extend the retention period of the message, call the SetQueueAttributes operation to set the MessageRetentionPeriod parameter. The MessageRetentionPeriod parameter specifies the retention period of a message. After the retention period expires, the message is deleted from the queue. Unit: second. The default value of the Message RetentionPeriod parameter is 345,600 seconds (4 days). You can set this parameter to a value that ranges from 60 seconds (1 minute) to 604,800 seconds (7 days).
