azure storage queue message live time
Did I understood it right that in Windows Azure Queue storage a message can live for 7 days maximum?
What happens with the message after 7 days?
What happens with the message if you read it once during the 7 days and you don't delete it? I mean you read the message from the queue and set the visibility timeout to let's say 1 minute. What happens after you have read the message (without deleting it) and the 1 minutes timeout visibility expires? I know is back and available on the queue but what happens with the 7 days TTL of that message, is it renewed to 7 days from that point or is 7 days totally since message was created?
Answer
You can now opt-in to infinite TTL for Azure Storage Queue messages by specifying an expiry time of -1 seconds when initially queuing the message.
The time-to-live interval for the message, in seconds. Prior to version 2017-07-29, the maximum time-to-live allowed is 7 days. For version 2017-07-29 or later, the maximum time-to-live can be any positive number, as well as -1 indicating that the message does not expire. If this parameter is omitted, the default time-to-live is 7 days.
