Notes:
- 1 KB is measured as 1000 bytes. Messages can include up to ~100 bytes of internal metadata that counts towards total message limits.
- Messages in a queue that have not been consumed after four days are deleted from the queue. Queues does not delete messages in the same queue that have not reached this limit.
