latency
Is an uncited latency statistic from 8 years ago still relavent? micro.fragdev.com/daw (talk) 14:30, 11 April 2015 (UTC)

Message delivery
In its current form, the article states that Amazon SQS does not guarantee that the recipient will receive the messages in the order they were sent by the sender and that SQS has at-least-once delivery. While this is technically true, it is also dated. Since then, Amazon introduced FIFO queues as an option (cf. http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/FIFO-queues.html), which deliver in-order and exactly-once, although at a limited rate. --Manny (talk) 11:15, 11 April 2017 (UTC)

Polling
SQS messaging is a polling architecture, and charges users a fixed rate for every 20 seconds they spend asking a queue whether it has messages or not. — Preceding unsigned comment added by 206.252.203.42 (talk) 22:22, 18 September 2018 (UTC)
