Message ordering and deduplication (FIFO topics)
You can use Amazon SNS FIFO (first in, first out) topics with Amazon SQS FIFO queues to provide strict message ordering and message deduplication. The FIFO capabilities of each of these services work together to act as a fully managed service to integrate distributed applications that require data consistency in near-real time. Subscribing Amazon SQS standard queues to Amazon SNS FIFO topics provides best-effort ordering and at least once delivery.
