License-number assignment must process requests in order with exactly-once style handling, while citizen notification blasts can be best-effort. Which queue choice is correct?
Select an answer to reveal the explanation.
Short Explanation
FIFO is the numbered deli ticket for license IDs; standard queues are the flyer drop for “we’ll get to you.” Don’t flip those—or hope S3 overwrites and email somehow serialize IDs.
Full Explanation
SQS FIFO queues provide ordering and exactly-once processing semantics within a message group, which fits sequential license-number assignment. Standard queues offer higher throughput with at-least-once, best-effort ordering suitable for notifications. Misusing standard queues or non-queue mechanisms for strict ordering risks duplicates and races.
