What about SNS FIFO topic total publish throughput in an account?

Question

https://docs.aws.amazon.com/general/latest/gr/sns.html
In the document, it says:

FIFO topics: 1,000 per account

3,000 messages per second or 20 MB per second, per topic, whichever comes first.

Does it mean the total FIFO topic publish throughput = 3000*1000 =3 million messages/s/account?

Since the standard topic publish throughput is 30,000 messages/s/account, the SNS FIFO topics account level throughput would be much more than the standard one. It is weird.

Accepted Answer

Not exactly, the Publish API throttling for Publish and PublishBatch for FIFO topics of 3,000 messages per second is a regional quota. The 20 MB per second is per a topic quota.

If you had 1,000 topics deployed in US East (N. Virginia) Region then you could only send 3,000 messages per second in that region across all 1,000 topics or 20 MB per topic, whichever comes first.
