We just launched Amazon SNS FIFO topics
- otaviofff 6y agoPlease, let me know your comments =)
- ec109685 6y agoCongrats. I still wish it was more ergonomic to build a fan out architecture where clients pull messages out of a queue with AWS. Basically a long-poll style SNS queue.
- otaviofff 6y agoThanks! I’m curious. How is your suggestion different from fanning out messages from the SNS topic, then polling the SQS queues subscribed to the topic?
- ec109685 6y agoSQS doesn’t have the model where the lifetime of the queue is tied to the subscriber, so if you have 1000 subscribers to a single sqs queue, you end up having to go sqs -> sns -> 1000 client created sqs queues. You end having to write code to garbage collect these queues and each message has to be written 1001 times.
- Dunedan 6y agoThe public TPS for SNS FIFO topics are noted as soft limit on https://docs.aws.amazon.com/general/latest/gr/sns.html https://docs.aws.amazon.com/general/latest/gr/sns.html. Is that really a soft limit which can be increased? How do the maximum possible TPS compare with SNS standard topics?

- nicwolff 6y agoPricing vs standard SNS topics, from https://aws.amazon.com/sns/pricing/ https://aws.amazon.com/sns/pricing/ Standard topics: > First 1 million Amazon SNS requests per month are free, $0.50 per 1 million requests thereafter FIFO topics: > Publish API requests are $0.30 per 1 million and $0.017 per GB of payload data > Subscription messages are $0.01 per 1 million and $0.001 per GB of payload data where > Subscription messages are calculated by multiplying the number of published messages and the number of subscriptions. Both filtered and delivered messages count towards the number of subscription messages.
