Announcing high-throughput mode for Amazon SNS FIFO Topics

Services
Amazon SNS now supports high-throughput mode for SNS FIFO topics, with default throughput matching SNS standard topics across all regions. When you enable high-throughput mode, SNS FIFO topics will maintain order within message group, while reducing the de-duplication scope to the message-group level. With this change, you can leverage up to 30K messages per second (MPS) per account by default in US East (N. Virginia) Region, and 9K MPS per account in US West (Oregon) Region and Europe (Ireland) Region, and request quota increases for additional throughput in any region.
Amazon SNS FIFO topics provides message ordering, message grouping, and de-duplication when delivering to Amazon SQS queues. By default, SNS FIFO topics provide 300 MPS per message group ID, and 3K MPS per topic, and topic level de-duplication. To get higher throughput, you can distribute your messages across message groups, and enable high-throughput mode by setting the **FifoThroughputScope** topic attribute to **MessageGroup.**
We now have increased default limits for SNS FIFO topics across all commercial and the AWS GovCloud (US) Regions.
