Fanout to Kinesis Data Firehose delivery streams

You can subscribe Amazon Kinesis Data Firehose delivery streams to Amazon SNS topics, which allows you to send notifications to additional storage and analytics endpoints. Messages published to an Amazon SNS topic are sent to the subscribed Kinesis Data Firehose delivery stream, and delivered to the destination as configured in Kinesis Data Firehose. A subscription owner can subscribe up to five Kinesis Data Firehose delivery streams to an Amazon SNS topic. Each Kinesis Data Firehose delivery stream has a default quota for requests and throughput per second. This limit could result in more messages published (inbound traffic) than delivered (outbound traffic). When there's more inbound than outbound traffic, your subscription can accumulate a large message backlog, causing high message delivery latency. You can request an increase in quota based on the publish rate to avoid adverse impact on your workload.

Through Kinesis Data Firehose delivery streams, you can fan out Amazon SNS notifications to Amazon Simple Storage Service (Amazon S3), Amazon Redshift, Amazon OpenSearch Service (OpenSearch Service), and to third-party service providers such as Datadog, New Relic, MongoDB, and Splunk.

For example, you can use this functionality to permanently store messages sent to a topic in an Amazon S3 bucket for compliance, archival, or other purposes. To do this, create a Kinesis Data Firehose delivery stream with an S3 bucket destination, and subscribe that delivery stream to the Amazon SNS topic. As another example, to perform analysis on messages sent to an Amazon SNS topic, create a delivery stream with an OpenSearch Service index destination. You can then subscribe the Kinesis Data Firehose delivery stream to the Amazon SNS topic.

Amazon SNS also supports message delivery status logging for notifications sent to Kinesis Data Firehose endpoints. For more information, see Amazon SNS message delivery status.
