Amazon Kinesis Data Streams now supports up to 50 enhanced fan-out consumers

Amazon Kinesis Data Streams now supports 50 enhanced fan-out consumers for On-demand Advantage streams. A higher fan-out limit lets customers attach many more independent, low-latency, high-throughput consumers to the same stream—unlocking parallel analytics, ML pipelines, compliance workflows, and multi-team architectures without creating extra streams or causing throughput contention. On-demand Advantage is an account-level setting that unlocks more capabilities and provides a different pricing structure for all on-demand streams in an AWS Region. On-demand Advantage offers data usage with 60% lower pricing compared to On-demand Standard, with data ingest at $0.032/GB, data retrieval at $0.016/GB, and enhanced fan-out data retrieval at $0.016/GB. High fan-out workloads are most cost effective with On-demand Advantage.

Amazon Kinesis Data Streams is a serverless streaming data service that makes it easy to capture, process, and store data streams at any scale. Enhanced fan-out is an Amazon Kinesis Data Streams feature that enables consumers to receive records from a data stream with dedicated throughput of up to 2 MB of data per second per shard, and this throughput automatically scales with the number of shards in a stream. A consumer that uses enhanced fan-out doesn't have to contend with other consumers that are receiving data from the stream. For accounts with On-demand Advantage enabled, you can continue to use the existing Kinesis API RegisterStreamConsumer to register new consumers to use enhanced fan-out up to the new 50 limit.

Support for enhanced fan-out consumers is available in the AWS Regions listed here. For more information on Kinesis Data Streams quotas and limits, please see our documentation. For more information on On-demand Advantage, please see our documentation for On-demand Advantage.
