AWS Kinesis Data Streams On-Demand Advantage Offers Warm Throughput Scale-Down

feature

AWS Kinesis Data Streams now supports scaling down ingest capacity for On-demand Advantage streams with warm throughput. This new feature optimizes downstream compute costs and performance by efficiently removing excess capacity after traffic spikes. Users can configure this by setting a new warm throughput value equal to or smaller than the existing amount, providing more control over stream provisioning. The capability is available at no additional cost for all on-demand streams with On-demand Advantage mode enabled.

  • Bidirectional capacity management for on-demand streams
  • Monitor stream behavior with CloudWatch metrics
Features (1)
  • Kinesis Data Streams On-Demand Advantage now scales down capacity

    Amazon Kinesis Data Streams now supports scaling down ingest capacity for On-demand Advantage streams with warm throughput. This allows users to proactively reduce write throughput capacity after transient bursts, optimizing costs and maintaining performance by removing excess capacity.

Enhancements (1)
  • Bidirectional capacity management for on-demand streams

    The warm throughput feature now enables bidirectional capacity management: users can scale up by configuring a higher value for forecasted events or scale down by setting a lower value after a burst. The stream adjusts to the requested capacity or the amount needed for peak ingest within the last hour, whichever is higher, to prevent accidental under-provisioning.

Notes (1)
  • Monitor stream behavior with CloudWatch metrics

    Users can monitor the effects of scale-down operations and understand stream capacity using Amazon CloudWatch metrics like IncomingBytes, IncomingRecords, and WriteProvisionedThroughputExceeded. The OpenShardCount field from the DescribeStreamSummary API also helps track shard count changes over time.
