The new service-managed partition key feature automatically balances record distribution across shards in on-demand standard and advantage streams, removing the need for customers to supply partition keys and avoiding issues like hot partitions. This simplification accelerates time to production for streaming workloads where ordering is unnecessary, such as log aggregation and telemetry ingestion.
By relying on the service to allocate records based on available capacity, customers can scale streams to gigabytes per second effortlessly. The capability is accessible by upgrading to the latest AWS SDK or Kinesis Producer Library versions and is available at no additional cost across all AWS commercial regions.
