Amazon Kinesis Data Streams now supports service-managed partition keys for On-Demand Standard and On-Demand Advantage streams, automatically distributing records across shards without requiring customers to specify partition keys to publish data. This capability simplifies data ingestion for workloads where record ordering is not required, eliminating hot partition keys and reducing time to production for streaming workloads. Amazon Kinesis Data Streams is a serverless streaming data service that makes it easy to capture, process, and store data streams at any scale.
