Amazon Kinesis Data Streams now supports On-Demand write throughput limit of 2 GB/s, a 2x increase from the current limit of 1 GB/s. Amazon Kinesis Data Streams is a serverless streaming data service that makes it easier to capture, process, and store streaming data at any scale. On-Demand is a capacity mode for Kinesis Data Streams that automates capacity management, so that you never have to provision and manage the scaling of resources. It requires you to pay for throughput consumed rather than for provisioned resources, making it easier to balance costs and performance while providing the same availability, durability, and integrations. You can create a new On-Demand data stream or convert an existing data stream into the On-Demand mode with a single-click without requiring any code changes or downtime for your existing applications.
