Amazon Kinesis Data Streams now supports 10x larger record sizes

Amazon Kinesis Data Streams now supports record sizes up to 10MiB, a tenfold increase from the previous 1MiB limit. This launch enables customers to publish intermittent larger data payloads in their data streams while continuing to use existing Kinesis Data Streams APIs in their applications. This launch is accompanied by a 2x increase in the maximum PutRecords request size from 5MiB to 10MiB.

Amazon Kinesis Data Streams is a serverless data streaming service that enables customers to capture, process, and store real-time data streams at any scale. With this launch, customers no longer need to maintain separate processing pipelines for handling intermittent large records, and can thus simplify their data pipelines. This reduces operational overhead for IoT analytics, change data capture, and generative AI workloads. You can update your stream's maximum record size up to 10 MiB using either the AWS Management Console or the UpdateMaxRecordSize API via the AWS SDK or CLI. Once your stream is configured, you can publish and consume larger records using existing Kinesis Data Streams APIs. You do not incur additional costs to use this capability beyond your regular Kinesis data streams charges.

In conjunction with this launch, AWS Lambda now supports larger payloads up to 6MiB from Kinesis Data Streams.

Amazon Kinesis Data Streams supports large records in the AWS Regions documented here. To learn more about using large records and how common downstream applications handle large records, please see our documentation.
