Amazon Kinesis Data Streams (KDS)

A managed AWS service for real-time streaming data, with shards that store ordered records for custom consumers to replay.

Definition

Kinesis Data Streams retains data for 24 hours by default (extendable to 365 days), supports provisioned or on-demand capacity, and orders records by partition key within a shard. Enhanced fan-out gives each consumer dedicated throughput.

Exam tip

Need custom, replayable, multi-consumer real-time processing? Use Data Streams. Just delivery to S3 or Redshift? Use Firehose.
