AWS Certified Data Analytics Specialty 2021 - Hands-On! - Kinesis Enhanced Fan Out

The video tutorial discusses AWS Kinesis Enhanced Fan-Out, a feature that allows multiple consumer applications to receive data streams with reduced latency and increased throughput. It explains how Enhanced Fan-Out differs from standard consumers, offering 2 megabytes per second per shard per consumer, and highlights its benefits such as scalability and lower latency. The tutorial also covers the cost implications and the conditions under which Enhanced Fan-Out should be used. The feature is considered game-changing and is expected to be included in AWS certification exams soon.
