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

The video tutorial introduces AWS Kinesis Enhanced Fanout, a feature that significantly improves data streaming by allowing each consumer to receive 2 megabytes per second per shard. This feature, available since August 2018, reduces latency and increases scalability, making it ideal for applications requiring low latency and high throughput. Enhanced Fanout is supported by KCL 2.0 and AWS Lambda. The tutorial compares Enhanced Fanout with standard consumers, highlighting cost differences and use cases. Enhanced Fanout is a game-changing feature for big data applications, and its understanding is crucial for upcoming exams.

What is the significance of Kinesis Enhanced Fanout introduced in August 2018?

• It was introduced to replace Kinesis Data Streams.

• It allows for real-time data processing.

• It is a cost-saving feature for AWS users.

• It is considered a game-changing feature.

How does Kinesis Enhanced Fanout improve data throughput?

• By using a new data compression algorithm.

• By reducing the number of consumers per shard.

• By allowing each consumer to receive 2 MB/s per shard.

• By increasing the shard size.

What is a key benefit of Kinesis Enhanced Fanout in terms of latency?

• It maintains a constant latency of 100 milliseconds.

• It reduces latency to an average of 70 milliseconds.

• It increases latency to 200 milliseconds.

• It eliminates latency completely.

When should you use standard consumers over enhanced fanout consumers?

• When you have a low number of consuming applications and can tolerate higher latency.

• When you want to increase costs.

• When you have a high number of consuming applications.

• When you need very low latency.

What is the default limit of consumers that can use enhanced fanout?

• Unlimited consumers

• 20 consumers

• 10 consumers

• 5 consumers
