AWS Certified Data Analytics Specialty 2021 - Hands-On! - Kinesis Consumers

The video tutorial covers various methods to consume data from Kinesis Data Streams, including the use of the Kinesis SDK, Kinesis Client Library (KCL), and Lambda. It explains the polling mechanism, its constraints, and how multiple consumers affect throughput. The tutorial also discusses the deprecated Kinesis Connector Library and its alternatives, such as Kinesis Firehose and Lambda. Additionally, it highlights the use of DynamoDB for coordination and checkpointing in KCL and the role of Lambda in real-time data processing and notifications.

What is the maximum aggregate throughput per shard for classic consumers in Kinesis Data Streams?

• 1 MB for producers, 2 MB for consumers

• 5 MB for consumers only

• 2 MB for producers, 1 MB for consumers

• 3 MB for both producers and consumers

Which library is primarily used for reading records from Kinesis Data Streams and supports multiple programming languages?

• Apache Spark

• Kinesis Connector Library

• Kinesis Client Library (KCL)

• Kinesis SDK

What is the role of DynamoDB in the Kinesis Client Library (KCL) setup?

• To store data streams

• To coordinate and checkpoint data processing

• To replace Kinesis Firehose

• To enhance data throughput

Which library has been largely replaced by Kinesis Firehose and AWS Lambda for writing data to AWS services?

• Apache Spark

• Kinesis Connector Library

• Kinesis SDK

• Kinesis Client Library (KCL)

What is a key feature of AWS Lambda when integrated with Kinesis Data Streams?

• It cannot interact with other AWS services

• It can only process data in batches of 1000 records

• It requires manual scaling for data processing

• It can perform lightweight ETL and trigger real-time notifications

How does AWS Lambda handle data from Kinesis Data Streams?

• By using a fixed batch size of 500 records

• By using a polling mechanism

• By using a push mechanism

• By using a configurable batch size

Which of the following is NOT a destination for data processed by AWS Lambda from Kinesis Data Streams?

• Redshift

• DynamoDB

• Amazon S3

• Google Cloud Storage
