AWS Certified Data Engineer – AssociateData Ingestion and TransformationHard
A gaming company collects telemetry data from millions of players, generating petabytes of data daily. This data needs to be processed in near real-time to detect fraudulent activities and identify emerging game trends. The processing requires complex transformations, aggregations, and pattern matching over sliding windows. The solution must be fully managed, highly scalable, and support custom code. Which AWS service is most suitable for this real-time data transformation?
- AAWS Glue Batch ETL
- BAmazon Kinesis Data Analytics for Apache Flink
- CAmazon Kinesis Data Firehose
- DAmazon Redshift Spectrum
Show answer & explanationAnswer & explanation
Correct answer: B. Amazon Kinesis Data Analytics for Apache Flink
Amazon Kinesis Data Analytics for Apache Flink is a fully managed service that allows you to process and analyze streaming data in real time using Apache Flink. It is ideal for complex, stateful transformations, aggregations, and pattern matching over sliding windows, supports custom Java/Scala/Python code, and is highly scalable for petabyte-scale streaming data.
Why the other options are wrong
- A. AWS Glue Batch ETL is for batch processing of historical data, not for real-time streaming data transformation and analysis.
- C. Kinesis Data Firehose is primarily for loading streaming data to destinations with basic transformations, not for complex, stateful real-time analytics with custom code.
- D. Amazon Redshift Spectrum allows querying data directly in S3 using Redshift, but it's for analytics on data at rest, not for real-time, in-stream transformations and complex pattern matching.
Kinesis Data Analytics for Apache Flink
A fully managed service for processing and analyzing streaming data in real time using Apache Flink, enabling complex, stateful transformations and custom code execution.
- Fully managed Apache Flink
- Real-time, stateful stream processing
- Supports custom Java/Scala/Python code
Memory trick: Flink flows with smart real-time insights.
