DEA-C01 Data Ingestion and Transformation Practice Question
A company is designing a data ingestion pipeline for real-time analytics. The source is a relational database, and the target is Amazon Redshift. The pipeline must handle schema changes in the source database automatically. Which combination of services should be used?
⚠ Common exam trap
Many exam-takers choose Kinesis and Lambda (Option D) because they associate 'real-time' with streaming, but they overlook that DMS is the native AWS service for CDC from relational databases, and Glue is required for schema evolution, not just any streaming service.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS DMS and AWS Glue
AWS DMS (Database Migration Service) can capture ongoing changes from a relational database source using Change Data Capture (CDC) and replicate them to Amazon Redshift. AWS Glue can be used to handle schema evolution by crawling the source and updating the target schema, ensuring the pipeline adapts to schema changes automatically. Together, they provide a real-time ingestion pipeline with schema flexibility.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Amazon S3 and Amazon Athena
Why it's wrong here
Athena does not automate schema evolution for Redshift ingestion.
- ✓
AWS DMS and AWS Glue
Why this is correct
DMS captures changes, Glue can detect and apply schema changes.
- ✗
AWS Glue and Amazon Redshift COPY
Why it's wrong here
Glue alone does not capture CDC from a database; COPY is for bulk loads.
- ✗
Amazon Kinesis Data Streams and AWS Lambda
Why it's wrong here
Kinesis requires custom CDC implementation; Lambda would need to handle schema changes manually.
